PRINCE FREDERICK, Md. – May 31, 2018 – The Calvert County Department of Planning & Zoning announces the launch of a new interactive map that allows citizens to learn about the 22 watersheds in Calvert County. Six of the watersheds flow directly into the Chesapeake Bay, with the other 16 flowing into the Patuxent River.

The Calvert County Department of Technology Services designed the new Geographic Information System (GIS) watershed map in conjunction with the Calvert County Environmental Commission at the direction of the Calvert County Board of County Commissioners (BOCC). When citizens view the map, they can search watersheds by address and review a fact sheet that highlights each of the 22 watersheds’ size, associated streams and nearby water quality monitoring stations.

The Environmental Commission was established in 1975 by the BOCC and is staffed by 11 citizen volunteer members who are tasked with providing advice and recommendations to the BOCC, county staff and the Calvert County Planning Commission on matters that affect the air, land and waters of Calvert County.

The Environmental Commission has also sponsored the “Pump for the Bay” contest for many years. County residents who pump out or upgrade their septic tank qualify to win cash and other great prizes. For more information about the contest or to download an entry form, go to To learn more about the Environmental Commission, visit The monthly Environmental Commission meetings are held in Prince Frederick and are open to the public.
