The Sassafras River rises in western Delaware and flows westerly to the Chesapeake Bay forming the natural boundary between Cecil and Kent counties in Maryland.
The Delaware portion of the Sassafras watershed is dominated by agriculture.
EPA established a Total Maximum Daily Load for nitrogen, phosphorus, and sediment for the entire Chesapeake Bay Watershed. This TMDL requires reductions of approximately 24% for nitrogen and 20% for phosphorus between 2009 and 2025 from all of the Chesapeake watersheds within Delaware. Sediment loads from Delaware's portion of the Chesapeake must remain at 2009 levels under this TMDL.
Plants and Wildlife
Delaware's Department of Natural Resources and Environmental Control (DNREC), Division of Fish and Wildlife conducts on-going inventories of natural communities as well as rare and declining species, (e.g., state and globally-rare plants, birds, insects, mussels, reptiles, and amphibians). It maintains a database, both electronic and manual, of its findings throughout the state. Learn more about the wildlife and plant communities in this watershed from the DNREC Division of Fish and Wildlife Conservation Programs.
In addition, the Division of Fish and Wildlife, working with the University of Delaware's Institute for Public Administration - Water Resources Center, maintains online databases about plants and plant communities in Delaware. Learn more about the plant communities in this watershed from the DNREC Division of Fish and Wildlife.
