Lower Black Warrior River (0316-0113) Assessment stations located within the sub-watershed. Descriptions are provided in Appendix E-1. Station Assessment Type Date Location Area (mi 2 ) Classification BPRH- 44a BPRH- 44b BPRH- 44d COTH- 57c None conducted Habitat, Biological, Chemical Habitat, Biological, Chemical Habitat, Biological, Chemical 2002 Dry Cr. at AL Hwy 61 24 F&W 2002 Big Prairie Cr. at Perry CR 20 32 F&W 2002 Big Prairie Cr. at AL Hwy 25 100 F&W 2002 Cottonwood Cr. at Hale CR 12 42 F&W Cottonwood Creek: At COTH-57c, Cottonwood Creek was a low-gradient, clay, gravel, and sand-bottomed stream located in the Blackland Prairie (65a) subecoregion (Appendix J). Water quality at the site was severely impacted by permitted runoff from land application activities upstream of the sampling reach (ADEM in house memo). One-time water quality sampling was conducted at COTH-57c on May 8 th of 2002 (Appendix M). The dissolved oxygen concentration was measured at 2.2 mg/L. Nutrient concentrations were very high (NH 3 -N=7.0 mg/L; TKN=7.4 mg/L; TP=2.1 mg/L, DRP=0.5 mg/L). Conductivity, total dissolved solids, alkalinity, and hardness were also elevated. Habitat quality was impaired from heavy sedimentation, poor instream habitat, and eroded banks. Algal mats and decaying algae were common at the site. No EPT families were collected, indicating the macroinvertebrate community to be in very poor condition (Appendix K). Sub-watershed status: The fish community was assessed as poor at one location on Big Prairie Creek. The condition of the macroinvertebrate community was assessed as good at a 2 nd location, but total suspended solids, chlorides, and nutrient concentrations (TKN, NO 2 +NO 3 -N, DRP) were elevated at one location on Big Prairie Creek. Fecal coliform concentrations were >780 colonies/100mL of surface water. Water quality at one site on Cottonwood Creek was found to be severely impacted by permitted runoff from land application activities upstream of the sampling reach. Habitat quality was also impaired from heavy sedimentation, poor instream habitat, and eroded banks. 186
Lower Black Warrior River (0316-0113) Sub-Watershed: Little Prairie Creek NRCS Sub-Watershed Number 170 Landuse: The Little Prairie Creek sub-watershed drains approximately 96 mi 2 in Hale County. Land cover within the sub-watershed was predominantly pasture. One semipublic/private NPDES permit has 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 5% 15% 75% 0% 5% 0% 0% NPS impairment potential: The potential for impairment from aquaculture and pasture runoff was high. There was a moderate potential for impairment from cropland runoff. Little Prairie Creek was given a 2 nd priority sub-watershed rating by the local SWCD for resource concerns including excessive erosion of crop and agricultural lands, and roads/ roadbanks, overgrazing of pastures, and cattle in streams (Appendix I). 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 Assessment Type Date Location Area (mi 2 ) BGEH- 46a LPRH- 45b Habitat, Biological, Chemical Habitat, Biological, Chemical Classification 2002 Big German Cr. at Hale CR 16 28 F&W 2002 Little Prairie Cr. at Hale CR 9 24 F&W Big German Creek: At BGEH-46a, Big German Creek is a low-gradient stream located in the Blackland Prairie (65a) subecoregion (Appendix J). The bottom substrate was primarily sand overlying hardpan clay. Habitat quality was impaired by poor instream habitat, eroded banks, and a historically straightened stream channel. Six EPT families were collected, indicating the macroinvertebrate community to be in good condition (Appendix K). The fish community was assessed as fair (Appendix K). Nutrient concentrations (NO 2 +NO 3 -N, DRP) were elevated on May 8 th of 2002 (Appendix M). The dissolved oxygen concentration was 4.9 mg/L on July 12 th of 2002. 187
