The majority of the watershed lies within Ashe County, with the headwaters of the North Fork New River beginning in Watauga County and the headwaters of Big Horse Creek and Helton Creek beginning in Virginia. The North Fork New River flows in an east-northeast direction before it converges with the South Fork New River to form the New River. The land cover within this watershed is mostly forested (80%) with areas of agriculture (14%) and the least amount of developed land in the New River basin (3.7%). Rural residential properties and pasture lands are scattered throughout this watershed. Agricultural activities have historically consisted of pasture and cultivated croplands, but within the past 20 years has expanded to include Christmas tree farming. The majority of agricultural lands in this watershed are found along streambanks. Roughly 16,000 acres of conservation land are found in this watershed and include easements held by local watershed groups (Elk Knob State Park, Cherokee National Forest and Blue Ridge Rural Land Trust). This watershed’s population is centered mostly around the towns of Lansing and West Jefferson. Lansing’s population declined by 12% between 1990 and 2000, and was estimated to decline by another one percent by 2010 according to the 2000 census. West Jefferson’s population increased by 8% in 2000 and was estimated to increase by another 12% by 2010. 1.2 NC D W Q N E W R I V E R B A S I N P L A N : N oRth F oRk N EW R IV E R W AtER S hED hUC 0 5 0 5 0 0 0 1 0 1 2 0 1 1 FIgUR E 1 - 1 : N oRth F oRk N EW R IV E R W AtER S hED ( 0 5 0 5 0 0 0 1 0 1 ) "à)"à) "à) "à)"à)"à) "à) "à)"à)"à) "à) "à) "à)"à)"à)"à) "à)"à) "à)"à) "à)"à) "à) "à) "à) "à) "à) "à)"à) "à) "à) "à)"à) "à) "à) "à)"à)"à) "à)"à) "à) [¡ [¡[¡ [¡ [¡[¡ [¡ [¡ ¢¡ #* XY #* #* #* #* #* #* #* #* #* KB28 M i d dle ForkHC BigHorseCreek LongShoalsCr.

The large areas of forest and minimal agriculture and urban areas create only a minimal human impact to water quality. In DWQ’s efforts to protect the pristine nature of this watershed, a watershed-wide study was conducted to determine if these waters could be reclassified as High Quality Waters (HQW) or Outstanding Resource Waters (ORW). As a result, almost the entire watershed was reclassified as ORW. For a map of the affected area and a more detailed discussion see the Additional Studies section below. Little Buffalo Creek, near West Jefferson, is the only Impaired water body in the watershed and was not included in the reclassification. water Quality data suMMary For this watershed Monitoring stream flow, aquatic biology and chemical/physical parameters are a large part of the basinwide planning process. More detailed information about DWQ monitoring and the effects each parameter has on water quality is discussed in Chapters 2 and 3 of the Supplemental Guide to North Carolina’s Basinwide Planning document. uNderstaNdiNG the data Biological & Ambient Rating Converted to Use Support Category Biological (benthic and fish community) samples are given a bioclassification/rating based on the data collected at the site by DWQs Environmental Sciences Section (ESS). These bioclassifications include Excellent, Good, Good-Fair, Not Impaired, Not Rated, Fair and Poor. For specific methodology defining how these rating are given see Benthic Standard Operating Procedures (SOP) or the Fish Community SOP. Once a rating is given, it is then translated into a Use Support Category (see Figure 1-2). Ambient monitoring data are analyzed based on the percent of samples exceeding the state standard for individual parameters for each site within a two-year period. If a standard is exceeded in greater than 10.0% of samples taken for a particular parameter, that stream segment is Impaired for that parameter. The fecal coliform bacteria parameter is the exception to the rule. See the Fecal Coliform Bacteria section in the Ambient Data portion below. For the purposes of this plan, any site with greater than 7.0% to 10.0% of samples not meeting a parameter’s standard will be considered Impacted. Each biological parameter (benthic and fish community) and each ambient parameter is assigned a Use Support Category based on its rating or percent exceedance. Definitions for each category can be found in Use Support Methodology Chapter. Each monitored stream segment is then given an overall category which reflects the highest individual parameter category. For example, using the data from Figure 1-3, the individual parameter categories would be as follows: Benthos - 5, Fish Community - 1, Turbidity - 5. Therefore, the overall category, which is reported on the Integrated Report, would be 5 (Impaired). An Integrated Report is developed by the state every two years and reported to the U.S. Environmental Protection Agency.

During a three-week period in September 2004, the tropical storm remnants of Hurricanes Frances, Ivan, and Jeanne lead to wide-spread flooding throughout the central and northern mountains in the Catawba, French Broad, New, and Watauga River basins. Rainfall estimates for the combined three storms totaled more than 20-30 inches in certain watersheds. Runoff from the storms produced flash floods throughout the region, with peak flows in excess of 10,000 cfs (approximately 500 times median flows) in upper tributary streams; peaks flows in some tributary rivers exceeded 50,000 cfs. In the New River basin, the peak flow during Hurricane Frances (September 7th - 9th) was 14,700 cfs, which has an approximate recurrence interval of 10 to 25 years. During Hurricane Ivan (September 17th - 18th) the peak flow was 7,550 cfs, which has an approximate recurrence interval of 2 to 5 years. More detail about flows in the New River Basin can be found in the 2009 Basinwide Assessment Report: New River Basin produced by DWQ-Environmental Science Section. BioloGical data Biological samples were collected during the spring and summer months of 2004 and 2008 by the DWQ- Environmental Sciences Section as part of the five-year basinwide sampling cycle, in addition to special studies. Overall, 30 biological sampling sites were monitored within the North Fork New River Watershed. The ratings for each station can be seen in Appendix 1-B. Benthic Macroinvertebrate Sampling Each benthic station monitored during the current cycle is shown in Figure 1-5 and color coded based on its current rating. As seen on the map, the majority of samples taken in this watershed received an Excellent rating. This is reflected in the reclassification of almost the entire watershed to either High Quality Waters or Outstanding Resource Waters. The recent reclassification is discussed in more detail in the Special Studies in this Watershed Section below. As seen in Figure 1-6, 90% of the 30 sampling events received a Supporting rating and only 3% received an Impaired rating. These ratings are very similar to the previous sampling cycle. Figure 1-7 is a comparison of benthic site ratings sampled during the last two cycles to determine if there are any overall shifts in ratings. Eight percent of the samples improved their rating from the previous cycle and four percent declined in rating. Twenty-four percent of the benthic ratings had no change, indicating a semi-stable community.

Two of the sites were new monitoring sites located in rural watersheds with no NPDES dischargers. These sites were selected to determine their potential for becoming fish community regional reference sites. As shown in Figure 1-9, 60% of the five sampling events received a Supporting rating. Two of the samples were Not Rated; therefore, the segments are neither Impaired nor Supporting. Figure 1-10 is a comparison of fish community site ratings sampled during the last two cycles to determine if there are any overall watershed shifts in ratings. The community has remained stable with no change in ratings between the last sampling cycle and the current cycle.

One Ambient Monitoring System (AMS) station is located in the North Fork New River watershed (see Figure 1-1 for the station location). For more information about the ambient monitoring, parameters, how data are used for use support assessment and other information, see Chapter 2 of the Supplemental Guide to North Carolina’s Basinwide Planning. The ambient data are used to develop use support ratings biannually, which are then reported to the EPA via the Integrated Report (IR). The IR is a collection of all monitored waterbodies in North Carolina and their water quality ratings. The most current IR is the 2010 version and is based on data collected between 2004 and 2008. If a waterbody receives an Impaired rating, it is then placed on the 303(d) Impaired Waters List. The New River Basin portion of the 2010 IR can be found in Appendix 1-A and statewide on the Modeling & TMDL Unit’s website. Additional information about data from this cycle and seasonal variation in this basin can be found in the New River Basin Ambient Monitoring System Report. Long Term Ambient Monitoring The following discussion of ambient monitoring parameters includes graphs showing the median and mean concentration values for ambient station K7500000 in this watershed by specific parameter over a 13 year period (1997-2009). Each major parameter is discussed, even if no current impairment exists. The graphs are not intended to provide statistically significant trend information, but rather give an idea of how changes in land use or climate conditions can affect parameter readings over the long term. The difference between median and mean results indicate the presence of outliers in the data set. Box and whisker plots of individual ambient stations were completed by parameter for data between 2004 and 2008 by DWQ’s ESS and can be found in the New River Basin Ambient Monitoring System Report. pH AMS site K7500000 had no pH standard exceedances during this monitoring cycle, as shown in Figure 1-11 by a small green dot. Figure 1-12 shows the mean and median pH levels for all samples taken over the course of 13 years in the North Fork New River watershed. The pH pattern seen over these 13-years is a steady increase. This trend is seen in all three 10-digit watersheds in the New River Basin and is discussed further in the Executive Summary.

Possible sources of the elevated turbidity levels are discussed in the 12-digit subbwatershed section. Figure 1-14 shows the mean and median turbidity levels for all samples taken over the course of 13 years in the North Fork New River watershed. The yearly averages are well below the state standard of 50 NTUs, with the exception of the 2007 mean. There were a few turbidity samples measuring between 100 and 300 NTUs in 2007 that were not seen in any other year. While some erosion is a natural phenomenon, human land use practices accelerate the process to unhealthy levels. Construction sites, mining operations, agricultural operations, logging operations and excessive stormwater flow from impervious surfaces are all potential sources. Turbidity violations demonstrate the importance of protecting and conserving stream buffers and natural areas.

Figure 1-18 shows the mean and median of temperature levels for all samples taken over the course of 13 years in the North Fork New River watershed. The water temperature trend for this AMS station is closely linked to the stream flow levels. During low flow or drought periods, water can sit in small pools and become heated by the sun. This can especially be seen in Figure 1-18 between 2000 and 2002.

The FCB standard for freshwater streams is not to exceed the geometric mean of 200 colonies/100 ml or 400 colonies/100 ml in 20% of the samples where five samples have been taken in a span of 30 days (5-in-30). Only results from a 5-in-30 study are to be used to indicate whether a stream is Impaired or Supporting. Waters with a use classification of B (primary recreational waters) receive priority for 5-in-30 studies. Other waters are studied as resources permit. As seen in Figure 1-19, 20% of samples taken at station K7500000 during this cycle, resulted in levels over 400 colonies/100 ml. However, the geometric mean (calculated average) was 82 colonies/100 ml, indicating only pulses of elevated levels. When the geometric mean breaches 200 colonies/100 ml at a station, it is likely a 5-in-30 study would result in an impairment. Possible sources of the short term elevated FCB levels at this station are discussed in the subwatershed section. Figure 1-20 shows the geometric mean of FCB levels for all samples taken over the course of 13 years in the North Fork New River watershed. The geometric mean is a type of mean or average that indicates the central tendency or typical value of a data set. The highest yearly geometric mean for FCB was recorded in 2005 (125 colonies/100 ml). The figure also includes the yearly average stream flow, as seen in Figure 1-4, to show how flow can be closely linked to FCB levels. These slightly elevated FCB levels might have been caused by livestock with access to streams, failing septic systems or leaking municipal collection systems. For more specific information about AMS station K7500000 and its subwatershed see the subwatershed discussion below.

Six stream sites were selected for benthic sampling in addition to those sites already scheduled for sampling in the watershed for 2008. Reclassification of streams would lead to better protection of the high water quality exhibited in much of the North Fork New River Watershed. The watershed is home to the Kanawha Minnow (Phenacobius teretulus) which is listed as Vulnerable by the International Union for Conservation of Nature (IUCN), the Kanawha Darter (Etheostoma kanawhae) listed as Near Threatened by the IUCN, as well as many other endemic fish species. Study Results: Twenty-five benthic samples were collected from 24 sites in the North Fork New River watershed in 2008. Eleven of the 25 samples were collected as part of routine basinwide sampling that occurs every five years in the New River basin; seven were collected at the request of staff from DWQ’s Planning Section, WSRO, or Soil and Water Conservation for various studies; and one was collected as part of an internal quality assurance procedure. The remaining six samples were collected specifically to help support potential reclassification of waters in the North Fork New River Watershed. Data from all 25 samples were considered in this special study. Geographic data, habitat conditions, and physical and chemical water data are provided in the special study document. All but one of the 12 benthic sampling events at large-stream sites requested for special studies and nine of the eleven basinwide sampling events in the North Fork New River Watershed in 2008 resulted in classifications of Excellent. The two small-stream sites collected were assigned either Not Impaired or Not Rated (no DWQ criteria currently exist for classifying small-stream sites with drainage areas under 3.0 square-miles). All five benthic collections on North Fork New River proper, from the uppermost site near the headwater to the site furthest downstream one-quarter miles from the mouth, were among those resulting in classifications of Excellent. 1.11 NC D W Q N E W R I V E R B A S I N P L A N : N oRth F oRk N EW R IV E R W AtER S hED hUC 0 5 0 5 0 0 0 1 0 1 2 0 1 1 Recommendations for HQW status were based upon classification of Excellent following benthic sampling during 2008. ORW recommendations are based upon brook trout and hellbender records in addition to biological classification of Excellent. The recommendations were generated by the Environmental Science Section to the Planning Section within DWQ. The Planning Section examined other variables, held public hearings and based the final recommendation to the Environmental Management Commission (EMC) on all available information. Approval of Proposed Reclassification: In preparation of the reclassification, DWQ held a public meeting, reviewed public comments and worked closely with local governments and environmental groups. The National Committee for the New River (NCNR) was instrumental in helping DWQ spread the reclassification notice to the public and organizing the public hearings in the area. Local governments, NCNR and DWQ worked together to ensure the reclassification would sufficiently protected water quality and aquatic life while not placing an economical burden on local municipalities. The results of the public comments and meetings were all taken into consideration by the hearing officers and compiled into a collaborative conclusion to be finalized by the EMC. The reclassification was presented to the EMC in September 2010, and the rule went into effect December 1, 2010. The approved reclassifications can be seen in Figure 1-21. The majority of the North Fork New River Watershed received the ORW supplemental classification, which is shown in green on the map. Other portions of the watershed received the supplemental designation of HQW: Buffalo Creek; a portion of the North Fork New River from the confluence of Buffalo Creek to the confluence of Big Horse Creek; a portion of Big Horse Creek from the confluence of the North Fork New River to the confluence of Little Horse Creek; and Old Field Branch (Grass Branch). These HQW waters are shown in blue on the map. Claybank Creek and Little Buffalo Creek remain C Tr +, which is shown in yellow. Special Management Strategy (+) The “+” is a special management strategy that will comply with the HQW Rule (15A NCAC 02B .0224) to protect the excellent water quality downstream. Therefore, all waters designated as “+” in this watershed are regulated as if the waterbody was designated as HQW. ORW Designation The ORW supplemental designation does not allow any new NPDES discharges or expansion of existing discharges. It also requires more stringent stormwater management measures for development activities requiring sediment and erosion control plans (15A NCAC 02B.0225). HQW Designation The HQW supplemental designation does not permit single family discharges to surface waters, and any new or expanded dischargers must abide by more stringent waste treatment guidelines. More stringent stormwater management measures apply for waters that are draining to and within one mile of HQW waters (15A NCAC 02B.0224). 1.12 NC D W Q N E W R I V E R B A S I N P L A N : N oRth F oRk N EW R IV E R W AtER S hED hUC 0 5 0 5 0 0 0 1 0 1 2 0 1 1 FIgURE 1-21: NoRth FoRk NEW RIVER APPRoVED oRW & hQW RECLASSIFICAtIoN Ne w R i v e r N o r t h F o r k N e w R i v e r Je f f e r s o n We s t J e f f e r s o n La n s i n g Big L a u r e l C r e e k Littl e H o r s e C r e e k North Fork N e w R i v e r Mill Cre e k Sila s C r e e k Long H o p e C r e e k Hoskin Fo r k Stagg C r e e k Rich H i l l C r e e k He l t o n C r e e k B r u s h F o r k Piney Cree k Three Top Creek Big H o r s e C r e e k Buffalo Cr e e k Littl e L a u r e l C r e e k Kilby Creek Rou n d a b o u t C r e e k R i p s h i n B r a n c h J e r d B r a n c h Big Bra n c h R o a r i n g B r a n c h Little Phoe n i x C r e e k Los t B r a n c h Cab b a g e C r e e k Millpon d B r a n c h Doe Bra n c h Swift Branch Little Pin e y C r e e k Wa l l a c e B r a n c h Pr o p o s e d O R W w a t e r s h e d Pr o p o s e d H Q W "+ " a r e a Ex i s t i n g C : + Ex i s t i n g C ; T r : + Ex i s t i n g C ; T r , H Q W Mu n i c i p a l B o u n d a r y Ex i s t i n g H Q W Ex i s t i n g O R W No r t h F o r k N e w R i v e r O R W /H Q W R e c l a s s i f i c a t i o n As h e a n d W a t a u g a C o u n t i e s , N e w R i v e r B a s i n , N o r t h C a r o l i n a 0 1 2 3 4 0. 5 Mi l e s Ma p S o u r c e : N C D W Q , P u b l i s h e d 1 9 J u n 2 0 0 9 ; H y d r o g r a p h y S o u r c e : N C D W Q , P u b l i s h e d 3 0 N o v 2 0 0 7 Th i s m a p i s o n l y a s g o o d a s t h e d a t a a v a i l a b l e w h e n i t w a s p r i n t e d a n d i s n o t i n t e n d e d t o r e p l a c e a n y r u l e , r e g u l a t i o n o r c l a s s i f i c a t i o n s c h e d u l e .

The order of priority is not based solely on the severity of the steams impairment or impacts, but rather by the need for particular actions to be taken. A stream that is currently supporting its designated uses may be prioritized higher within this table than a stream that is currently impaired. This is based on a more wholistic evaluation of the drainage area which includes monitoring results, current and needed restoration/ protection efforts, land use and other activities that could potentially impact water quality in the area. Some supporting streams may have a more urgent need for protections than an Impaired stream with restoration needs already being implemented. The third and fourth columns of this table list potential stressors and sources that may be impacting a stream based on in-field observations, monitoring data, historical evidence, permit or other violations, and other staff and public input. In many cases, additional study is needed to determine exact source(s) of the impact(s). The last column includes a list of recommended actions. tABLE 1-1: PRIoRItIzAtIoN oF WAtERS IN thE NoRth FoRk NEW RIVER WAtERShED (hIghESt to LoWESt PRIoRItY) StREAm NAmE AU#CLASS.PotENtIAL StRESSoR(S) PotENtIAL SoURCE(S)StAtUS ACtIoNS NEEDED Little Buffalo Cr.10-2-20-1 C;Tr:+Habitat Degradation (Riparian Zones), Elevated Nutrients WWTP, Urban Runoff, Piped Streams, Agriculture Impaired RBR, WRP, DS, E, Ag, NMC Helton Cr.10-2-27 C;ORW;Tr Sediment, Elevated Nutrients, Over Stocking Agriculture, Logging Impacted SS, Protection (Hellbender Sal.)

Waterbodies discussed in this Chapter include all monitored streams, whether monitored by DWQ or local agencies with approved methods. Use Support information on all monitored streams within this watershed can be seen on the map in Figure 1-1, and a Use Support list of all monitored waters in this basin can be found in the Use Support Methodology Chapter. Use Support & Monitoring Box: Each waterbody discussed in the Status & Recommendations for Monitored Waters within this Watershed section has a corresponding Use Support and Monitoring Box (Table 1-2). The top row indicates the 2010 Use Support and the length of that stream or stream segment. The next two rows indicate the overall Integrated Report category which further defines the Use Support for both the 2008 and the 2010 reports. These first three rows are consistent for all boxes in this Plan. The rows following are based on what type of monitoring stations are found on that stream or stream segment and may include benthic, fish community and/or ambient monitoring data. If one of these three types of monitoring sites is not shown, then that stream is not sampled for that type of data. The first column indicates the type of sampling in bold (e.g., Benthos) with the site ID below in parenthesis (e.g., CB79). The latest monitoring result/rating of that site is listed in the next column followed by the year that sample was taken. If there is more than one benthic site, for example, on that stream, the second site ID and site rating will be listed below the first. The last row in the sample box in Table 1-2 is the AMS data. The data window for all AMS sites listed in the boxes in this Plan is between 2004-2008. Only parameters exceeding the given standard are listed in the second column with the percent of exceedance listed beside each parameter. Please note any fecal coliform bacteria (FCB) listing in the last row (as seen in Table 1-2) only indicates elevated levels and a study of five samples in 30 days (5-in-30) must be conducted before a stream becomes Impaired for FCB. tABLE 1-2: ExAmPLE oF A USE SUPPoRt AND moNItoRINg Box USE SUPPoRt: iMpaired (14 mI) 2008 IR Cat.4a 2010 IR Cat.4 Benthos (CB79) (CB80)Fair (2002)Fair (2002) Fish Com (CF33)Good-Fair (2002) AMS (C1750000) Turbidity - 12% FCB - 48% North Fork New river (NFNr) The North Fork New River flows through several 12-Digit subwatersheds. Each of the two segments are discussed below. North Fork New River [AU#: 10-2-(1)] The North Fork New River begins at the southern most tip of the Headwaters North Fork New River subwatershed (050500010103). The river flows 50 miles northeast, where it joins the South Fork New River to create the New River. This segment of the North Fork is approximately 14 miles long. Water Quality Status The most upstream site (KB141) was sampled in 2008 as part of the North Fork New River Sampling to Support Potential Reclassification special study. Details about that study can be found above. The river received an Excellent rating at this site; however, one bank was moderately eroded. A large portion of this drainage area is forested, with some agriculture along the stream banks.

The last sample taken at this station was in 1998. Results of both samples were very similar and included intolerant cool and cold water species indicating little to no change in water quality over the past ten years. Recommendations Protection efforts should be taken for this section of the North Fork New River to ensure the continuation of good water quality. North Fork New River [AU#: 10-2-(12)] This segment of the North Fork New River stretches over 36 miles across three different subwatersheds (Upper North Fork New River: 050500010106; Middle North Fork New River: 050500010107; and Lower North Fork New River: 050500010109). Land use along this segment is a mixture of agriculture along the stream banks, forest and a few scattered urban residential and commercial areas. Water Quality Status A benthic site (KB23), located just downstream of Three Top Creek, was sampled in 2008. This basinwide site has been sampled four times since 1993 and has consistently received an Excellent rating. The latest sample showed no impacts to the river’s stable macroinvertebrate community and received a high habitat score. The second benthic monitoring station (KB27) is located at SR-1644 (McNeil Rd), just before the river crosses into the Middle North Fork New River subwatershed (050500010107). The site has been monitored and rated Excellent every cycle since 1993, including 2008. Even though the habitat score for this site was low (65 out of 100) due to low quality riparian buffers, there is a healthy and stable benthic community. Helicopsyche paralimnella was found for the first time at this site in the 2008 sample. This taxa has only been collected at five other sites within the entire state by DWQ. This and other taxa collected indicate an absence of stressors and healthy water quality for aquatic life along this segment. The third site (KB135) is located at the Millpond Branch confluence where it received an Excellent rating in 2008. Due to difficult access, this site replaces the site about two miles upstream at NC-16, which has had a long history of Excellent ratings. Even though habitat was not ideal for aquatic life (65 out of 100), the benthic community is healthy and stable. The only AMS station in this watershed is located at the same spot on the river as benthic site KB135. Between 2004 and 2008, there were no major parameter exceedances; however, turbidity levels were elevated. Each parameter is explained in greater detail in the Ambient Data section above along with long term trends. The fourth benthic site (KB127) is about a fourth of a mile upstream from where the North Fork and South Fork merge into the New River [AU#: 10a]. This site was specifically monitored as part of the North Fork New River Reclassification Study which is discussed in greater detail above. The benthic community and habitat were very similar to the KB135 site just upstream and resulted in an Excellent rating as well. In September 2010, a survey was conducted to identify locations throughout the state where the Hellbender salamander is present. A population was found in the North Fork New River. More information about the Hellbender Salamander can be found on the NC National Heritage Program website.

There are no NPDES dischargers in this subwatershed and the majority of streams hold the secondary classification of Trout Waters. All streams in this 12-digit subwatershed drain to Three Top Creek. Three Top Creek [AU#: 10-2-13] Three Top Creek is approximately 13 miles from source to the North Fork New River [AU#: 10-2-(12)]. The majority of the drainage area is forested, with some areas of agriculture. Water Quality Status All streams in this 12-digit subwatershed drain to Three Top Creek. The stream was sampled for both benthic and fish communities during this cycle. Both sites are new basinwide sampling stations. The fish community sample contained a pollution intolerant population. The site was officially given a Not Rated due to absence of criteria for rating high gradient mountain trout waters. However, the combination of good habitat and a healthy stable fish population shows no indication of water quality issues. Two benthic samples were taken at the new monitoring station (KB138). The first sample was taken as part of the regular basinwide monitoring and received a Good rating. Biologists noted the sample may have been adversely affected by extreme low flow during a record drought at the time. The creek was part of the North Fork New River Reclassification Study (discussed above); therefore, the site was resampled to determine the bioclassification during normal flow level. The results of the July 2009 sample far exceeded the minimum requirements for an Excellent rating. In September 2010, a survey was conducted to identify locations throughout the state of the Hellbender salamander. A small population was found in Three Top Creek. Surveyors talked to local land owners who explained the population of the salamanders used to be much larger over ten years ago. This could be an indication of water quality impacts in the drainage area. Surveyors noted the stream was moderately turbid and the substrate was covered in silt at the time of sampling. More information about the Hellbender Salamander can be found on the NC National Heritage Program website. Recommendations Due to the presence of the Hellbender salamander, it is recommended that extra precautions be taken in this drainage area to prevent sediment from reaching the stream. Riparian buffers along this stream should be of adequate width and contain trees and shrubs. BiG laurel creek (050500010102) Includes: Big Laurel Creek [AU#: 10-2-14], Roaring Fork [AU#: 10-2-14-7], & Dixion Creek [AU#: 10-2-14-1] This subwatershed has mixed land use of forest and agriculture spread across the 29 square miles. Small Christmas tree farms are scattered across this area with larger tree farms in the northern headwaters. There are no NPDES dischargers in this subwatershed and the majority of streams hold the secondary classification of Trout Waters.

The source of the creek is located near Ivy Hill Road and Three Top Road, and is the collecting stream for all waters in this subwatershed. Land use in this drainage area is a mixture of forest and agriculture, with the majority of the agricultural lands lining the streambanks. Water Quality Status The creek was sampled for both benthic and fish communities about a tenth of a mile upstream of its confluence with the North Fork. All waters in this subwatershed pass through this point which gives a wholistic view of water quality for the subwatershed. The first set of samples taken during this cycle occurred in 2008, resulting in an Excellent benthic rating and a Good fish community rating. Both ratings were mimicked during the 2009 samples. Benthic samples from 1998 to 2008 indicate water quality slightly improving over the years. The fish station was a new basinwide site in 2008, and was noted as having a highly-diverse and trophically-balanced population. Aquatic habitat was over all in good condition with sufficient riparian buffers, but lacked riffle habitat and pool variety. Two Hellbender salamanders were collected during the fish community sample; one of adult age and the other young-of-year. The presence of this particular salamander and their age difference suggests high quality water. Recommendations Due to the presence of the Hellbender salamander, it is recommended that extra precautions be taken in this drainage area to prevent sediment from reaching the stream. Riparian buffers along this stream should be protected. headwaters North Fork New river (050500010103) Includes: North Fork New River [AU#: 10-2-(1) & (12)], Hoskin Fork [AU#: 10-2-7], Brush Fork [AU#: 10-2-8], Rock Creek [AU#: 10-2-9] & Roundabout Creek [AU#: 10-2-10] This subwatershed has mixed land cover of forest and agriculture spread across the 42 square miles. As seen in much of the New River Basin, agricultural lands are mostly located along the banks of major creeks. There are no NPDES dischargers in this subwatershed and the majority of streams hold the secondary classification of Trout Waters. North Fork New River [AU#: 10-2-(1) & (12)] Two segments of the North Fork New River flow through this subwatershed. Water quality status and other information about the full length of the river is discussed at the beginning of this section. Hoskin Fork [AU#: 10-2-7] Hoskin Fork is roughly five miles from source to the North Fork New River [AU#: 10-2-(2)], mostly flowing parallel to NC-88. The land use is a mix of agriculture and forest. Water Quality Status The benthic station located below Wilson Branch has been monitored during each five-year cycle since 1993. Each sample taken since 1993 has received a higher score than the last, suggesting water quality is gradually improving. The 2008 sample resulted in an Excellent rating as it did in 2003.

As seen in much of the New River Basin, agricultural lands are mostly located along the banks of major creeks. There are no NPDES dischargers in this subwatershed and the majority of streams hold the secondary classification of Trout Waters. Middle Fork Little Horse Creek [AU#: 10-2-21-8-1] Middle Fork Little Horse Creek is approximately four and a half miles from source to Little Horse Creek [AU#: 10-2-21-8]. Land use in this drainage area is mostly forest, with some agriculture along the streambanks. Water Quality Status Middle Fork Little Horse Creek was monitored as part of the North Fork New River Reclassification Study. There are no historical data for the stream. The stream substrate was covered in sand and silt and banks had noticeable erosion. Vegetation in the riparian zones consisted of only grasses and had little to no tree canopy. Despite the habitat deficiencies, the site (KB121) was among the sites with the most diverse pollution intolerant benthic populations within the study. Because of the Excellent rating given, the stream was recommended for a reclassification to HQW. Results of that study and reclassification are discussed above. Recommendations Riparian buffer restoration is suggested for Middle Fork Little Horse Creek. Establishment of shrubs and trees within the riparian buffer zone will assist with stabilizing banks and reducing the amount of sediment that reaches the stream bed. Additional trees will also provide a shaded canopy, keeping the water temperature cooler to support local trout populations. Little Horse Creek [AU#: 10-2-21-8] Little Horse Creek is almost 11 miles from source to Big Horse Creek [AU#: 10-2-21-(7)]. This stream is the main receiving stream for this subwatershed. Land use is a mixture of forest in the head waters and agriculture along the streambanks. Water Quality Status Little Horse Creek has been monitored since 1998 just upstream on the Middle Fork Little Horse Creek confluence. In 1998 and 2003 the creek received a Good benthic rating and displayed a stable population. The 2008 sample increased a rating to an Excellent due to a more diverse community. A stonefly (Isogenoides hansoni), which has only been collected at 44 sites statewide, was present in the 2008 sample and had not been previously seen in this stream. However, despite the current rating, habitat at the site was not ideal for a thriving benthic community. The lack of riparian zone, canopy cover and root mats are likely limiting fauna. Also, a layer of sand and silt indicates erosion issues upstream. This sample was used for the North Fork New River Reclassification Study. Little Horse Creek was recommended to be reclassified as ORW. Results of that study and reclassification are discussed above. Recommendations In order to maintain the water quality in Little Horse Creek, DWQ recommends local agencies work with farm owners to install agricultural best management practices to reduce sedimentation and erosion.

There is one minor NPDES discharger in this subwatershed. Majority of streams in the subwatershed hold the secondary use classification of Trout Waters. The Town of Lansing is located in the southern portion. Big Horse Creek [AU#: 10-2-21-(7), (4.5) & (1.5)] Big Horse Creek is approximately 20 miles long from source to the North Fork New River [AU#: 10-2-(12)]. Shortly downstream of its source, the creek crosses the state line into Virginia for roughly two miles before flowing back into North Carolina. The creek is the major receiving stream of this subwatershed and provides a good representation of overall water quality for the area. Water Quality Status There is one benthic and one fish community basinwide sampling station on this creek, located just upstream of the North Fork confluence and downstream of the Town of Lansing. Both sites received relatively low habitat scores due to lack of pool variety and small riparian zones. The fish community received a Good rating and was noted as having a diverse and trophically-balanced community of cool and cold water fish species. The benthic sample resulted in an Excellent rating. This sample consisted of the most pollution tolerant taxa collected since sampling started at this site in 1993. However, many new taxa were collected and in greater abundance. An additional benthic sample was collected at SR-1365 as part of the North Fork New River Reclassification Study. The sample resulted in an Excellent rating. The first two segments within North Carolina [AU#: 10-2- 21-(1.5) & (4.5)] were recommended to be reclassified as ORW. Results of that study and reclassification are discussed above. Recommendations Riparian buffer restoration is recommended to increase tree canopy cover and to help filter pollutants in stormwater runoff. upper North Fork New river (050500010106) Includes: North Fork New River [AU#: 10-2-(12)], Rich Hill Creek [AU#: 10-2-15], Buffalo Creek [AU#: 10-2-20] & Little Buffalo Creek [AU#: 10-2-20-1] This subwatershed has mixed land use of forest in the headwaters, some residential and agriculture scattered in the headwaters and along streambanks. There is one major and four minor NPDES dischargers in this subwatershed. Majority of streams in the subwatershed, excluding the North Fork New River, hold the secondary use classification of Trout Waters. Majority of the Town of West Jefferson is located in the southeastern portion of this subwatershed. Rich Hill Creek [AU#: 10-2-15] Rich Hill Creek is approximately five miles from source to the North Fork New River [AU#: 10-2-(12)].

This site (KB86) was monitored once before in 1993; both events resulted in an Excellent rating. The stream was recommended for a reclassification to HQW. Results of that study and reclassification are discussed above. Little Buffalo Creek [AU#: 10-2-20-1] Little Buffalo Creek is approximately four and a half miles from its source within the Mt. Jefferson State Park, through the town of West Jefferson, to Buffalo Creek [AU#: 10-2-20]. Land use within this drainage area is a mixture of forest, agriculture, urban and residential. Portions of the stream that flow through urban areas of West Jefferson are piped underground. Little Buffalo Creek has been on the Impaired Waters List since 1998 when it was listed for impacts from urban runoff and municipal pretreatment. In 2006, impervious surfaces and the West Jefferson WWTP were added to the list of potential sources of impairment. Water Quality Status A benthic station (KB32) located at Doggett Road crossing has been sampled four times between 1993 and 2008, receiving either a Fair or a Poor rating each time. The site received a Fair rating in 2008, showing a slight increase in abundance and diversity from the 2003 Poor sample. Biologists noted each of the four samples greatly varied in types of taxa collected. High levels of specific conductivity indicate the presence of waterborne pollutants. The stream received a fairly low habitat score and portions of the stream not piped underground have little to no riparian zones. An unnamed tributary which drains the majority of West Jefferson merges with Little Buffalo Creek near the West Jefferson WWTP. Large portions of this stream are also piped under commercial areas of West Jefferson. The majority of the town’s stormwater runoff flows into this unnamed tributary with little to no natural filtering, such as a riparian buffer. There are many possible sources for this impairment which have varied over the years. The West Jefferson WWTP was noted in the previous basin plan as having several discharge permit violations. Between 2003 and 2005, the Town had a few violation causing issues, including discovering a local industry knowingly discharging mercury and cadmium into the towns collection system. After confirming with samples, West Jefferson worked with the WSRO to conduct an unannounced inspection resulting in further confirmation of the illegal discharging. The Town issued civil penalties and pretreatment permit resolving the problem. West Jefferson also had operational issues where they failed to properly remove and land apply solids. The WSRO took enforcement actions and held meetings with the Town. The Town responded by hiring a contractor and a new operator. Discharge from the facility has been considered outstanding by the WSRO since that time. However the facility remains a possible source of Little Buffalo Creek’s Impairment during this cycle. The WWTP will be removed as a possible source, providing the facility stays in good standing during the upcoming monitoring cycle. Another possible source of impact is urban stormwater runoff. Much of West Jefferson’s stormwater runoff drains into portions of the unnamed tributary which has been piped underground. Bypassing natural riparian buffer zones, which can absorb waterborne pollutants, the contaminated runoff has little to no opportunity to be filtered before reaching Little Buffalo Creek. This concentration of stormwater runoff can be toxic to aquatic life. Downstream of West Jefferson, land use transitions to pasture land and Christmas tree farms. Agriculture is often a source of excess nutrients if proper BMPs are not utilized. Nutrients were added to the list of possible causes of impairment in 2000.

Samples taken during the previous cycle were also impacted by a similar drought. The slight increase in bioclassification rating (Poor in 2003 to Fair in 2008) indicates somewhat of an improvement in water quality. This is likely due to upgrades made to the WWTP, which can be seen in the few violations the facility received as compared to the previous cycle. Recommendations DWQ recommends developing a local stakeholder group to determine the possibility of day-lighting the full length of the creek. DWQ supports the need for funding a project of this nature that would include a Watershed Restoration Plan (WRP), as well as follow up monitoring. The WRP should also include planning for implementation of proper riparian buffers, determining the best locations for additional stormwater control measures and efforts to educate affected property owners and the local community about the purpose of this work. Buffalo Creek [AU#: 10-2-20] Buffalo Creek is approximately ten miles long from source to the North Fork New River [AU#: 10-2-(12)]. The drainage area consists of mostly forest with agriculture clustered along streambanks. Headwaters of Buffalo Creek and a few upstream tributaries are within the Bluff Mountain Preserve and Three Top Mountain Game Land. Water Quality Status In 2008, two benthic samples, including one above and below the Little Buffalo Creek confluence, were collected and rated as Excellent. The sample above Little Buffalo Creek (KB134) was collected as part of the North Fork New River Reclassification Study, with the purpose of assessing conditions in the catchment without the urban influence of West Jefferson. There was little difference between the two benthic sites. The downstream site (KB31) had a slightly higher specific conductivity and pH level, as well as a more pollution tolerant population. However, the site received a higher habitat score due to larger, more stable riparian buffers. A fish community sample (KF21) was also collected at the same location as the upstream benthic sample. This new basinwide site was given a Not Rated due to lack of criteria for high gradient mountain trout waters. This stretch of Buffalo Creek provides excellent habitat for a diverse and fairly trophic balance mix of cool and cold water fish. Fifty-nine percent of species collected were pollution intolerant, indicating the stream supports a reasonably healthy population and appears to have no obvious water quality issues. North Fork New River [AU#: 10-2-(12)] A portion of this segment flows through this subwatershed. Water quality status and other information about the full length of the river is discussed at the beginning of this section. Middle North Fork New river (050500010107) Includes: North Fork New River [AU#: 10-2-(12)], Little Phoenix Creek [AU#: 10-2-23] & Long Shoals Creek [AU#: 10-2-25] This subwatershed has mixed land use of forest in the headwaters, with some residential and agriculture scattered in the headwaters and along streambanks. There is one minor NPDES discharger in this subwatershed. Majority of streams in the subwatershed, excluding the North Fork New River, hold the secondary use classification of Trout Waters. Long Shoals Creek [AU#: 10-2-25] Long Shoals Creek is approximately three miles long from source to the North Fork New River [AU#: 10-2-(12)].

The site KB123 is located a mile upstream of the confluence with the North Fork New River and had overall good habitat; however, pools were infrequent and filling with silt and sand. The stream’s drainage area is less than 3.0 square miles. The site would have received a classification of Good if criteria for larger stream sites were used. Because, criteria for small streams are still in development, the site is currently classified as Not Impaired. Recommendations The benthic site is located just upstream from its confluence with Foster Springs Branch [AU#: 10-2-25-1] and therefore does not reflect influences from that drainage area. An additional site will be considered on Foster Springs Branch for benthic sampling to assess conditions prior to further development (DWQ, B-20081007). If resources are limited, DWQ will consider moving the current site below the confluence. Little Phoenix Creek [AU#: 10-2-23] Little Phoenix Creek is approximately five miles long from source to the North Fork New River [AU#: 10-2-(12)]. The drainage area consists of mostly forested area with agriculture and residential areas clustered along streambanks. Water Quality Status A one time benthic sample was taken in June 2008 to determine if upstream land clearing activities in 2006 had any long-term impacts on the community downstream. The site was given an Excellent bioclassification and had no signs of impacts from sediment on the benthic community. However, the site was somewhat deficient of available macroinvertebrate habitat, pool frequency and riparian zone condition along one bank. (DWQ, B-20081007) DWQ Special Study (B-20070904): Approximately 85 acres of land in the headwaters of the unnamed tributary (UT) had been cleared for planting of Christmas trees and pasture in 2006. The resulting runoff from the steep slopes of the cleared land had caused extreme scouring of the UT, resulting in large rocks blocking a downstream culvert over a driveway. This caused flooding and sediment deposition on the property of the downstream landowner. DWQ took benthic samples at two locations to determine the water quality impacts of this land clearing activity. One sample location was just below the impacted area and the second site was located on a comparable site draining to the opposite side of Little Phoenix Creek. The impacted sampling site (KB117) was a little over a tenth of a mile upstream of the culvert, in a heavily wooded area. Massive rocks and other debris had been washed downstream and extreme scouring, roughly five meters in height, can be seen in photos taken by biologists in the special study document. The stream wetted width was about one meter where as the channel had been scoured out to four and five meters wide. The habitat still received a relatively good score (78 out of 100); however, the bottom substrate consisted of bedrock, boulders, rubble, no leaf packs and exposed tree roots. The control site (KB118) had similar slope and substrate as the impacted site. However, K118 had no scouring and a channel with similar width as the streams wetted width (one meter) and included leaf packs and other characteristics of a small mountain stream. Sample results from KB117 indicated the majority of the benthic community had been washed away. Only 24 total individual organisms were found at the site and none of the taxa were found in abundance. However, the control site, had 36 total taxa that were found to be in abundance. The majority of these diverse taxa were intolerant species, commonly found in small mountain streams. The study indicated a devastating impact to the benthic community due to the recent complete rearrangement of the stream bed and the extreme streambank erosion from unusually high flow levels. Recovery of the impacted UT will be slowed by the fact that the entire stream, including the headwaters, have been scoured.

UT Little Phoenix Creek Stream Restoration & Success Story: In 2007, the National Committee for the New River (NCNR) was awarded a Federal 319 Grant in the amount of $65,400 for restoring an unnamed tributary to Little Phoenix Creek (Figure 1-22). The purpose of this project was to repair 315 feet of a UT- Little Phoenix Creek which was severely damaged by excessive flooding as the result of upstream land clearing activities. The stream restoration was based on natural channel design concepts. Rock step-pool structures were installed in the impacted reach and streambanks reshaped to the proper profile. Once the work was completed, native riparian vegetation was planted along the streambanks to aid in bank stability and to lessen the impacts of thermal pollution on this small headwater stream. 1.24 NC D W Q N E W R I V E R B A S I N P L A N : N oRth F oRk N EW R IV E R W AtER S hED hUC 0 5 0 5 0 0 0 1 0 1 2 0 1 1 An existing culvert was removed since it acted as a dam, interfering with proper sediment transport. A bridge that spans the entire flood plane was built that allowed the stream profile to be maintained through the reach. The goal of the project, to stabilize the lower reach of UT Little Phoenix Creek at the property, was met. DENR officials worked with the landowner at the top of the mountain to stabilize the 85 acres that had been cleared. NCNR worked with both upstream and downstream landowners to develop and implement a site plan. The result is a functional, stable stream that is also attractive. See the project’s Final Report for more detailed information about the purpose, restoration details and final results. heltoN creek (050500010108) Includes: Helton Creek [AU#: 10-2-27] This subwatershed has mixed land use of agriculture, some residential and forest in the headwaters. There are no NPDES dischargers in this subwatershed. Majority of streams in the subwatershed hold the secondary use classification of Trout Waters. Helton Creek [AU#: 10-2-27] Helton Creek is approximately 19 miles from the NC/ VA state line to the North Fork New River [AU#: 10- 2-(12)]. This is the main receiving creek for this subwatershed. Land use is a mixture of mostly forest on the south side of the stream and agriculture and residential on the north side. Water Quality Status Helton Creek was monitored at four biological sites during 2008 and 2009. Five benthic samples were taken at three locations along the creek. Two of the three sites were sampled for purposes of a special study. The most downstream benthic site (KB25) is a basinwide site and has been sampled since 1998. Each sample since 1998 has resulted in an Excellent rating, indicating the stream has a stable benthic community. The rating at this site dropped to a Good when it was sampled a second time in 2008 and maintained that Good rating when sampled again in 2009. The fish community site, which is in the same location as KB25 and is a fish community reference site, was monitored in 2008 and received a Not Rated. This rating was given due to unexpected nature of the number and the type of species collected until further sampling could be completed. None of the trout species were native or wild and all appeared to be stocked. The 2009 sample showed similar results and was rated Good- Fair. The large number of stocked species is either an indication of nutrient inputs upstream from nonpoint sources, or the managed trout fishery is affecting the natural fish predators so that prey species are not being controlled. The specific cause of the drop in rating is not known at this time and the stream is considered to be impacted. In September 2010, a survey was conducted to identify locations throughout the state of the Hellbender salamander. A population was found in Helton Creek. More information about the Hellbender Salamander can be found on the NC National Heritage Program website. DWQ Special Study - Helton Creek (B-20081202): A request for benthic sampling was received from the WSRO for three sites on Helton Creek in Ashe County. Sediments from logging, farming, and other agricultural activities in the watershed have filled in the stream above a small low-head dam upstream of SR 1526/Ashe County (KB136), causing a shift in the stream channel. The banks of the new channel are unstable and are a source of additional sediments to the stream. Benthic sampling was requested to assess potential effects of the sediments on the benthic community.

The quarter mile segment of Helton Creek where the stream channel had shifted is located just above the middle site (KB136) and is the source of increased sedimentation. One site was selected upstream of the altered channel, one directly downstream, and a third site near the confluence with North Fork New River. The two upstream sites rated Excellent and the downstream site rated Good. It was concluded that the benthic data did not indicate impacts to the benthic community downstream of the new channel. A more detailed summary of the biological data and resultant bioclassifications can be found in the Special Study document. Recommendations A stressor study is recommended to determine the source of the large amount of stocked fish. lower North Fork New river (050500010109) Includes: North Fork New River [AU#: 10-2-(12)] & Millpond Branch [AU#: 10-2-28] This subwatershed has mixed land use of forest in the headwaters, some residential and agriculture scattered in the headwaters and along streambanks.

A few EPT taxa were collected for the first time, including: Acroneuria carolinensis, Hydroptila, and Nectopsyche exquisita . Data Analysis The site is 8.2 miles west of Jefferson. This is the site furthest upstream of the three basinwide sites on North Fork New River. The site has consistently received classifications of Excellent following each summer sampling event (a Good was received after a non-summer sampling event in March 1989). No indications of impact are exhibited by the benthic community.

Helicopsyche paralimnella has been recorded for the first time from the site; this is only one of five sites in the state so far at which the species has been found by BAU, though undoubtedly more sites will be found. Data Analysis The site is 4.6 miles NNW of Jefferson and is directly upstream of the mouth of Big Horse Creek. The town of West Jefferson is almost entirely included in the catchment above the site. Consistently high EPT Richness and low NCBI values have resulted in classifications of Excellent for each sampling event between 1993 and 2008. The healthy benthic community indicates an absence of stressors at the site.

However, there were a few EPT taxa collected at Old NC 16 that have not been collected at NC 16 over eight sampling events, including (all rare within the sample except as noted): Acerpenna pygmaea, Heterocloeon anoka (common), Anthopotamus distinctus, Agnetina, Hydroptila,and Pycnopsyche lepida group. Data Analysis The site is 7.4 miles northeast of Jefferson and six stream-miles above the confluence with South Fork New River. This is the furthest downstream site of the three basinwide sites on North Fork New River. The town of West Jefferson is almost entirely included in the catchment above the site. This site replaces the basinwide site at NC 16, which is about two stream-miles upstream of this site, due to difficult access to the river at NC 16. The four summer sampling events in 1989, 1993, 1998, and 2003 resulted in classifications of Excellent at the former basinwide site. There appears to be little difference in water quality either temporally or longitudinally between sampling events on this lower segment of North Fork New River.

A few taxa were collected for the first time at the site, including: Ephemerella subvaria, Serratella deficiens, Hexagenia, Acroneuria carolinensis, and Leucotrichia pictipes. Data Analysis The site is about 1.5 miles east of the closest point on the Tennessee Valley Divide and 0.8 stream-miles from the confluence with North Fork New River. Increasing EPT richness with each successive sampling event since 1993 is suggestive of improving water quality at the site.

There are no historical data for the site, so trends in community composition can not be analyzed. A few taxa were collected here that have not been collected at the former basinwide site downstream, including: Procloeon, Maccaffertium pudicum, Diplectrona modestum, Ceraclea, and Chimarra. Data Analysis The site is 8.1 miles west of Jefferson. This new basinwide site is 1.3 stream-miles upstream of the former site at SR 1100. The site was moved to remove the influence of development directly upstream of the old basinwide site, and to locate it in the Amphibolite Mountains ecoregion so that a potential reference site for the ecoregion could be established. The same number of EPT taxa were recorded for this site in 2008 as were for the former site in 2003. In both cases the additional of a single EPT taxon would have resulted in a classification of Excellent.

Baetisca berneri, a mayfly often collected in the New River basin but uncollected at the prior basinwide site on Buffalo Creek, was abundant at this site. The low EPT BI indicates a community intolerant to the presence of pollutants. Data Analysis The site is about 2 miles west of Jefferson. The basinwide site for Buffalo Creek was relocated to above the mouth of Little Buffalo Creek to assess conditions in the catchment without the influence of West Jefferson WWTP; the original basinwide site is about 0.4 stream-miles downstream of the present site. At the new location the catchment is mostly forest and pasture with no urban influence. The high EPT Richness and low EPT BI value indicates a healthy benthic community and the absence of stressors.

Even for the two sampling events with similar EPT richness (1998 and 2008) only four taxa were in common. In 2008 four EPT taxa were collected that had not been collected during prior sampling events, and three of those (Maccaffertium pudicum, Hydropsyche betteni, and Leucotrichia pictipes) were abundant in the sample. Data Analysis The site is one mile west of downtown Jefferson and within 0.9 stream-miles downstream of the West Jefferson WWTP. The stream is on the state's 303(d) list for nutrients and impaired biological integrity. For the four sampling events since 1993 the lowest NCBI value is shown for 2008, and EPT Richness is close to the high value from 1998. Of the four years that benthic sampling was performed 2008 exhibited the lowest flows for area streams. Dry conditions should increase instream effluent concentrations from the WWTP upstream; the benthic community does not reflect this.

Many taxa were recorded for the first time, including:Brachycercus, Dannella simplex, Ephemerella dorothea, Eurylophella aestiva, Rhithrogena uhari, Ceraclea enodis, and Neophylax fuscus. There were several highly tolerant taxa (i.e. with a tolerance value of 8.0 or greater) either common or abundant that helped to drive the NCBI value up: Corixidae; the midges Chironomus, Polypedilum illinoense group, Procladius, Thienemannimyia group; and Nais , an oligochaete. Data Analysis The site is about 4.7 miles NNW of Jefferson and about 0.25 stream-miles above the confluence with North Fork New River. The site has received a classification of Excellent during each summer sampling event since 1993, in most cases driven by high EPT abundance and richness.

Isogenoides hansoni was identified from the site for the first time in 2008; this is one of 44 sites from which the BAU has collected the stonefly. Leptocerids have not been collected from the site, reflecting the paucity of root mat habitat. Data Analysis The site is about 9.7 miles northwest of Jefferson and 3.6 miles south of the Virginia border. The site attained a classification of Excellent for the first time in 2008. Though the benthic community does not reflect stress, the lack of a riparian zone at the reach sampled is likely limiting the fauna. A canopy over the stream would increase the presence of coldwater stenotherms, root mats provided by trees would diversify benthic habitat, and streamside vegetation would filter pollutants from runoff.

The only leptocerid collected during summer sampling was Setodes (rare in the sample) in 1998, reflecting the paucity of root mats at the site.Glossosoma, which was abundant in 2003, was uncollected in both 1998 and 2008. Otherwise the EPT portion of the benthic community was similar among the three summer sampling events at the site, primarily with taxa rare at the site dropping in and out. Data Analysis The site is 8.4 miles NNE of Jefferson, and 1.7 stream-miles from the confluence with North Fork New River. There has been little change in the benthic community among the three summer sampling events, suggesting stable conditions at the site since 1998.
