Nanjemoy WMA consists of several parcels of land situated along the Potomac River and Route 224 in southwestern Charles County that were acquired beginning in 2001. The Nanjemoy WMA areas of Wilson Farm, Liverpool Point, Douglas Point, Ben Doane Rd. and Purse encompass a total of 1830 acres open to recreational activities such as bird watching, fishing and hunting.  The 185-acre Wilson Landing Area is leased to Charles County Recreation and Parks for operation as a County Park with boat launching facilities.  An additional 548 acres is managed by the Bureau of Land Management as the Douglas Point Special Recreation Management Area.

Nanjemoy WMA offers a variety of habitats and miles of marked and unmarked trails. At the end of Wilson Landing Rd. there is an inlet known as Mallows Bay - a unique historical site where you can see the remnants of old ships. Now colonized by plants, these ships serve as osprey nesting platforms and provide fish habitat. At Nanjemoy WMA you are likely to see a variety of wildlife ranging from turkey, deer and foxes in the forests to Great Blue Herons, Eagles, Turtles and Ospreys along the river and in the wetlands.
