Upper Little Tennessee River aerial inventory of land uses and nonpoint pollution sources
Local residents have expressed concern about water quality in the Little Tennessee River, and the possibility of nonpoint source pollution was identified. In response, TVA conducted an analysis of land uses and nonpoint pollution sources in the upper Little Tennessee River watershed. Aerial photography, taken in March 1988 and March 1989, was analyzed for the 197,000 acre watershed upstream of Porters Bend Dam (Lake Emory). In the analysis, the land surface was divided into four urban land use classes, nine agricultural land use classes, four forest land use classes, and a class for disturbed areas; livestock operations and critical sites, such as eroding roads and stream banks were located. Soil erosion rate estimates were calculated for all land uses except closed-canopy forest.
