Abstract

Non-point source pollutants from agricultural and forested lands have accounted for more than 50% of pollutants entering the waterways of the nation (Hornbeck, J.W. and Reinhart, K. G., 1964). Studies (Farrish, K. W., Adams, J. C., and Thompson, C. V., 1994) have shown that sediment is the major non-point source pollutant that causing the reduction of stream water quality. This paper reports the preliminary result from a project funded by Environmental Protection Agency (EPA) to develop Total Maximum Daily Load (TMDL) for the California portion of Truckee River. The Annualized Agricultural Non-Point Source Pollution Model 98 (AnnAGNPS 98), a joint USDA Natural Resources Conservation Service (NRCS) and Agricultural Research Service (ARS) system of computer models, is used as the analysis tool. The modeling result showed reasonable agreement with the available measured data, and indicated that sediment yield is closely related to watershed slope and soil characteristics.
