Box 241 Whittier, North Carolina 28789 17 June, 2003 Dowdle Mountain Mitigation Project Macon County DWQ # 981257 ~, 6'Olf Dear Mrs. Boaze: Thank you for the benthic macroinvertebrate monitoring report for the Dowdle Mountain mitigation project in Macon County. Our office received this report on May 30th. The report summarizes data collected prior to construction in 2000 and for two post construction sUrveys in 2001 and 2002 from a site on Queens Creek and three locations on the South UT. The report is well written; however, I do have some questions. o Are you aware of any appropriate regional reference information that might apply to these data? You note that there were no appropriate upstream reference reaches and current protocols for collection from DWQ were not formalized prior to construction. o You noted in the pre-construction section that there are two smaller tributaries of the Southern UT and that one carries a heavy sediment load. Were any restoration activities conducted on these features? o Your methods section notes that samples were collected from the upper fence line (fence), at a livestock crossing (crossing) and from below a culvert (culvert), but results listed in the benthos tables indicate that the data were collect in upstream to downstream order as fence, culvert and then crossing. Which is accurate? o You note that benthos data were collected during the pre-construction survey following two years of drought conditions. Do you feel that these drought conditions were responsible for the differences between communities at the 'fence' station and other locations (Le. many fewer taxa and lower abundance values)? o When was the construction begun and completed? Thanks again for this report. cc: Mike Parker, Asheville Regional Office Dave Penrose File Copy 1 Wetlands/401 Unit 1621 Mail Service Center Telephone 919-733-1786 An Equal Opportunity Affirmative Action Employer Raleigh, North Carolina 27699-1621 FAX # 733-9959 50% recycledllO% post consumer paper " State of North Carolina Department of Environment and Natural Resources Division of Water Quality James B.

The project involves the Little Tennessee River and three tributaries to /, f\ "" eJolf the Little Tennessee River - two unnamed tributaries (north and south UT) and Queens ,.~' Branch. The three tributaries meet the criteria of headwaters, i.e. less than 5 cfs aver~e t- <~F. annual flow. The drainage areas for the streams were 0.024 square miles for the north UT, 0.492 square miles for Queens Branch, and 0.206 square miles for south UT. ~ 'I j;;;. ;> , '. (pAr 1ll\ir Ad 0# +J..c-. . (ftj.:JlJ ~7 ' The project restor 900 liner feet (If) of stream. It Iso preserved and enhanced 2.39 acres of riparian b . ure 2). Historica this property has been agriculture, both cropland and pasture. The northern UT appeared to have been channelized and relocated during the period of agriculture land use. The three tributaries have been heavily impacted by grazing and direct access by cattle to the full length of stream beds. The south UT was also impacted by a direct sewage discharge from the house on the property. The restoration plan addressed the tour stream areas through rehydrating wetlands, restoring dimension and pattern to stream channels, fencing out livestock and planting riparian buffers. Preconstruction conditions can also be seen in the photographs of the project site (Appendix A).

The pre-c nstruction sampling preceded the guidelines required by NCDWQ, but fell wit' the techniques ofthe Qual- 4. Preconstruction samples were taken at four sites - 0 on Queens Branch at the livestock crossing, and three on the south VT (Figure 3 . The south VT was sampled at the upper fence line, at a livestock crossing mid-stream, and below a culvert as shown on Figure 3. No water quality measurements, pebble counts or cross section surveys were taken as the restoration preceded the benthic monitoring requirements from North Carolina Division of Water Quality in December 2001. Samples were sent to Pennington and Associates, Inc. in Coo keville, TN for the identification. Pre-Construction August 2000 11 ~/'ej? -{f-ir ;t ~ RESULTS AND DISCUSSION Degraded conditions were observed in all three stre from two smaller tributaries. one of which carried a eavv sediment load. There was 'significant bank erosion, channel widening from livestock access, and channel braiding. L'-' ~ residential sewage discharge occurred below the fence line site, bllt above the '-" \ crossing and culvert monitoring sites. This stream was heavily utilized by cattle for a .Q Ir' water and for cooling. Substrates were mainly silt, sand, and some gravel. Habitat was V{r mainly runs with some riflle and pool areas. The attached results show the pre-construction conditions on the three sampling reaches on south VT, and the sampling site on Queens Branch (Table 1). Queens Branch had fewer species, lower abundance and EPTs than the sites on the south VT. EPTs were present at all sampling sites. The most downstream site on the South VT exhibited the highest abundance and taxa ofEPTs. Tolerant species such as Oligo chaeta and f. Chironomidae were abundant, especially on the nutrient impacted south VT. t ...., Preconstruction conditions and during construction conditions are shown in attached '1 () 0 ouJ' pictures (Appendix A). The pre-construction sampling occurred during the second year/" tv of drought conditions in the region.

I ') r-- \ .~5 v ? ~v / The first sampling event occurred one year following construction. The sites, especially the south VT ones, still showed signs of impacts due to the restoration project with the number of organisms decreased considerably (Table 2). Most ofthe Diptera and O~ochaeta species had disappeared and the numbers dropped from abundant and ~ I common to rare. This was most likely due to the removal of the direct sewage outfall. C ~ Improvemem was observed on Queens Branch, where there was a decrease in the total ::;--- number of organisms, but an increase in EPT numbers and species. On the south VT, number of organisms and species decreased significantly. EPT taxa showed an increased abundance at the south VT fence site, but a decrease at the south VT culvert site and crossing site. Vegetation was becoming established throughout the riparian buffer ~ bank stabilization appeared to be in place. Live stakes and herbaceous vegetation did quite well, but many of the young trees were lost to drought. The sampling occurred during continued drought conditions in the region. Post Construction August 2002 Queens Branch results showed moderate gains over 2001, with the EPT counts remaining close to the same as 2001, and some increase in the number of species overall (Table 3). I ~7 All sampling sites on south VT continued to show improvement in the number of u ;I ~(,.r{ . organisms, species diversity, and especially EPT richness and abundance. It was no~ t that the increase also included Diptera species, but Chironomidae remained rar~e benthic community has responded well to the restoration project on the south VT despite the drought conditions and further improvements are expected when normal rainfall returns. Increased vegetation was observed in the photographs of the project site (Appendix B). A summary of the biological monitoring for the three years is included on T~k4. 5~ Future sampling Sampling at the four sites will continue through 2004. TABLE 2.
