The 280,000 hectare St. Joseph River Watershed, located in northeast Indiana, northwest Ohio and south central Michigan, is a Source Water Protection Initiative watershed. Located near Ft. Wayne, IN, a number of environmental (water quality) studies and community interfaces are active in this watershed.

Science Questions

•What is the impact of assimilating local information such as land use, precipitation, and meteorology on the prediction of environmental quality? Are we able to improve our predictive capabilities, and/or quantify predictive uncertainties in a better fashion?

•How can an interface be developed for multimedia analysis involving air quality, meteorology, and water quality, as well as point, spatial, intermediate, and continuous data?

•Are we able to better assess the sources and fluxes of sediments, nitrates and pesticides?
