Locust Fork (0316-0111) Sub-Watershed: Middle Locust Fork NRCS Sub-Watershed Number 050 Landuse: The Middle Locust Fork sub-watershed drains approximately 138 mi 2 in Blount and Etowah Counties. Land cover was forest with some pasture and crop lands. Three current construction/stormwater authorizations, 7 NPDES permits, and 13 CAFO registrations have been issued in the sub-watershed (Appendix B). Dry Creek is on ADEM’s 2002 §303(d) list for only partialy meeting its “Fish and Wildlife” water use classification. It is listed for several impairments caused by pasture grazing (Appendix C- 2). A 21.8 mile segment of Locust Fork is listed for siltation and other habitat alteration caused by agricultural runoff and abandoned surface mines (Appendix C-2). Graves Creek is impaired by organic enrichment/dissolved oxygen from pasture grazing and industrial sources. ADEM’s TMDL to reduce these polutants has been approved by EPA (Appendix C-1).

ADEM conducted NPS screening assessments of Dry Creek at DRYB-11 in 1997 and 2002 (DRYB-75a) (Appendix E, Appendix F). Habitat quality at Dry Creek was assessed as good (slightly impaired) during the 1997 and 2002 assessments (Appendix J, ADEM 1999a). Although instream habitat appeared to be stable and sediment deposition was limited, there was little riparian buffer remaining between the creek and pastures existing on both banks. Also, although fencing kept cattle out of the creek, grazing areas were located within the flood zone and below the high water mark of the creek. Six and 5 EPT families were collected at the site during 1997 and 2002, respectively, indicating the macroinvertebrate community to be in fair (moderately impaired) condition (Appendix K, ADEM 1999a). Intensive water quality data were collected from Dry Creek at DRYB-11 and DRYB-10 from January to September of 2002 (Appendix P-3). Dissolved oxygen concentrations were below the dissolved oxygen criteria of 5.0 mg/L at both sites during September of 2002. The pH at DRYB-11 was measured at 9.1 s.u. during June and July of 2002. Fecal coliform counts were >1,000 colonies/100mL in 12 (38%) of the 32 samples collected from Dry Creek. Fecal coliform counts were above the Fish and Wildlife water use classification criteria of 2,000 colonies/100mL during 3 (20%) of 15 sampling events at DRYB-11.
