Chesapeake Bay Program

To better quantify NPS loads and the effect of all loads on the Bay, the Chesapeake Bay Program, beginning with the research phase in 1978, has placed high priority on the development of drainage basin and tidal mainstem models of the Bay. The modeling effort originated with development of the Watershed Model during the research phase. The Watershed Model simulates streamflow and point and nonpoint source nutrient loads over the entire Bay drainage basin, an area of 64,000 square miles.
