Locust Fork (0316-0111) Sub-Watershed: Bristows Creek NRCS Sub-Watershed Number 020 Landuse: The Bristows Creek sub-watershed drains approximately 25 mi 2 in Etowah County. Land cover was mainly forest mixed with some crop and pasture lands. Eight current construction/stormwater authorizations, 2 mining, and one semi-public/private NPDES permits have been issued in the sub-watershed (Appendix B). Percent land cover estimated by local SWCD (Appendix A, ASWCC 1998) Forest Row crop Pasture Mining Urban Open Water Other 60% 14% 20% 2% 0% 1% 3% NPS impairment potential: Bristow Creek was identified as a priority sub-watershed in 1997 due to biological impairment at one site on Locust Fork (Shepard et al. 1997, ADEM 1999a). Based on the 1998 SWCD sub-watershed assessments, runoff from crop and pasturelands and septic tank failure were NPS concerns within the sub-watershed (Appendix D). Ratings for each NPS category based on values estimated during the SWCD sub-watershed assessment.

Assessment stations located within the sub-watershed. Descriptions are provided in Appendix E-1. Station GSA-26 Assessment Type Habitat, Biological, Chemical Date Location Area (mi 2 ) Classification 2002 Bristows Cr. at Pine Grove 20 F&W Bristows Creek: The substrate at Bristows Creek was composed of cobble, gravel, and sand (Appendix J). Habitat quality was assessed as good. Based on the results of ADEM’s screening-level assessment, the macroinvertebrate community was in fair condition (Appendix K). One-time water quality sampling conducted in June of 2002 showed elevated conductivity, alkalinity, hardness, total dissolved solids, and nutrients (NO 2 +NO 3 - N, TP) (Appendix M). Sub-watershed status: Bristow Creek was identified as a priority sub-watershed in 1997 and 2002 due to biological impairment at one site on Locust Fork (Shepard et al. 1997, 140
Locust Fork (0316-0111) ADEM 1999a). Runoff from crop and pasturelands and septic tank failure were NPS concerns within the sub-watershed. 141
