A-1 iii EXECUTIVE SUMMARY On July 19, 2007, the Federal Energy Regulatory Commission (FERC) issued an Order Accepting Surrender And Dismissing Application For Subsequent License clearing the way for the removal of the Dillsboro Dam and Powerhouse (FERC# 2602) on the Tuckasegee River, Jackson County, NC Pursuant to this order, the North Carolina Division of Water Quality issued a 401 Water Quality Certification with Additional Conditions (November 21, 2007) for dam and powerhouse removal requiring Duke Energy Carolinas, LLC to conduct at least two (2) fish and aquatic macroinvertebrate collections from the Tuckasegee River at different seasons before dam removal Inasmuch as dam demolition was originally scheduled for early 2009, macroinvertebrate and fish sampling was initiated in 2008 at four locations in the river in the vicinity of Dillsboro Project Two sampling locations were upstream of the dam and two were downstream As dam removal was delayed until early 2010, the first year of post dam- removal biological sampling occurred in 2010 The objective of this monitoring was to comply with the 401 Certification by assessing macroinvertebrate and fish populations during May and October for one year prior to and the first three years following removal of the Dillsboro Dam Measured water quality parameters (temperature, dissolved oxygen concentration, specific conductance, and pH) at the time of macroinvertebrate collections appeared to indicate little negative impact to resident benthic communities. Macroinvertebrate collections at four locations on the Tuckasegee River in May and October of 2008 and 2010 — 2012 yielded total taxa counts ranging from 41 to 128 taxa The numbers of Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa ranged from 2 to 51 Macroinvertebrate collections at the reservoir location always demonstrated the lowest numbers of total and EPT taxa of any location sampled, irrespective of season in 2008 and 2010. Resulting water quality bioclassifications based on the macroinvertebrate communities collected at the reservoir location were Poor in 2008 and increased to Good -fair and Fair in 2010 following dam removal The three riverine locations, with their more heterogeneous habitat and flowing water, supported diverse macroinvertebrate communities resulting in better water quality bioclassifications (ranging from Fair to Good). By 2011, the observed benthic community metrics indicated the former reservoir location was becoming more similar to the other three riverine locations. Collections of total taxa and EPT taxa at River Mile (RM) 31.8 increased and were similar to values collected at the other three riverine locations. The 2012 data corroborated the 2011 findings indicating that macroinvertebrate communities and thus water quality bioclassifications were Good throughout the river. iv Temperature, dissolved oxygen concentration, and specific conductance were measured during fish sampling and indicated little impact on the resident fish community Fish collections at four locations on the Tuckasegee River in May and October of 2008 and 2010 — 2012 demonstrated an assemblage composed of 39 species, one hybrid sucker combination, and one hybrid sunfish combination, representing seven families These species are typical of those expected for this drainage and similar to those collected in an earlier study (2001 — 2002) of the same river reach This fish community included two species of special concern to both the North Carolina Wildlife Resources Commission and the United States Fish and Wildlife Service; the _wounded darter and the olive darter. While the wounded darter was collected upstream and downstream of the Dam, the olive darter was first collected upstream of the demolished Dam beginning in May 2011 The most species of fish were always collected at RM 31.6 (except in May 2011 when RM 33.7 tied for the most species), and the least number of species were always found at RM 31 8 ( Dillsboro Reservoir and its successor), immediately upstream of the Dam The fish community at RM 31.8 was largely composed of rock bass and redbreast sunfish before demolition, but this centrarchid domination shifted in less than one year after demolition to a community dominated by cyprmids Meanwhile, the communities at the other three riverine locations (RMs 27 5, 31.6, and 33 7) were always dominated by cyprinids. Pollution tolerance data indicated the fish community at RM 31.8 had the highest percentage of individuals tolerant of pollution and the fewest number of species considered intolerant of pollution Trophic data similarly indicated the fish community at RM 31.8 was atypical compared to those sampled in other nearby reaches of the Tuckasegee River, though these differences decreased after dam demolition. Macroinvertebrate and fish communities in Dillsboro Reservoir were atypical of those occurring in riverine locations upstream and downstream in the Tuckasegee River in 2008. Following dam removal in 2010, both macroinvertebrate and fish communities shifted noticeably within a few months The macroinvertebrate community in the reservoir location was similar to communities in the nverine locations by 2011. The fish community in the reservoir location also changed dramatically with time but was still slightly atypical of those found in the riverine locations by 2012. v LIST OF TABLES Table Title Page 1 -1 River mile designation (upstream from the confluence of the Tuckasegee and Little Tennessee rivers) of Tuckasegee River sampling locations, associated description relative to the Dillsboro Dam, and GPS coordinates ..... 1 -3 2 -1 Description of available habitats at four macromvertebrate sampling locations on the Tuckasegee River near the Dillsboro Project in 2008, 2010, and 2011... .2-10 2 -2 Water quality parameters measured at four Tuckasegee River sampling locations near the Dillsboro Project, May and October, 2008, 2010, and 2011...... 2 -11 2 -3 Total and EPT taxa numbers, Biotic Index values and scores, EPT scores, and Bioclassifications for macromvertebrate locations sampled on the Tuckasegee River near the Dillsboro Project during May and October of 2008, and 2010 — 2012 ........ ............................... ........ 2 -12 . . .. . .. ......... 3 -1 Water quality parameters measured during electrofishing collections on the left (L) and right (R) ascending banks at four locations on the Tuckasegee River during May and October, 2008 and 2010 — 2012 . ............ ... .... ..... 3 -19 3 -2 Fish species collected during Tuckasegee River surveys in the vicinity of the Dillsboro Project, 2001 — 2002 and from 2008 through 2012 ................ .......... 3 -20 3 -3 Fish species, number, and percent composition observed in all Tuckasegee River fish community collections in the vicinity of the Dillsboro Project from 2008 through 2012.... ..................... 3 -21 3 -4 Tolerance rating, trophic guild of adults, number, and percent composition of fish species collected at four sampling locations on the Tuckasegee River near the Dillsboro Project, May 2008 ...................... ...... ............................... 3 -22 3 -5 Tolerance rating, trophic guild of adults, number, and percent composition of fish species collected at four sampling locations on the Tuckasegee River near the Dillsboro Project, October 2008 ............. 3 -23 3 -6 Tolerance rating, trophic guild of adults, number, and percent composition of fish species collected at four sampling locations on the Tuckasegee River near the Dillsboro Project, May 2010 .............. ... ................. ................. 3 -24 3 -7 Tolerance rating, trophic guild of adults, number, and percent composition of fish species collected at four sampling locations on the Tuckasegee River near the Dillsboro Project, October 2010 ... . .................. ............................... 3 -25 3 -8 Tolerance rating, trophic guild of adults, number, and percent composition of fish species collected at four sampling locations on the Tuckasegee River near the Dillsboro Project, May 2011 ................................ ............................... 3 -26 3 -9 Tolerance rating, trophic guild of adults, number, and percent composition of fish species collected at four sampling locations on the Tuckasegee River near the Dillsboro Project, October 2011. ... ............... . ............................... 3 -27 vi LIST OF TABLES (Continued) Table Title Page 3 -10 Tolerance rating, trophic guild of adults, number, and percent composition of A -3 Macroinvertebrates collected at RM 31 8 on the Tuckasegee River near the fish species collected at four sampling locations on the Tuckasegee River near A -26 A -4 Macroinvertebrates collected at RM 33.7 on the Tuckasegee River near the the Dillsboro Project, May 2012... .............. 3 -28 3 -11 Tolerance rating, trophic guild of adults, number, and percent composition of fish species collected at four sampling locations on the Tuckasegee River near the Dillsboro Project, October 2012. ... ..... ..... 3 -29 3 -12 Three most abundant species of fish (percent of total number) collected at four sampling locations on the Tuckasegee River near the Dillsboro Project, 2008 and 2010 — 2012 .................. .. .. ... ............................ .. .... ............. 3 -30 3 -13 Pollution tolerance and trophic status metrics, ratings, and associated scoring criteria as defined by NCDENR for the Little Tennessee River basin ( NCDENR 2006b) .. ..... 3 -31 3 -14 Summary of pollution tolerance rating and the number of Intolerant fish species collected at four sampling locations on the Tuckasegee River near the Dillsboro Project, 2008 and 2010 — 2012.. ....................... .3-32 3 -15 Summary of trophic status of fish collected at four sampling locations on the Tuckasegee River near the Dillsboro Project, 2008 and 2010 — 2012.

The Dillsboro Hydroelectric Project (FERC# 2602) is located on the Tuckasegee River in the Town of Dillsboro, Jackson County, NC (Figure 1 -1). The project originally consisted of a dam, powerhouse, and reservoir. Constructed in 1913, the project has had various owners, and is currently owned by Duke Energy Carolinas, LLC (Duke Energy). The Dillsboro Dam (Dam) impounded the Tuckasegee River at River Mile (RM) 31.7. The Dam was a concrete masonry structure about 310 ft long and 12 ft high (Figure 1 -2). The powerhouse consisted of a reinforced concrete substructure, a wood/steel superstructure, and two generating units The reservoir upstream of the Dam had a surface area of about 15 ac and was approximately 0 8 mi long. The installed generation capacity of the Dillsboro Project was 225 kW. The average annual generation for the project from 1958 to 2002 was 912 MWh, and electricity was last generated there in 2004. DAM REMOVAL Relicensmg activities associated with Duke Energy's Nantahala Area Hydroelectric Projects identified the removal of the Dam as a key component to various stakeholder settlement agreements supporting significant gains in aquatic habitat in the Tuckasegee River (Duke Energy 2003). An agreement to remove the Dam was reached with all involved tribal, state, and federal agencies and resulted in a Federal Energy Regulatory Commission (FERC) Application for Surrender (Duke Energy 2004) which was approved by the FERC on July 19, 2007 (Order Accepting Surrender And Dismissing Application For Subsequent License). The North Carolina Division of Water Quality (NCDWQ) outlined procedures and 1 -1 monitoring requirements associated with dam demolition in an approved Section 401 Water Quality Certification with Additional Conditions issued November 21, 2007 and modified April 13, 2010. Initial removal of sediment deposits from Dillsboro Reservoir was slated for 2008 with dam removal scheduled for early 2009 These dam removal activities were subsequently delayed due to litigation with Jackson County, NC Following resolution of the litigation, sediment removal occurred in the latter months of 2009, the powerhouse was razed in January 2010, dam demolition commenced February 3, 2010, and overall project demolition ended May 11, 2010 (Figure 1 -3). Shoreline restoration was completed by July 15, 2010. To evaluate responses of resident biological communities to dam removal, the NCDWQ requested Duke Energy sample macroinvertebrate and fish communities in the Tuckasegee River for one year prior to (2008) and the three years immediately subsequent to dam removal (2010 — 2012). Biological sampling was requested twice per year (during the months of May and October) and was conducted at two locations upstream and two locations downstream of the Dam. SAMPLING LOCATIONS Macroinvertebrate and fish sampling occurred at four Tuckasegee River sampling locations identified by river miles upstream from the confluence of the Tuckasegee and Little Tennessee rivers They include a location well downstream of the Dam (RM 27.5), the tailrace of the Dam (RM 316), the Dillsboro Reservoir and its subsequent lentic habitat (RM 31.8), and a riverine location upstream of the influence of the Dillsboro Reservoir (RM 33.7, Table 1 -1 and Figure 1 -1). This report provides sampling methods, results, and discussion for macroinvertebrates (Chapter 2) and fish (Chapter 3). During the summer of 2008, Appalachian elktoe Alasmidonta ravenehana were translocated from the Dam tailrace to an area upstream of the Savannah Creek confluence (Alderman 2009). This is the same area as the upstream most sampling location (RM 33.7). To avoid disturbing the newly transplanted mussels, starting with the October 2008 monitoring, macroinvertebrate and fish sampling activities occurred immediately upstream of the mussel relocation area. The river mile designation for this upstream macroinvertebrate and fish sample location was not changed despite this slight upstream shift in sampling location 1 -2 Table 1 -1.

CHAPTER 2 MACROINVERTEBRATES MATERIALS AND METHODS Macromvertebrate monitoring was conducted on the Tuckasegee River in 2008 and 2010 through 2012. Samples were collected at four locations on the Tuckasegee River (Table 1 -1 and Figure 1 -1) Upstream hydroelectric project operations were coordinated to help control river flow and permit sampling under low -flow conditions. Sample collections occurred on May 5 -6 and October 6 -7 in 2008, on May 6 -7 and October 5 -6 in 2010, on May 11 -12 and October 4 -5 in 2011, and on May 22 -23 and October 9 -10 in 2012 (Figures 2 -1 and 2 -2). The Standard Qualitative Method (SQM) as outlined in the North Carolina Department of Environment and Natural Resources ( NCDENR) Standard Operating Procedures (SOP, NCDENR 2006a and 2012) was used in collecting macroinvertebrate samples at RMs 27.5, 31.6, and 33.7 (riverine habitats). This method involved the use of a variety of nets to collect discrete samples from all major habitats at a particular location. The method also requires a visual search of all major habitats, including habitats such as large logs and rocks which cannot be easily sampled with nets Duke Energy was aware of the presence of the Appalachian elktoe Alasmidonta raveneliana in the Tuckasegee River upstream and downstream of the Dam and the possible presence of the littlewing pearlymussel Pegias fabula downstream of the Dam. Both mussels are listed as Federally Endangered by the United States Fish and Wildlife Service (USFWS). Precautions were taken during this study to avoid disturbing mussels while collecting macroinvertebrate samples. The environment at RM 31.8 (Dillsboro Reservoir and its successor) changed as a result of dam removal and sampling was modified accordingly. In 2008 and 2010, the lentic environment was sampled using the Standard Boat Method (SBM) modification of the SQM ( NCDENR 2006a) The SBM requires collecting bottom samples across the width of the reservoir using a Ponar grab sampler. Nine samples were collected from one transect across the Dillsboro Reservoir during each sampling event. Additionally, macroinvertebrates at RM 31.8 were collected by visual searches of all major habitats and by using a sweep net to 2 -1 sample all available shoreline habitats In 2011 and 2012, this location was sampled via the SQM methods used at the other riverine locations and supplemented with a transect consisting of five Ponar grab samples and kicknet samples of snag areas. All collected organisms were sorted from debris in the field, placed in labeled containers, preserved with 95% ethyl alcohol, returned to the laboratory, and identified to the lowest practicable taxon Taxonomic analysis resulted in a water quality bioclassification for each location, which gives equal consideration to the number of Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa present and the biotic index value Following the NCDENR protocol, a score was assigned to the EPT taxa collected Tolerance values were assigned to all benthic taxa according to their relative tolerance to environmental perturbations and a biotic index value was calculated for all taxa collected at a given location. The mean of the EPT taxa score and biotic index score was used to assign one of five water quality bioclassifications from "Poor" to "Excellent" ( NCDENR 2006a and 2012). Bioclassifications were determined using the Mountain Region criteria with spring (winter - spring Plecoptera omitted) and fall seasonal corrections applied in May and October, respectively. Benthic communities at all Tuckasegee River locations were assessed and compared based on both total and EPT taxa abundance and the resulting water quality bioclassifications. In May 2008, water temperatures ( °C) and dissolved oxygen concentrations (mg/L) were collected in situ at each location using a pre - calibrated YSI Model 55 handheld dissolved oxygen meter. Water samples for specific conductance (µS /cm) were also collected at each location, refrigerated, and returned to the laboratory where the samples were measured with a calibrated Hydrolab® Datasonde Since October 2008, dissolved oxygen, water temperature, pH, and specific conductance were measured in situ using a pre - calibrated Hach® HQ40D water quality meter RESULTS AND DISCUSSION Habitat and Water Quality. The three riverine sampling locations (RMs 27.5, 31.6, and 33.7) had similar habitat consisting of bedrock, boulder, cobble, riffles, pools, sand/silt, woody debris, leaf packs, and root masses (Table 2 -1). Additionally, the aquatic vascular plant, Podostemum covered some of the bedrock and cobble surfaces at RMs 27.5 and 31.6 (downstream of the Dam). The upstream habitats at RMs 318 and 33.7 were comprised more of bedrock and pools, with fewer riffle areas, when compared to the two downstream locations. The available habitat at RM 31 8 (reservoir) in 2008 consisted of silt/sand and detritus substrates with shorelines characterized by vegetation, root masses, woody debris, silt/sand, rocks, and boulders. In 2010, RM 31 8 was a deeper more riverme location (depth up to three to four feet) characterized by poor shoreline habitat (mostly silt/sand) with very small amounts of woody debris and root masses. No riffle areas were available for kicknet sampling, therefore, snag and boulder areas were used The river bed consisted mostly of sand, bedrock, and boulders. By 2011 — 2012, shoreline habitat had improved and root mass areas had increased. The average daily flow in the Tuckasegee River was generally managed to permit safe collections of macroinvertebrates Hydroelectric stations upstream of the Dillsboro Project operated until late afternoon one day before sampling and then discontinued operations until late the next day. This allowed the river level to subside and stabilize before each sampling period. Measured morning flows in 2008 and 2010 — 2011 at the United States Geological Survey gage at Barkers Creek (USGS Gage 03510577) ranged from 386 to 981 cfs during May collections and from 130 to 525 cfs during October collections (Figures 2 -1 and 2 -2) Water temperatures during May collections ranged from 13.6 to 20.9 °C while those in October ranged from 11 5 to 19.0 °C (Table 2 -2). The highest water temperatures measured during a specific sampling season have varied among the four locations and may be a reflection of sample collection times. Locations with lower temperatures were sampled early in the morning while those with the highest temperatures were sampled late in the day Dissolved oxygen concentrations during May collections ranged from 8.6 to 10.3 mg/L while those measured in October ranged from 8 4 to 10 9 mg/L (Table 2 -2). Dissolved oxygen levels were well above state standards for the support of aquatic life Conductivity ranged from 20.5 to 29.1 pS /cm during May sampling while measurements collected in October ranged from 22.5 to 44.6 pS /cm (Table 2 -2). Specific conductance was low for all Tuckasegee River samples and generally increased with downstream direction, being highest at RM 27.5 (most downstream location). 2 -3 Measurement of pH was initiated in October 2008 Observed pH values during May collections ranged from 7.0 to 7 5 while those measured in October ranged from 6.8 to 8.5 (Table 2 -2). Measured pH values showed no consistent temporal or spatial patterns and were all within state standards. Removal of the Dillsboro Dam and its reservoir had little observable impact on water quality in the river There was no noticeable difference in any of the measured water quality parameters observed in 2008 (prior to dam removal) compared to any of the post dam removal years (2010 through 2012). Similar observations were made during a more rigorous analysis of water quality variables collected before and after dam removal (Quinn 2012). Total Taxa. Total taxa numbers collected at the four Tuckasegee River sampling locations in May 2008 ranged from 59 to 84 (Table 2 -3; Figure 2 -3; and Appendix Tables A -1 through A -4). Total taxa numbers were highest at RMs 27.5, 31.6, and 33.7 (riverine locations) and exceeded 80 taxa at each location. The lowest total taxa number (59) was collected at RM 318 (reservoir) in May Total taxa numbers collected at all locations in October 2008 exhibited a somewhat similar trend to May and ranged from 41 to 83. The highest totals were observed at RMs 27.5 and 31.6 (83 and 77, respectively), an intermediate value (65) was measured at RM 33.7, and the lowest total (41) was collected at RM 31 8 (reservoir) The total taxa numbers collected from each location in 2008 were generally highest in May, except at RM 27.5 where the October total was greatest. The sampling location at RM 31 8 (reservoir) had the lowest number of total taxa collected during both sampling periods in 2008. The total numbers of taxa collected in both May and October 2010 were higher at each location in comparison to those collected in May or October 2008. Total taxa collected in 2010 ranged from 70 to 96 in May and 78 to 115 in October In 2010, the highest number of taxa collected in May was at RM 33.7 (96) and in October at RM 31.6 (115) As in 2008, the lowest taxa numbers collected in both May and October 2010 were observed at RM 31.8. In 2008, the highest taxa numbers were generally collected in May, but in 2010 the highest taxa numbers were generally collected in October. The total numbers of taxa collected in both May and October 2011 at each location again increased, with the exception of Location RM 316 which decreased slightly in October from 115 taxa in 2010 to 112 taxa in 2011. The numbers of taxa collected from all four locations 2 -4 in 2011 were generally similar in May and October, except at RMs 31 8 and 33.7, which were lower in May and October, respectively The number of taxa collected in 2011 ranged from 102 to 114 in May and from 95 to 117 in October. In 2011, the highest number of taxa was collected from RM 27.5 in both May and October and the lowest number was collected from RM 31.8 in May and RM 33.7 in October. The total numbers of taxa collected in both May and October 2012 again generally increased and were usually the highest collected during this study. The numbers of taxa collected from the four locations in May ranged from 112 to 128 and the number collected at RM 31.8 was the second highest total observed (119). The numbers of taxa collected in October ranged from 105 to 120. The highest number of taxa was collected from RM 31.6 in both May and October and the lowest number was collected from RM 33.7 in May and RM 31.8 in October Macroinvertebrate studies of the Tuckasegee River in the vicinity of the Dillsboro Project by NCDENR have generally demonstrated similar numbers of total taxa as Duke Energy found during 2008 — 2012. The NCDENR Basinwide Assessment Program collected macroinvertebrate samples in the Tuckasegee River at State Road (SR) 1378 (approximately one mile downstream of the Dam, NCDENR 2005 and 2011). This NCDENR location is in the vicinity of the RM 31.6 sample location and a total of 75, 84, and 75 taxa were reported there in 1999, 2004, and 2009, respectively. These totals are comparable to the 81 and 77 taxa Duke Energy collected in May and October 2008, respectively, from RM 31.6, but were lower than Duke Energy collections in 2010 — 2012 In addition, an August 2001 macroinvertebrate study of the Tuckasegee River by Duke Energy, for the Nantahala Area hydro relicensing (Duke Energy 2003), demonstrated lower numbers of total taxa. Three sample locations in 2001 (Locations T1, T3, and T4) were in the same general vicinity as the three riverine locations sampled in 2008 — 2012. Location T1 is in the vicinity of RM 27.5 (most downstream location), Location T3 is in the vicinity of RM 31.6 (tailrace), and Location T4 is upstream of the Dam near RM 33.7 Total taxa collected in 2001 from Locations T1, T3, and T4 were 41, 65, and 72, respectively, and were generally lower than those observed in 2008 and always lower than those observed in 2010 — 2012. Pal EPT Taxa- Numbers of EPT taxa collected in 2008 at the four Tuckasegee River sampling locations ranged from 8 to 35 taxa in May and 2 to 27 taxa in October (Table 2 -3, Figure 2 -4; and Appendix Tables A -1 through A -4). At each location, the numbers of EPT taxa observed in May always exceeded those observed in October. In May and October 2008, the numbers of EPT taxa collected were lowest at RM 31.8 (reservoir) and considerably higher at RMs 27 5, 316, and 33 7 Discounting the RM 31.8 location (reservoir), EPT taxa numbers increased from upstream to downstream in both May and October. The numbers of EPT taxa collected at each sampling location in May and October 2010 were always higher than those collected in May and October 2008. The numbers of EPT taxa collected in 2010 ranged from 26 to 40 taxa during May and 20 to 41 taxa in October. As in 2008, the fewest number of EPT taxa were again collected at RM 31.8 (old reservoir location). In comparison, the numbers of EPT taxa collected at RM 31 8 in May and October 2008 (8 and 2 taxa, respectively) were much lower than the number of EPT taxa collected during May and October 2010 (26 and 20 taxa, respectively) and probably relate to the increasing lotic nature of this location following dam removal. The numbers of EPT taxa collected in May 2011 exceeded those collected in May 2010 at all sampling locations The number of EPT taxa collected in 2011 ranged from 40 to 51 taxa in May and 29 to 43 taxa in October. At each location, the numbers of EPT taxa observed in May always exceeded those observed in October. As in 2008 and 2010, the fewest EPT taxa were again collected at RM 31.8 in 2011, but the number of EPT taxa collected at this location continued to increase, with 40 and 29 EPT taxa being collected in May and October, respectively. Numbers of EPT taxa collected at each sampling location in May and October 2012 ranged from 40 to 47 taxa during May and 35 to 46 taxa in October. For the first time since 2008, the fewest number of EPT taxa was collected in May at a riverme location (RM 27.5) and not the old reservoir location The numbers of EPT taxa collected at RM 31.8 in both May and October have increased steadily since 2008 and probably relate to the increasing lotic nature of this location following dam removal r Prior macroinvertebrate studies of the Tuckasegee River by NCDENR have documented higher numbers of EPT taxa than those observed in 2008 (Figure 2 -5) The NCDENR Basinwide Assessment Program collected 40, 44, and 43 EPT taxa in 1999, 2004, and 2009, respectively, at SR1378 (approximately one mile downstream of the Dam, NCDENR 2005 and 2011) The numbers of EPT taxa collected at either RMs 31.6 or 27 5 (downstream locations) during either of the 2008 sampling periods were lower than those reported by NCDENR. The numbers of EPT taxa collected at RMs 31.6 and 27.5 in May and October 2010 — 2012 have generally been similar to those collected by NCDENR in 1999, 2004, and 2009, except for the higher value of 51 EPT taxa collected at RM 27.5 in May 2011. The numbers of EPT taxa collected at three locations in August 2001 by Duke Energy, for the Nantahala Area hydro relicensing (Duke Energy 2003), was lowest at T1 (downstream) and highest at T4 (upstream location). This observed increasing trend of EPT taxa from downstream to upstream was exactly opposite that noted in May and October 2008. In May and October 2010 — 2012, the number of EPT taxa collected at RMs 27.5, 31.6, and 33 7 were higher than the numbers collected in 2001 and showed no upstream/downstream trends for either sampling period. Water Quality Bioclassification: Water quality bioclassification scores during 2008 varied by location and sample period (Table 2 -3 and Figure 2 -6) Low numbers of EPT taxa and high biotic index scores resulted in a Poor water quality bioclassification score at RM 31.8 (reservoir) in May. Water quality bioclassification scores were generally highest at the riverine locations in May and ranged from Good -Fair to Good. The water quality bioclassification scores at these same three riverine locations in October decreased relative to the May scores and ranged from Fair to Good -Fair The water quality bioclassification score at RM 31.8 in October again rated Poor. In 2010 the water quality bioclassification scores again vaned between locations and sampling periods. While increases in the number of EPT taxa and decreases in the biotic index scores at RM 31 8 in both May and October 2010 led to elevated water quality bioclassification scores compared to 2008, the former reservoir location again had the lowest bioclassification score of the four locations sampled (Fair to Good - Fair). Water quality bioclassification scores at the three riverine locations ranged from Good -Fair to Good. Removal of the Dillsboro Dam appeared beneficial to the Tuckasegee River macromvertebrate community within one year of dam removal. 2 -7 The water quality bioclassification scores in both May and October 2011 continued to vary between locations and sampling periods For the first time in this study, all four sampling locations, including the former reservoir location (RM 31.8), received a water quality bioclassification score of Good in May 2011 October 2011 water quality bioclassification scores ranged from Good -Fair to Good. In 2012 the water quality bioclassification scores in May and October were the highest recorded for each combination of location and month All water quality bioclassifications in May were Good, comparable to results observed in May 2011. Similarly, water quality bioclassifications in October were all Good for the first time The benefits of dam removal to the macroinvertebrate community observed in 2011 (a little over one year since demolition) were repeated in 2012 Water quality bioclassification scores reported by NCDENR at SR1378 were Good and Excellent in 1999 and 2004, respectively, and exceeded most scores noted at RM 31.6 in May and October though the May 2012 bioclassification score was comparable (Figure 2 -7). The 2009 bioclassification score reported by NCDENR ( NCDENR 2011) for SR1387 was Good, which is the same value generally reported for location RM 31.6 from 2010 to 2012. Duke Energy collected macroinvertebrate samples at Locations T1, T3, and T4 in 2001 and all reported water quality bioclassification scores were Good. These 2001 Duke Energy scores are generally comparable to those observed at RMs 27.5, 31.6, and 33.7 from 2010 to 2012. Improvement in water quality bioclassification scores at RM 31.8 were slight in 2010, though by 2011 and 2012, the former reservoir produced bioclassification scores similar to the other riverine locations and comparable to the 2001 scores. Per request of the North Carolina Division of Water Quality (NCDWQ), individual figures showing total taxa, EPT taxa, and water quality bioclassification scores from 2008 — 2012 were made for each of the four sampling locations (Figures 2 -8 to 2 -11). The figures provide a convenient graphical summary of the general improvement of the Tuckasegee River macroinvertebrate community in the vicinity of the removed Dam. 2 -8 SUMMARY AND CONCLUSIONS Measured water quality parameters (temperature, dissolved oxygen concentration, specific conductance, and pH) at the time of macroinvertebrate collections in 2008 and 2010 — 2012 did not suggest any negative impact to resident benthic communities as a result of dam removal in early 2010. Macroinvertebrate collections at four locations in May and October on the Tuckasegee River yielded steadily increasing total taxa counts ranging from 41 to 84 in 2008, from 70 to 115 taxa in 2010, from 95 to 117 taxa in 2011, and culminating in a range from 105 to 128 taxa in 2012 The numbers of EPT taxa similarly increased and ranged from 2 to 35 in 2008, from 20 to 41 taxa in 2010, from 29 to 51 taxa in 2011, and closed with a range from 35 to 47 taxa in 2012. In 2008, the riverine locations (RMs 27.5, 31.6, and 33.7), with their more heterogeneous habitat and flow, supported diverse macroinvertebrate communities and had water quality bioclassifications scores ranging from Fair to Good. Macroinvertebrate collections at RM 318 (the Dillsboro Reservoir) yielded the lowest numbers of total and EPT taxa and resulted in Poor water quality bioclassification scores in 2008. All observed benthic community metrics indicated the benthic community in the Dillsboro Reservoir was atypical of that occurring in nearby upstream and downstream riverine reaches Following dam removal in early 2010, RM 31.8 became more riverine in nature while still maintaining some areas of ponded water. Macroinvertebrate collections in 2010 at RM 31.8 yielded relatively higher numbers of total taxa and EPT taxa and water quality bioclassification scores increased to Fair and Good -Fair. In 2011, the number of total taxa and EPT taxa collected at RM 318 continued to increase. Water quality bioclassifications scores at the former reservoir location increased to Good in May and Good -Fair in October and were similar to scores reported at the other three riverine locations By 2012, total and EPT taxa numbers were generally comparable and all locations received water quality bioclassifications of Good in both May and October. Based on the increasing numbers of total and EPT taxa collected at Location RM 31.8 since dam removal in 2010, the benthic macroinvertebrate community in the former reservoir became similar to the communities observed at the other three riverine locations in 2011 and maintain6d that similarity in 2012. 2 -9 Table 2 -1 Description of available habitats at four macroinvertebrate sampling locations on the Tuckasegee River near the Dillsboro Project in 2008 and 2010 through 2012 2 -10 Rivenne location approximately 55 m in width with a depth of approximately 1 m Available habitat consisted of riffle and pool areas, sand /silt, bedrock, cobble, leaf packs, RM 27.5 woody debris, snags, and root masses Some of the bedrock areas and cobble were covered with aquatic vegetation (Podostemum) Located about 100 m downstream of the Dam, between the tailrace and the Highway 441 bridge The width of the river is approximately 55 m with a depth up to 15 m Available RM 316 habitat consisted of riffle and pool areas, sand /silt, bedrock, cobble, leaf packs, woody debris, snags, and root masses Some of the bedrock and cobble were covered with aquatic vegetation (Podostemum) Reservoir area approximately 100 m upstream of the Dam Habitats included vegetation along the shoreline, root masses, woody debris, silt/sand, rocks, and boulders Substrate consisted of silt/sand and detritus RM 318 Following dam removal, RM 31 8 returned to a more nvenne condition (depth 1 -1 2 m) with poor shoreline habitat Available habitat consisted of riffle and pool areas, silt/sand, bedrock, cobble, leaf packs, woody debris, some snags, and root masses Rivenne location approximately 55 m in width with a depth of approximately 1 5 m RM 33.7 Available habitat included riffle and pool areas, sand /silt, bedrock, cobble, leaf packs, woody debris, snags, and root masses 2 -10 Table 2 -2.

Electrofishing collections at RM 316 (tailrace) and RM 318 (reservoir) were made during periods of higher flow to allow sampling by a small electrofishing boat. Electrofishing collections at RMs 27.5 and 33 7 (the most downstream and upstream locations, respectively) were conducted during periods of relatively low river flow to allow sampling by tote -barge electrofishing equipment During all sampling events, fish were electrofished with pulsed DC current at settings adjusted to achieve maximum sampling efficiency, while minimizing injury to the fish Tote -barge electrofishing was an effective fish sampling method and the numbers of fish collected and the associated time spent sampling each shoreline reach were substantial. To assure fish vitality and reduce shock times, permission was sought and received (approved Water Quality Certification with Additional Conditions - second modification, dated April 13, 2010) to limit tote barge collections to 100 in of shoreline, while maintaining boat electrofishing samples at 200 in of shoreline in 2010 and beyond. Electrofishing collections at RM 316 were subsequently conducted by tote barge during low -flow periods along 100 in of shoreline on each side of the river. All netted fish were identified, measured (total length [TL] in mm), and returned to the river, with the exception of some smaller specimens preserved in formalin and returned to the laboratory for taxonomic identification. Catch data were tabulated as the pooled number of species and individuals collected from both sides of the river at each location Fish communities were further evaluated for their aggregate pollution tolerance rating (i.e., their ability to withstand pollution), and the trophic guilds were evaluated to assess biotic interactions and energy supply. Length frequency histograms for several of the more numerous fish species were compiled for visual analysis. 3 -1 Throughout this study, water temperature ( °C) was measured at each shoreline segment with a calibrated Fluke® thermistor. In 2008 and 2010, dissolved oxygen concentration (mg/L) was measured at each shoreline segment with a calibrated Hach® HQ 10 dissolved oxygen probe while water samples for specific conductance (µS /cm) were collected, refrigerated, and returned to the laboratory where the samples were measured with a calibrated Hydrolab® Datasonde Beginning in 2011, dissolved oxygen concentration and specific conductance measurements were measured in situ with a Hach® HQ40D meter. RESULTS AND DISCUSSION Water Quality: Water temperatures during May collections ranged from 10.4 to 17.4 °C while those in October ranged from 7.8 to 16.3 °C (Table 3 -1). Thermal variability between upstream and downstream locations was likely due to a combination of ambient weather conditions, time of day during sample collection, warming of lentic waters at RM 31.8, and influences of upstream hydroelectric generation regimes. In all instances, water temperatures varied little between the left and right banks at each location. Dissolved oxygen concentrations during May collections ranged from 8.5 to 10 4 mg/L while those measured in October ranged from 8 1 to 116 mg/L. Despite a limited amount of spatial variability in dissolved oxygen concentrations between upstream and downstream locations, all values were more than adequate to support aquatic life and were generally similar between the left and right banks of a location on specific sampling dates. Specific conductance was generally low for all Tuckasegee River samples Conductivity ranged from 19.0 to 32 1 µS /cm during May sampling while those collected in October ranged from 21.9 to 42.0 pS /cm. In general, with the exception of some slight declines observed at RM 31.8 (possibly due to some combination of the lentic habitat and upstream hydroelectric generation to allow boat shocking), specific conductance commonly increased slightly with downstream direction. Specific conductance also varied little between the left and right banks at each location. While very slight water quality differences were noted on a few occasions between the left and right banks of particular locations, anomalous water quality trends have been 3 -2 indiscernible. Additionally, there was no observable difference in water quality parameters during the year prior to dam removal (2008) compared to the years following dam removal (2010 — 2012). Similar observations were made during a more rigorous analysis of water quality variables collected before and after dam removal (Quinn 2012). Temperature, dissolved oxygen concentration, and specific conductance were always within ranges known to support aquatic life and were generally similar between the left and right banks of the four Tuckasegee River sampling locations Based on this finding of homogeneous water quality, left and right bank fish collections were combined for fish community analysis. Fisheries During 2008 electrofishing collections (i e, prior to dam removal), 200 -m shoreline segments were sampled and included all available habitats in each segment Boat electrofishing at RMs 31.6 and 31.8 provided the greatest repeatability, as each location was sampled in similar time intervals (total electrofishing pedal time for the May and October samples at the two locations ranged from 3,617 to 4,044 seconds) Total tote -barge electrofishing time at RMs 27 5 and 33.7 varied in duration from 5,283 seconds to 8,812 seconds per location. Thus, while sampling effort between the left and right banks at each location was generally similar, comparisons of the number of fish collected among most locations (except between RMs 316 and 31.8) may only be representative of relative abundance. As stated earlier, fish collection information at each location is presented as the combined catch from the left and right banks. In 2010 — 2012 (subsequent to dam removal), fish populations along 200 -m lengths of shoreline on each bank of the former Dillsboro Reservoir (RM 31.8) were sampled by a small electrofishing boat Total boat electrofishing time at this location ranged from 2,105 (May 2010) to 4,036 (October 2012) seconds Electrofishing collections at RMs 27.5, 31.6, and 33 7 were via tote -barge along 100 -m lengths of both shorelines and total sample times ranged from 3,392 (October 2012) to 5,804 (October 2010) seconds. After expending 40.0 hours of electrofishing time throughout this study, Duke Energy biologists collected a total of 26,634 fish from the Tuckasegee River near the Dillsboro Dam. These individuals represented 39 species, comprised 7 families, and included 12 cyprinids, 8 percids, 7 catostomids, 7 centrarchids, 3 salmonids, 1 petromyzontid, and 1 cottid (Table 3 -2 and Figures 3 -1 to 3 -7). One new species was added in 2012. Collected species are consistent with those expected based on fish distribution maps of the Tuckasegee River 3 -3 drainage (Menhimck 1991). The least frequently observed species throughout this study (accounting for <0.01% of this total or <3 individuals) included the golden shiner Notemigonus crysoleucas (n =1), western blacknose dace Rhinachthys obtusus (n =1 and the new species first collected in 2012), silver redhorse Moxostoma anasurum (n =2), smallmouth redhorse M breviceps (n =3), green sunfish Lepomas cyanellus (n =1), and walleye Sander vatreus (n =1) A hybrid catostomid combination and a hybrid sunfish combination were also observed but not included in the species total. This total of 39 species compares favorably with the 42 species collected previously in this same reach during five sampling periods from May 2001 to March 2002 (Duke Energy 2003). Infrequently collected fish in the 2001 — 2002 study that were not collected from 2008 to 2012 include common carp Cypranus carpio, longnose dace Rhinachthys cataractae, black bullhead Ameaurus melas, brown bullhead A nebulosus, and yellow perch Perca flavescens. Most of these species were only found in the Dam tailrace location (current study RM 31.6) during the previous study. Two species collected in 2008 — 2012 that were not collected in the 2001 — 2002 study were creek chub Semotalus atromaculatus and silver redhorse. The Tuckasegee River fish community in Jackson County includes several species receiving special attention from the NC Wildlife Resources Commission (NCWRC) and the USFWS (NCDENR 2008, Natural Heritage Program Search performed 11/9/10) based on their limited populations The smoky dace Chnostomus sp 1, wounded darter Etheostoma vulneratum, and olive darter Percana squamata are state and federal species of concern The sicklefin redhorse Moxostoma sp 2 is a state threatened species and is also a candidate for federal listing. The smoky dace was not collected in the vicinity of the Dillsboro Project during 2008 — 2012 sampling or prior efforts in 2001 — 2002 (Duke Energy 2003), however it has been collected well upstream in lower order reaches of the West Fork Bypassed Reach of the Tuckasegee River (Duke Energy, unpublished data). The sicklefin redhorse is the subject of ongoing reintroduction efforts within the Tuckasegee River watershed (Moyer et al. 2009); however, a specimen of confirmed identity was not collected in the vicinity of the Dillsboro Project during this sampling or prior sampling in 2001 — 2002 (Duke Energy 2003). It should be noted that a large redhorse collected in October 2011 at RM 27.5 (Figure 3 -4) possessed traits of a hybrid cross that may have included sicklefin redhorse parentage (Steve Fraley, NCWRC; Dr. Robert Jenkins, Roanoke College; and Dr Wayne Starnes, NC State Museum; personal communications). It has been labeled a Moxostoma hybrid (Table 3 -9). The wounded darter was collected in all years at locations downstream and upstream of the 3 -4 Dam (though never at RM 31 8), similar to findings in 2001 — 2002. The olive darter was only observed downstream of the Dillsboro Dam prior to removal and was finally collected upstream of the Dam at RM 33.7 in May 2011 Though not a specific study objective, hellbender salamanders Cryptobranchus allegamensis were periodically observed, temporarily collected for photographic purposes, and released (Figure 3 -8). These salamanders were observed upstream and downstream of the Dillsboro Dam, both prior to and after demolition Electrofishmg collections in May 2008 resulted in the capture of a total of 35 species and 1 hybrid sunfish combination (Table 3 -4). The highest number of fish species collected (n = 34) at any sampling location was at RM 31.6 (tailrace), while the lowest number of species (n = 13) was found immediately upstream at RM 31.8 (reservoir). The numbers of fish species collected at RMs 27.5 and 33.7 (the most downstream and upstream locations, respectively) were intermediate between the reservoir and tailrace location numbers and ranged from 22 to 24 species A total of 32 species of fish and 1 hybrid sunfish combination were collected in October 2008, the green sunfish was the only new species not previously collected in May (Table 3- 5). October sampling yielded the highest number of species (n = 30) at RM 316 (tailrace) and the lowest number of species (n = 9) at RM 31 8 (reservoir). The numbers of fish species collected at RMs 27.5 and 33 7 were again intermediate between the reservoir and tailrace location numbers and ranged from 18 to 24 species. Electrofishmg occurred in May 2010 after dam removal, but prior to completion of site restoration activities, and resulted in the collection of a total of 29 species (Table 3 -6). The highest number of fish species collected (n = 24) at any May 2010 sampling location was at RM 31.6 (tailrace), while the lowest number of species (n = 14) was found immediately upstream at RM 318 (in the former reservoir). Twenty species of fish were collected at the most upstream (RM 33.7) and downstream (RM 27 5) riverine locations. A total of 29 species of fish were collected in October 2010; the golden shiner and the spotted bass Micropterus punctulatus were the only new species not previously collected since study initiation in 2008 (Table 3 -7) October sampling again yielded the highest number of species (n = 26) at RM 31.6 (tailrace) and the lowest number of species (n = 13) at RM 31.8 (former reservoir) The numbers of fish species collected during October 2010 at 3 -5 RMs 27.5 and 33 7 (the most downstream and upstream locations, respectively) continued to be intermediate between the old reservoir and tailrace location numbers and ranged from 18 to 21 species Electrofishing collections in May 2011 resulted in the capture of a total of 30 species (Table 3 -8) The highest number of fish species collected (n = 24) occurred at two locations, RM 31.6 and, for the first time, a location upstream of the removed Dam at RM 33.7 The lowest number of species (n = 15) was found at RM 31.8 (in the former reservoir). Twenty -two species of fish were collected at the most downstream (RM 27.5) riverine location. A total of 30 species of fish were collected in October 2011 (Table 3 -9); a large catostomid collected at RM 27.5 of undetermined parentage was labeled a hybrid. Electrofishing collections once again yielded the highest number of species (n = 24) at RM 31.6 and the lowest number (n = 15) continued to be found at RM 31.8 (former reservoir). The numbers of fish species collected at RMs 27.5 and 33 7 were again intermediate between the reservoir and tailrace location numbers and were 22 and 20, respectively. Electrofishing in May 2012 resulted in the collection of a total of 33 species (Table 3 -10). The highest number of fish species collected (n = 28) at any May 2012 sampling location was at RM 31.6 (tailrace), while the lowest number of species (n = 21) was found immediately upstream at RM 31.8. This was the first instance where the number of species collected from the former reservoir exceeded 20. The numbers of fish species collected at RMs 27.5 and 33.7 (the most downstream and upstream locations, respectively) continued to be intermediate between the old reservoir and tailrace location numbers and ranged from 24 to 25 species A total of 31 species of fish were collected in October 2012; the western blacknose dace was collected for the first time (at RM 33 7) since study initiation in 2008 (Table 3 -11). October sampling again yielded the highest number of species (n = 23) at RM 31.6 (tailrace) and the lowest number of species (n = 19) at RM 31 8 (former reservoir) Twenty -two species of fish were collected at the most upstream (RM 33.7) and downstream (RM 27.5) riverine locations. The most abundant species of fish collected varied among the four Tuckaseegee River sampling locations (Table 3 -12). During 2008 and 2010 through 2012, the lotic habitat at RMs 27.5, 31.6, and 33.7 were typically dominated by a member of the cyprinid family 3 -6 (Figures 3 -9 to 3 -12). In most cases, the three most abundant species at these riverine locations were cyprinids, except when northern hog sucker Hypentelzum nigricans, mottled sculpin Cottus bairdu, rock bass Amblophtes rupestris, or gilt darter Percina evades were occasionally collected in large numbers While the foremost cyprinid species has primarily been the river chub Nocomis micropogon, and secondarily the Tennessee shiner Notropis leuciodus, it appeared both cyprinid species only came to dominance at RM 31.6 (tailrace) after removal of the Dam. Similarly, while the gilt darter is a major percid contributor to fish collections at RM 27.5, this species was only collected in high abundance at RM 31.6 (tailrace) after removal of the Dam. It appears that dam removal has also altered the fish community immediately downstream from its former location The most abundant species of fish at the Dillsboro Reservoir location (RM 31.8) has undergone some unique shifts following dam removal. Prior to dam removal in May and October 2008, rock bass accounted for over 45% of the fish community at this location, with redbreast sunfish Lepomis auritus being secondary in abundance (approximately 17 to 19 %). These two centrarchid species were able to adapt to and exploit this lentic environment Following removal of much of the lentic environment with dam demolition in early 2010, the centrarchid community underwent a fairly dramatic shift In May 2010, rock bass at RM 31.8 was displaced as the dominant species by redbreast sunfish and, by October 2010, each of these two centrarchid species accounted for less than 10% of the observed fish community. In October 2010, the three most abundant fish species at the former reservoir location were all cyprinids In 2011 there was a brief resurgence of rock bass, accounting for approximately 22 and 14% of the catch in May and October, respectively. Rock bass appear to have come into equilibrium with the new pool habitat at RM 31.8 and typically represented about 15% of that fish community in 2012 The presence of cyprinids at RM 31.8 following dam removal has increased sporadically though the typical riverime cyprinid assemblage of river chubs, Tennessee shiners, and warpaint shiners Luxilus coccogenis tended to give way to whitetail Cyprinella galactura and mirror shiners Notropis spectrunculus. Both species may be more comfortable in waters with moderate flows and more pool habitat (Etnier and Starnes 1993 and Olson 2012) The first mottled sculpins and darter species were collected in the former reservoir just over two years after dam removal. In May 2012, one mottled sculpin and two tangerine darters Perczna aurantiaca were collected followed by one mottled sculpin and two gilt darters in October 2012. Use of this former reservoir habitat by these benthic specialists is another positive indicator that this flowing pool habitat is slowly being utilized by a larger segment of the Tuckasegee River fish community. 3 -7 Pollution Tolerance Rating- The presence or absence of various fish species may provide clues regarding habitat quality, water quality, biotic interactions, and energy supply in a specific water body The ability of fish species to withstand pollution or environmental perturbations has been documented ( NCDENR 2006b). Each collected species is assigned a pollution tolerance rating of Tolerant, Intermediate, or Intolerant (Tables 3 -4 through 3 -I1) While Tolerant species are typically encountered in most fish surveys, a water course is considered stressed when members of these species numerically dominate the sample (Table 3 -13). Conversely, the more Intolerant species encountered in a sample, the less likely the stream is negatively impacted by pollution. NOTE: the following discussion is provided for `information only' as this fish community assessment method was developed for wadeable streams and extrapolation of the specific metric scores to river environments is, as of yet, unverified Pollution tolerance data were analyzed by year to evaluate pre- and post -dam removal fish communities (Table 3 -14). The percentages of Tolerant individuals collected at the three riverine locations (RMs 27.5, 316, and 33.7) in 2008, before dam removal, ranged from 0 00 to 1.76% while the range since 2010 has decreased and measures from 0.00 to 0.46 %. While all of these values have been < 2 %, typifying observations from NCDENR regional reference streams, the percentage of Tolerant individuals at the riverine locations has decreased slightly since dam removal (Western and Northern Mountains criteria, NCDENR 2006b). The percentage of Tolerant individuals in the lentic environment at RM 318 was 22 69% in 2008 and would characterize this location as deviating greatly from an NCDENR regional reference stream. Measured percentages of Tolerant individuals since dam removal in 2010 have steadily declined from 23 76 to 4.25% in 2012, typifying conditions observed in streams that deviate from regional reference streams The former Dillsboro Reservoir has undergone profound declines in the percentage of pollution tolerant individuals since dam removal. Since sampling began in 2008, eleven Intolerant species (silver shiner Notropis photogenis, telescope shiner N telescopus, rainbow trout Oncorhynchus mylass, brook trout Salveltnus fontinalis, rock bass, smallmouth bass Micropterus dolomieu, greenfin darter Etheostoma chlorobranchium, wounded darter, tangerine darter, gilt darter, and olive darter) were collected in this reach of the Tuckasegee River near Dillsboro In 2008, all 11 Intolerant species were collected downstream of the Dam (RMs 27.5 and 31.6), while four were collected at RM 31.8 (reservoir) and six species were collected at the most upstream riverine 3 -8 location (RM 33 7) From 2010 to 2012, nine to eleven Intolerant species have been found at the two nverine sites downstream of the demolished dam while numbers at RM 33 7 have ranged from six to ten The numbers of Intolerant species at the former reservoir location have always been lower than those measured at the riverine locations, however, this difference has decreased each year. The number of Intolerant species collected in the former reservoir has risen from five to eight In summary, the lowest number of Intolerant species collected each year occurred in the lentic habitat of the Dillsboro Reservoir and its successor. While numbers of Intolerant species in the riverine locations have generally been highest, there is optimism regarding the steadily increasing number of Intolerant species found each year at RM 31.8. Despite the gradually decreasing differences in the number of Intolerant species measured since 2008, all locations exceeded the minimum of three Intolerant fish species typically found in NCDENR regional reference streams. Pollution tolerance data collected in 2008, as defined by the percentage of Tolerant individuals and the number of Intolerant species, indicated obvious differences in the fish community at RM 31.8, but dam removal has cause the magnitude of these differences to lessened dramatically with time. Trophic Status Just as tolerance ratings provide clues to fish distributions and pollution impacts, trophic ratings reflect the effects of biotic interactions and energy supply (Tables 3 -4 through 3 -11; NCDENR 2006b). For example, a stream receiving excessive nutrient enrichment may be expected to show an increased abundance of omnivores and herbivores The NCDENR (2006b) rates wadeable western North Carolina mountain streams by two trophic metrics (Table 3 -13), streams classified as regional reference streams have combined percentage of omnivores and herbivores between 10% and 36% or have insectivores comprising between 55% and 85% of the sample Observed percentages outside those ranges indicate that a stream `deviates' or `deviates greatly' from NCDENR regional reference streams for those metrics. Trophic guild data were analyzed by year to evaluate pre- and post -dam removal fish communities (Table 3 -15) The combined percentage of omnivores and herbivores collected in 2008 ranged from 9.5 to 32.3% and the fish communities were generally considered typical for NCDENR regional reference steams except at RM 31.8, where the observed total of 9.5% deviated greatly from regional reference streams. Since dam demolition, the 3 -9 combined percentage of omnivores and herbivores at the three riverme locations has ranged from 18.6 to 30.3% and all values were generally considered typical for NCDENR regional reference steams. Following dam demolition, the combined percentage of omnivores and herbivores collected at the former Dillsboro Reservoir has ranged from 6.4 to 29.3% and only the one value measured in 2012 (6 4 %) would be considered to deviate greatly from a regional reference stream Variable percentages of central stonerollers Campostoma anomalum (herbivore) and river chubs (omnivore) have been collected and account for the occasional low combined percentage of omnivores and herbivores. The percentages of insectivorous fish collected in 2008 before dam removal ranged from 40.1 to 74.4% and generally were considered representative of NCDENR regional reference streams, except in the lentic waters of RM 31.8. There, the insectivore percentage (40.1%) was considered representative of a stream deviating from a regional reference stream Following dam removal in early 2010, the percentages of insectivorous fish measured at all four locations in all three years have ranged from 50.2 to 74.8% All observed insectivorous percentages were considered indicative of values found in NCDENR regional reference streams except one value at RM 31.8 (50.2% in 2011). This value was considered atypical of NCDENR regional reference streams. Piscivorous fish (trout, rock bass, black bass, and walleye) have been collected at each of the four Tuckasegee River sampling locations during every year of this study. While no evaluation criteria have been developed for the percentage of piscivores, values at RMs 27.5, 31.6, and 33 7 (riverine locations) have ranged from 1.7 to 13.8% and were generally less than 10 %. In contrast, the percentage of piscivores at RM 31.8 (reservoir) exceeded 50% before dam demolition and has declined to range from 18.3 to 26.6% following dam demolition In summary, three different trophic metrics indicated dissimilarities between the fish community in the lentic habitat at RM 31.8 (the Dillsboro Reservoir) and those observed at the three riverine locations before the dam was removed in 2008 Following dam removal, the measured trophic parameters at RM 31.8 have gradually trended towards those characteristic of regional reference streams and observed at the three riverine locations (RMs 27.5, 31.6, and 33.7), though natural differences in habitat still persist 3 -10 Length Frequencies. Several Tuckasegee River fish species were collected in sufficient numbers in 2008 and 2010 — 2012 to produce fairly detailed length frequency histograms. Data collection during May and October also permitted a visual assessment of growth within a year. The mountain brook lamprey khthyomyzon greeleyi, eight cypnmds (central stoneroller, whitetail shiner, warpaint shiner, river chub, Tennessee shiner, mirror shiner, telescope shiner, and fatlips minnow Phenacobius crassilabrum), one catostomid (northern hog sucker), one cottid (mottled sculpin), one centrarchid (rock bass), and four percids (greenfin darter, Tuckasegee darter E guttselh, wounded darter, and gilt darter) provided fairly detailed graphs. Mountain brook lampreys collected in the Tuckasegee River near the Dillsboro Project ranged in length from 71 to 173 mm, TL (Figure 3 -13) Spawning occurs from mid -May to early -June and was observed at a temperature of 13 5 °C in Tennessee (Etnier and Starnes 1993). Inadequate collections of very small Tuckasegee River lampreys and indistinct peaks in the length frequency graph make further observations difficult at this time. The maximum TL for mountain brook lamprey collected in the Tuckasegee River near Dillsboro (173 mm) is less than the maximum length noted in Tennessee (181 mm) and in excess of the 162 mm maximum TL from Kentucky (Jenkins and Burkhead 1994) Central stonerollers collected in the Tuckasegee River near the Dillsboro Project ranged in length from 37 to 223 mm, TL (Figure 3 -14) Spawning occurs from early -April to mid -June in Tennessee at peak temperatures of 12 to 14 °C (Etnier and Starnes 1993), and would coincide with the time of Duke Energy's May sampling activities Thus, the first length frequency peak observed in October (modal length range 56 to 60 mm) would represent the sizes of Age 0 fish heading into their first winter. This peak coincides with the first May modal length range peak observed for fish surviving the first winter (i.e, minimal growth during winter). This length range roughly concurs with the observation of Etmer and Starnes (1993) who note central stoneroller standard lengths of 35 to 65 mm after one year. Overlapping or indistinct peaks in the length frequency graph make further conclusions difficult, especially as males grow faster than females and some studies report wide TL ranges for older fish of a given age (Jenkins and Burkhead 1994). The maximum central stoneroller size collected in the Tuckasegee River (223 mm) during this study exceeds the maximum TL (200 mm) reported by (Jenkins and Burkhead 1994) for Virginia but is dwarfed by a 287 -mm TL specimen collected in the Tennessee portion of the Great Smoky Mountains National Park (Lennon and Parker 1960). 3 -11 Whitetail shiners collected in the Tuckasegee River for this study ranged in length from 17 to 156 mm, TL (Figure 3 -15). This species has been observed to spawn on the undersurfaces of rocks and submerged debris during June in NC (Outten 1958), thus no small individuals would be expected in the May samples A large and normally distributed length frequency peak in October (modal length range 31 to 35 mm) represents young -of- the -year fish preparing to endure their first winter. A subsequent May peak (modal length range 36 to 40 mm) represents the size of Age 1 fish who survived the first winter. At this time, the numbers of older fish were too few and the size range too wide to provide more definitive information Outten (1958) observed that males grow larger than females and the oldest individual were four years of age The maximum length observed in the Tuckasegee River near Dillsboro (156 mm) exceeds the maximum lengths of whitetail shiners noted from Tennessee (150 mm) and Virginia (148 mm) by Etnier and Starnes (1993) and Jenkins and Burkhead (1994), respectively. Warpaint shiners collected in the Tuckasegee River for this study ranged in length from 25 to 154 mm, TL (Figure 3 -16) This species has been observed to spawn in June in NC (Outten 1957), so no small individuals would be expected in the May samples. A large and normally distributed length frequency peak in October (modal length range 46 to 50 mm) represents young -of- the -year fish preparing to endure their first winter. A subsequent May peak (modal length range 56 to 60 mm) represents the size of Age 1 fish who survived the first winter. Based on the next apparent October peak (modal length range 86 to 90 mm), this would be the size of Age 1 fish entering their second winter. A subsequent diffuse May peak (modal length range 91 to 100 mm) would represent the lengths of Age 2 fish entering their third summer. Outten (1957) indicated that the majority of warpaint shiners are mature during their third summer and few live beyond Age 2. The maximum length observed in the Tuckasegee River near Dillsboro (154 mm) exceeds the maximum lengths of warpaint shiners noted from Tennessee (120 mm) and Virginia (143 mm) by Etnier and Starnes (1993) and Jenkins and Burkhead (1994), respectively. River chubs collected in the Tuckasegee River ranged in total length from 17 to 240 mm (Figure 3 -17). Spawning is described as occurring in late spring in Tennessee ( Etnier and Starnes 1993) and from late May through June in the Tennessee River system of Virginia (Jenkins and Burkhead 1994). So, while young river chubs might not be expected in May fish collections, some very small individuals were observed. The October length frequency peak (modal length range 56 to 60 mm) represents young -of -the -year chubs entering their first winter while the identical first May peak represents the length of Age 1 fish who 3 -12 survived the winter but exhibited negligible growth. A subsequent October peak for Age 1 fish (modal length range 86 to 90 mm) can be discerned but maturity and sexually dimorphic growth (males grow faster than females) may obscure any further length frequency peaks at this time The largest river chub collected in the Tuckasegee River (240 mm) exceeds the maximum size (227 mm) reported from Virginia (Jenkins and Burkhead 1994) Tennessee shiners collected in the Tuckasegee River near the Dillsboro Project ranged in length from 26 to 87 mm, TL (Figure 3 -18) Outten (1962) describes spawning in late -May to early -June in NC at water temperatures ranging from 18 3 to 25 0 °C. As Duke Energy's May fish collections occurred earlier in the month and at cooler water temperatures (see Table 3 -1), it is unlikely young -of -the -year Tennessee shiners would be collected in May A normally distributed length frequency peak occurred for young -of -the -year shiners in October (modal length range 39 to 40 mm) prior to their first winter A diffuse range of lengths with a peak from 41 to 42 mm was discernible the subsequent May and represented fish surviving their first winter These fish then grew and formed a second October length frequency peak (modal length range 67 to 68 mm) as Age 1 fish. These fish then entered their second winter and emerged as Age 2 fish with another wide range of lengths, peaking from 69 to 70 mm the following May No further length frequency peaks were observed. The life history of this species is poorly known and length frequency data would appear to indicate few fish live beyond Age 2 The tendency for female Tennessee shiners to grow larger than males (Jenkins and Burkhead 1994) may be one factor leading to the diffuse peaks The maximum size collected in the Tuckasegee River (87 mm) exceeds the maximum size (82 mm) reported by Etnier and Starnes (1993) for Tennessee. Mirror shiners collected in the Tuckasegee River ranged in total length from 21 to 80 mm (Figure 3 -19). Olson (2012) studied the biology of this species in western NC, including two Tuckasegee River locations, and determined that spawning likely occurs from April through July with the peak gonadosomatic -index occurring in May. The occurrence of a few very small mirror shiners in May (only following the unseasonably mild winter of 2011 — 2012) corroborated the indication that some spawning may occur prior to May. Young -of -the -year shiners in October have a modal length range of 37 to 38 mm prior to their first winter. Fish surviving this first winter have a diffuse length frequency peak (approximate modal length range 41 to 42 mm) in May and these Age 1 fish increase in size throughout their second summer By October, the modal length range of Age 1 fish is 67 to 68 mm. Age 2 fish collected in May have the same modal length (range 67 to 68 mm) and it appears few fish survive beyond Age 2. Olson (2012) determined that mirror shiners only spawn at Age 2 and 3 -13 that very few fish live to Age 3. The maximum total length of 79 mm reported by Etnier and Starnes (1993) is almost identical to that observed in the Tuckasegee River. Telescope shiners collected in the Tuckasegee River ranged in total length from 20 to 95 mm (Figure 3 -20). Spawning apparently occurs in May and June in Virginia (Jenkins and Burkhead 1994), from mid -April to mid -June in Tennessee (Etnier and Starnes 1993), and has been reported from April to July, with a peak in June, in northern Alabama (Holmes et al. 2010) Little is known about the growth of this species though females apparently grow larger than males and spawning may occur at multiple times during the spawning period (Jenkins and Burkhead 1994 and Holmes et al 2010) Given these conditions, the interpretation of the length frequency graph should be done with caution. The apparent modal length frequency peaks for young -of -the -year, Age 1, and Age 2 shiners in October were from 45 to 48 mm, 57 to 60 mm, and 77 to 80 mm, respectively. The maximum total length of 115 mm reported by Etnier and Starnes (1993) exceeds that observed in the Tuckasegee River. Fatlips minnows collected in the Tuckasegee River ranged in total length from 42 to 113 mm (Figure 3 -21). Spawning is estimated to occur from April to June (Jenkins and Burkhead 1994) and the occurrence of a few very small fish in May collections would appear to substantiate limited spawning prior to May. Young -of -the -year fatlips minnows in October have a modal length range of 57 to 60 mm prior to their first winter. Fish surviving their first winter were poorly collected and exhibited a wide range of lengths By October, the modal length range of Age 1 fish was 85 to 88 mm prior to their second winter. Age 2 fish collected in May again showed a diffuse range of lengths and little additional information can be discerned from the length frequency plot The maximum length of fatlips minnows observed in the Tuckasegee River near Dillsboro (113 mm) was nearly identical to the maximum length noted from Virginia (112 mm), where few fish survive a third winter (Jenkins and Burkhead 1994) Northern hog suckers collected in the Tuckasegee River near the Dillsboro Project ranged in length from 37 to 381 mm, TL (Figure 3 -22). Spawning behavior in Virginia has been reported during April and May (Jenkins and Burkhead 1994) and no small northern hog suckers were found in May collections. An October length frequency peak (modal length range 61 to 70 mm) was noted for young -of- the -year fish Age 1 fish during spring had an identical length frequency peak (modal length range 61 to 70 mm) that indicated negligible growth during winter. Little else could be determined from the length frequency graph. The 3 -14 largest northern hog sucker observed by Jenkins and Burkhead (1994) measured 450 mm TL and easily exceeded the largest fish collected in the Tuckasegee River (381 mm) Mottled sculpins collected in the Tuckasegee River near the Dillsboro Project ranged in length from 18 to 111 mm, TL (Figure 3 -23). Mottled sculpin spawn in cavities beneath stones or other materials from mid -March to mid -Apnl in Virginia (Jenkins and Burkhead 1994). The smallest Tuckasegee River mottled sculpin was an 18 -mm individual collected in May 2012 (following the unseasonably mild winter of 2011 — 2012), thus corroborating this early spawning date in the Tuckasegee River This same small sculpin also had the distinction of being the first collected at RM 31.8 in our study. Even previous collections in 2001 — 2002 failed to collect sculpins in the Dillsboro Reservoir (Duke Energy 2003). Young -of -the -year sculpins collected in October had a modal length frequency peak that ranged from 36 to 40 mm. Age 1 fish collected the following May had a modal length frequency peak ranging from 51 to 55 mm that subsequently increased to range from 66 to 70 mm in October Following winter, Age 2 fish in May had an identical modal length frequency peak (from 66 to 70 mm) based on the length frequency distribution Little additional information could be determined though it should be noted Etnier and Starnes (1993) did not indicate growth of Tennessee mottled sculpins to be as fast The maximum length observed in the Tuckasegee River near Dillsboro (111 mm) was slightly less than the maximum lengths of mottled sculpins noted from Tennessee (114 mm) and Virginia (113 mm) by Etnier and Starnes (1993) and Jenkins and Burkhead (1994), respectively. Rock bass collected in the Tuckasegee River near the Dillsboro Project ranged in length from 27 to 252 mm, TL (Figure 3 -24) Spawning behavior in Virginia occurred from April to July (Jenkins and Burkhead 1994) October modal length frequency peaks from Age 0 through Age 2 fish in the Tuckasegee River ranged from 46 to 50 mm, 76 to 80 mm, and 106 to 110 mm, respectively, and corresponded closely with similar values (45, 80, and 115 mm) measured for Tennessee fish ( Etmer and Starnes 1993). Little additional information could be determined from the length frequency graph based on these collections The largest rock bass observed by Jenkins and Burkhead (1994) in Virginia measured 330 mm TL, though the authors noted fish over 250 mm were rare, and easily exceeded the largest fish collected in the Tuckasegee River (252 mm) Greenfin darters in the Tuckasegee River near the Dillsboro Project ranged in length from 26 to 87 mm, TL (Figure 3 -25). Spawning in Tennessee was presumed to be midsummer ( Etnier and Starnes 1993) and would corroborate the lack of small greenfin darters in May 3 -15 collections Indistinct length frequency peaks precluded any definitive summarization of lengths at specific ages Greenfin darters are thought to have a life span of 4 to 5 years ( Etnier and Starnes 1993). The largest greenfin darter noted by Etmer and Starnes (1993) measured 110 mm and easily exceeded the largest fish collected in the Tuckasegee River Tuckasegee darters, a member of the greenside darter group (Miller 1968), in the Tuckasegee River near the Dillsboro Project ranged in length from 35 to 134 mm, TL (Figure 3 -26). Spawning behavior of greenside darters in Tennessee has been described as early spring ( Etnier and Starnes 1993) and late - February to late -March in Arkansas (Hubbs 1985), corroborating the occasional collection of small Tuckasegee darters in May. An October length frequency peak (modal length range 51 to 55 mm) was noted for young -of -the -year fish prior to their first winter. A presumed Age 1 peak in May (modal length range 56 to 60 mm) was observed and followed by growth to a modal length range of 76 to 80 mm by October. Some Age 2 peaks were discernible but should probably await larger sample sizes for more definitive analysis. Additionally, determination of size classes may be muted by the propensity of males to grow faster and reach larger TLs than females (Jenkins and Burkhead 1994) The largest greenside darter (Etheostoma newmanh) observed by Etnier and Starnes (1993) in Tennessee measured 166 mm and easily exceeded the largest Tuckasegee darter (134 mm) collected near Dillsboro Wounded darters in the Tuckasegee River near the Dillsboro Protect ranged in length from 30 to 80 mm, TL (Figure 3 -27). Spawning behavior in Tennessee has been observed from late -May to late -July ( Etnier and Starnes 1993) and would corroborate the lack of small wounded darters in May collections. Indistinct length frequency peaks precluded any definitive summarization of lengths at specific ages Wounded darters are thought to have a life span of 4 to 5 years ( Etnier and Starnes 1993) The largest wounded darter noted by Etnier and Starnes (1993) measured 81 mm, nearly identical to the length of the largest fish collected in the Tuckasegee River. Gilt darters collected in the Tuckasegee River near the Dillsboro Project ranged in length from 18 to 82 mm, TL (Figure 3 -28). Spawning behavior in Tennessee has been observed in June and early -July ( Etnier and Starnes 1993) and would corroborate the lack of small gilt darters in May collections. An October length frequency peak (modal length range 45 to 46 mm) was noted for young -of- the -year fish, despite sexually dimorphic growth (males grow larger than females) after just three months of age (Jenkins and Burkhead 1994). Low collections of small gilt darters in May complicated the analysis of Age 1 fish during spring. 3 -16 A presumed Age 1 peak in October (modal length range 57 to 58 mm) was identical to the Age 2 peak in May of the subsequent year Little additional information could be determined from the length frequency graph The largest gilt darter observed by Etnier and Starnes (1993) in Tennessee measured 77 mm and was exceeded by the largest fish collected in the Tuckasegee River (82 mm) SUMMARY AND CONCLUSIONS Measured water quality parameters in 2008 and 2010 — 2012 (temperature, dissolved oxygen concentration, and specific conductance) were fairly similar among sampling dates and sites and indicated little impact on the resident fish community. Fish collections at four locations on the Tuckasegee River in May and October of 2008 and 2010 — 2012 demonstrated a diverse assemblage composed of 39 species, one hybrid sucker combination, and one hybrid sunfish combination, representing seven families These species are typical of those expected for this drainage and similar to those collected in an earlier study of the same reach of river in 2001 — 2002. The 2008 — 2012 fish community included two species of special concern to both NCWRC and the USFWS; the wounded darter and the olive darter While the wounded darter was collected upstream and downstream of the Dillsboro Dam site in all years, the olive darter was finally collected upstream of the dam in May 2011. The highest number of fish species was always collected at RM 31.6 (in May 2011, RM 33.7 tied for the highest number of species), and the least number of species was always found at RM 31.8 (reservoir and its successor), immediately upstream of the Dam The fish community at RM 31.8 was dominated by rock bass and redbreast sunfish before demolition, but this centrarchid domination shifted fairly rapidly (in less than one year) to a community dominated by cyprinids. In 2011 and 2012, the RM 31.8 fish community was variably dominated by cyprinids, catostomids, and centrarchids. Meanwhile, the communities at the other three riverine locations (RMs 27.5, 316, and 33.7) were always dominated by cyprinids or the gilt darter. Pollution tolerance data indicated the fish community at RM 31.8 had the highest percentage of individuals tolerant of pollution and the fewest number of species considered intolerant of pollution though these differences became less noticeable by 2012. Trophic data similarly indicated the fish community at RM 31.8 was atypical compared to those sampled in other nearby reaches of the Tuckasegee River, though these differences decreased after dam demolition. 3 -17 All observed fish community metrics in 2008 indicated the fish assemblage at RM 31 8 (reservoir) was uncharacteristic of those occurring in nearby upstream and downstream riverine reaches, and was more consistent with the lentic habitat characterizing that dam - impacted site Dam demolition in early 2010 led to removal of a large portion of the lentic habitat at RM 31.8, though a submerged rock ledge resulted in a portion of this habitat persisting. Several fish community metrics at RM 31.8 were still atypical of those in nearby riverine reaches but the magnitude declined from 2010 to 2012; the trophic structure of the fish community appeared to change most rapidly. Mottled sculpin and two darter species were finally collected at RM 31.8 in 2012 Measured lengths of frequently caught Tuckasegee River fish species demonstrated growth and were typical for those species studied elsewhere in Tennessee and Virginia. 3 -18 Table 3 -1.
