Of the monitored CO UNTIES lakes, 37 percent are also impaired. These impairments closely follow population Cabarrus, Davidson, Forsyth, and land development patterns. Habitat degradation is the stressor that accounts Guilford, Montgomery, Rowan, for the largest percentage of stream impairments, while nutrient enrichment is Randolph, Stanly negatively impacting the lakes. A major study is underway to develop a total maximum daily load for High Rock Lake to identify possible nutrient reduction MUNICIPALITIES actions. High Point, Thomasville, Randleman, Lexington, Spencer, GENERAL DESCRIPTI O N East Spencer, Salisbury, Granite Quarry, China Grove, Rockwell, The Yadkin River Watershed is roughly bounded on the north by High Point, Denton, Asheboro Thomasville, Lexington and Salisbury. The drainage contains High Rock Lake, Tuckertown Reservoir, and Badin Lake. Major tributaries include Abbotts Creek PER M ITTE D FACILITIES and the Uwharrie River. Much of the eastern portion drains the relatively NPDES WWTP: undeveloped area forming the Uwharrie National Forest. Most of the streams in Major 10 this watershed are located in the Carolina Slate Belt portion of the piedmont Minor 39 ecoregion. These streams usually have a rocky substrate and may experience very NPDES Nondischarge: 22 low flow during drought conditions. Agricultural land use affects most streams NPDES Stormwater: outside of the urban areas. General 184 Individual 11 The Abbotts Creek watershed starts just south of Kernersville and flows south Phase II 6 through Lexington and empties into High Rock Lake. Smaller streams in the Animal Operations: 42 watershed are Rich and Hunts Forks and Swearing and Hamby Creeks, which drain High Point, Thomasville, and the west side of Lexington. This watershed is located STREA M SU mm ARY primarily in Davidson County and is bisected by the industrial and commercial US Total Streams:..............787mi 64 and I-85 corridors.

The lower portion of the watershed, in southern Randolph and northwestern Montgomery counties, is within the Uwharrie National Forest. Most of the subbasin is forested or used for agriculture. The Uwharrie River is within the piedmont Carolina Slate Belt ecoregion, but some tributaries draining the Uwharrie Mountains have montane characteristics. Certain geological subdivisions of the Carolina Slate Belt appear to have ecological significance. The sandiest streams were observed in the northern portion of the subbasin. More rocky streams were observed in the southern portion of the watershed. 1 NC DWQ YADKIN - PEE DEE RIVER BASIN PLAN Yadkin River HUC 03040103 2008 2 F I XY G ¡[)"à URE )"à¡¢ #0 )"à)"à*# # ¡[ )"à * )"à )"à *## ")¡¢à )"à * )"à)"à )"à ¡[ Yadkin - Pee Dee River Basin *# )"à 3-1. )"à)"à *# )"à *# )"à)"à ¡¢ )"à )"à )"à # #0 )"à #0*##**# ¡[ *#¡[ Yadkin River Watershe*#d #**#0*#*#*#*# *# )"à )"à * *# ¡[ ¡[)"à *# ¡[)"à )"à)"à #0 ¡¢¡[ 8-Digit HU%2C 030¡¢ 40103 ¡¢ ¡[ Y #*0 ¡¢ )"¡¢à *# A FORSYT#H ¡[)"à )"à#0 ¡¢ XY * *# D N *# )"à¡¢ KIN )"¡[à C )"à ¡[ *# )"à¡¢ - #0 *# *# *# 1 XY 0 #0 XY ¡[ *# *# 9 )"à # 0 ¡[ "à R )"à ))"à # *# ¡[)"à %2 *# k*# *# )"à )"à * e )"à IVER )"à Cre )"à )"à¡¢ )"à ¡[)"à #0*# tts High Point *# o )"à¡¢ ¡[ )"à ¡¢ *# b ¡[¡¢ ¡¢ b ¡[)"à )"¡[àXY )"àXY¡[)"à )"à XY #A ¡[ 0 )"à ¡¢ )"à #0 HUC *# #0 ork )"à *# nts F k u )"à r H )"à *# o)"¡¢à )"à)"à)"à *# F #0 *# ¡¢ h Thomasville *# ic #0 ¡¢*# " R)"à #0 )"¡[à 03040103 )à %2 #0 )"à )"à *# *# )"à¡¢ )"à *# )"à *# " *#)"à )"¡¢à )"à¡¢ )à )"à )"à)"à¡¢ Trinity k "à"à )"à XY Legend e )"à )) )"à *# )"à e ")à ¡[)"¡¢à r ¡¢¡[)"à ek *# C H )"à re *# a C r ¡¢ Monitoring Stations )"à g Lexington mb y e n iv i r ")à "à XY ¡¢ *# R ¡[ ¡[) )"àa e e i Fish "à )"à k ) r e *# w )"à¡¢ r a )"à ¡¢ S I-85 )"à e #* h r )"à * w ¡¢ [)"¡¢à )"à)"à )"¡[à #0 # C 0 U Ambient ¡¢ XYk "à ¡[)"à # e ) y0 )"à )"à ¡[ ")à )"à e DAVIDSON US-64 a *# r w ")à C ¡¢ a )"à *# *# ar Benthos XY s C *# t *# )"à¡¢ *# t *# *# )"à ¡¢ o *#)"à¡¢ b NPDES Non Discharge Permits *# *# XY b ¡[)"à *# ¡¢ #0 XY A XY )"à %2 ¡[)"à¡¢ ¡[¡[ ")à Major NC Asheboro *# )"à¡[)"à -4 )"à Salisbury ¡¢)"à 7 *# )"à #0 Minor ¡¢ #0 NC-8 k %2 e ¡[ e *# # NPDES Discharger Permits r )"à )"à *¡¢ )"à )"à )"à C # *# 0 High Rock Lake ek )"à Denton s k e *# t e r XY )"à )"à )"à e C Major n r ¡¢)"à )"à a C k %2¡[ "à r ic )¡[ G *# n *#¡¢# L ¡[)"à w ROWAN * k *# o Cree Minor T in"à )"à b ) Ca RANDOLPH *# #0)"à )"à ¡[ ¡[ Aquatic Life Rating )"à Rockwell ")à )"à #0 YA )"¡[à )"à D ¡[ Impaired )"à)"à ¡[)"à k K "à)"à e IN ) Cre Second R I No Data *# V *# )"à #0 *##0%2 E *# R ")à Not Rated *# *# %2 #0Richfield %2 "à )"à ¡[)"à MONTGO)MERY Supporting STANLY Tuckertown Lake )"à #0 )"¡[à #0 )"à # #0 )"à ¡[)"à 0 *# )"à)"à¡¢ )"à )"à Primary Roads ¡[ )"à *# )"à *# *# )"àXY Municipality Boundary *# *# *# )"à )"à ¡[ )"à ¡[ ¡[)"à )"à¡¢ ")à )"à ")à ¡¢ )"à ® )"à ¡[ County Boundary ¡[¡¢ *#")à ¡¢ ¡¢ ¡[)"à 0 3 6 ¡[ 12 )"à ¡[)"¡¢à DWQ Planning Section )"à ")à # 8-Digit HUC Boundary ¡[ ¡¢ Miles Basinwid*e Planning Unit ¡[)"à )"à XY )"à¡¢ ¡¢ ¡[ July, 2008 XY ")à XY )"à ¡[ ¡[)"à CURRENT STATUS AN D SIGNIFICANT ISSUES Impaired streams are those streams not meeting their associated water quality standards in more than 10 percent of the samples taken within the assessment period (January 1, 2002 through December 31, 2006) and impacted streams are those not meeting water quality standards in 7 to 9 percent of the samples. The Use Support report provides information on how and why water quality ratings are determined and DWQ’s “Redbook” describes in detail water quality standards for each waterbody classification. For a general discussion of water quality parameters, potential issues, and rules please see “Supplemental Guide to North Carolina’s Basinwide Planning: Support Document for Basinwide Water Quality Plans” Figure 3-1. shows monitoring station locations and impaired streams for the Yadkin River subbasin. Appendix A. provides descriptions of all monitored waterbodies in the subbasin. Appendix B. provides a summary of each ambient data monitoring station. Appendix C. provides summaries of biological and fish assessment monitoring sites. River HUC 03040103 2008 Yadkin - PEE DEE RIVER BASIN PLAN YADKIN NC DWQ General Biological Health Fourteen sites were sampled for benthic macroinvertebrates in this HUC in 2006 (Figure 3-1). Among these, four sites (Grants Creek, Swearing Creek, Little Uwharrie River, and Uwharrie River at SR 1406) showed improved bioclassifications compared with 2001 sampling, seven sites retained the same bioclassification as 2001, and two sites (Lick Creek and Uwharrie River at SR 1143) showed degraded bioclassifications compared to 2001. Dutchmans Creek, not rated in 2001 was rated Excellent in 2006. None of the sites improved or degraded more than one level of bioclassification. Eleven sites were sampled to evaluate fish populations. No site showed an improved bioclassification, three sites retained their 2001 classification, and three sites (Cabin Creek, Rich Fork,Abbotts Creek) showed degraded classification compared to 2001. Five additional fish sites were sampled for the first time in 2006. Leonards Creek (Davidson County), previously sampled as a basinwide site was not sampled in 2006 due to low flow conditions. Similarly, Rich Fork at Davidson County SR 2005 was not sampled for benthos during 2006 due to excessive depth caused by operations of sand-dipping operations. It is likely that the latter site will therefore be discontinued. FI G URE 3-2.
