Loads and yields of sediment and water-quality constituents in Kentucky streams

Hydrologic and water-quality characterization and modeling of the Chenoweth Run basin, Jefferson County, Kentucky

“…A background annual total-phosphorus yield of one third of that for Cave Creek would thus be approximately 0.5 lb P/acre/yr. Phosphorus yields reported for 13 central Kentucky streamflow-gaging stations in mostly rural basins averaged 0.63 lb P/acre/yr and ranged from 0.188 to 2.22 lb P/acre/yr (Garcia and Crain, 1998). Reported generalized mean total phosphorus yields (Thomann and Mueller, 1987) (table 24) ranged from 0.18 to 0.89 lb P/acre/yr, depending upon the nonpoint-source characteristics.…”
