Abstract: Non-point source nutrient loading to streams and lakes poses a significant threat to water quality. In an area that is predominantly agricultural, such as the Kalamazoo River watershed in southwest Michigan, pesticide and manure run-off from farmlands exacerbates the problem. Technologies exist to quantify the threat and identify where the areas with the highest rates of nutrient contribution. However, a lack of detailed and reliable stream monitoring data has made it difficult to calibrate and compare the different technologies and subsequently discern their respective reliabilities within a Michigan environment. This project proposes running the SWAT (Soil and Water Assessment Tool) and HIT (High Impact Targeting) models on the Kalamazoo River Watershed, where thorough monitoring efforts have been underway for several years. These efforts would make significant strides in improving the reliability of non-point source models for Michigan environments.
