Development of an integrated modeling study to link watershed conditions and predict receiving water body quality incorporated the following: 1) the event-based AGNPS model to estimate watershed pollutant losses; 2) annualization of AGNPS results to produce annual mass loadings to the lake; 3) the baseflow separation package, SAM, to estimate amount of baseflow; 4) estimates of nutrients in baseflow; 5) algorithms for lake water quality from EUTROMOD to estimate lake water quality; and 6) linkage of loadings from the watershed directly to lake water quality algorithms. Results for Melvern Lake, a 28-km2 multi-purpose reservoir with 900-km2 watershed dominated by agricultural land use, in east-central Kansas are presented.
