Dierssen Wildlife Management Area is a Wildlife Management Area (WMA) near Seneca in Montgomery County, Maryland.[1][2]

The WMA covers a 40-acre (16 ha) tract of marshy woodland, with two man-made ponds ('impoundments') for wildlife, located between Chesapeake & Ohio Canal towpath (mileposts 20.08 to 20.90[3]) and the Potomac River. The nearest access point is the Pennyfield Lock parking lot at MP 19.7.

Unlike most WMAs in Maryland, Dierrsen is a wildlife sanctuary - no hunting is allowed, but hiking and photography are encouraged. Because of the impoundments and location on the Potomac migration route, the tract is a well-known habitat for waterfowl, wading birds and songbirds. There are nesting boxes for wood ducks. Also present are white-tailed deer, grey and red fox, beaver, and wild turkeys. The site, donated as a waterfowl sanctuary, is named for Marshall Bidwell Dierssen.[4]
