The North River Watershed (Watershed Boundary Dataset 03160112) drains an area of about 1,110 km2 in Fayette and Tuscaloosa Counties and is a major tributary of the Black Warrior River. It joins the Black Warrior River at the Fall Line near Tuscaloosa, Alabama. The North River’s water quality use classification is Fish and Wildlife. A 43.48 mile segment of the North
River has been identified on the 1998 ‐ 2008 CWA Section 303(d) lists for nutrient, s
iltation, and habitat alteration impairments. The source of impairments is listed as aba
ndoned surface mining. The 2010 Section 303(d) list identifies both the North River and Lake Tuscaloosa as being impaired by atmospheric mercury deposition. A 1998 Watershed Assessment conducted by the Tuscaloosa Soil and Water Conservation District (TC‐SWCD)
Advisory Committee ranked the North River as their number one
priority impaired subwatershed (Hydrologic Unit Code 03160112‐204). A subsequent county wide assessment conducted in 2007 by the TC‐SWCD estimated that 93,600 tons of soils were eroding each year. Erosion from forest harvesting and streambank degradation was identified as primary contributors to in‐stream sedimentation.
