Summary: BWC River Basins The main NPS concerns within the Sipsey Fork CU were pasture, animal husbandry, mining, and forestry. NPS concerns within the U. Black Warrior R. CU were limited to sedimentation, mining, and forestry. Aquaculture was concentrated in the Blackbelt region of the L. Black Warrior R. (Fig. 11). Over 40% of the sub-watersheds in the Cahaba River, Mulberry Fork, and Locust Fork CUs were at risk to impairment from urban and point sources (Table 3, Fig. 12). Table 2.

Twenty-two water quality assessment projects and programs have been conducted since 1998 by ADEM, the U.S. Environmental Protection Agency (USEPA), the Geological Survey of Alabama (GSA), U.S. Geological Survey (USGS), University of Alabama (UA and UAB), Jefferson County, and Samford University (SU). Data from these projects and programs include both monitored and evaluated assessments. Monitored assessments are based on chemical, physical, and/or biological data collected using commonly accepted and well-documented methods. Evaluated assessments are based on observed conditions, limited water quality data, water quality data older than 5 years, or estimated impacts from observed or suspected activities. 26
