Broad Application Category:hydrologic and pollutant 
Primary Application Category:model and/or data interface 
Secondary Application Category:pollutant cycling/loss and transport 
Watershed Description:1,270 km^2 Lake Fork Reservoir drainage area, which drains parts of Hopkins, Hunt, Rains, and Wood counties in northeast Texas, U.S. 
Calibration Summary:Tabular comparisons between simulated and measured mean flows and pollutant losses are reported. 
Validation Summary: 
General Comments:SWAT was interfaced with the APEX and FEM models to evaluate the impacts of several pasture-based dairy scenarios in the watershed. The scenarios pasture stocking density adjustments and changes in in fertilizer rates applied to the pastures, to depict different N and P rate scenarios. Significant reductions in nutrient losses were predicted for the scenarios; the greatest was 54 & 13% for soluble & organic losses when P was assumed to be totally plant available. 
Keywords:stocking density, manure, nutrient losses, nitrogen, phosphorus, economics
