Montgomery County, MD
Dierssen is a state-managed wildlife management area in Montgomery County, Maryland. The Dierssen family gave the tract to the state to serve as a waterfowl refuge. It sits between the Chesapeake and Ohio Canal Towpath and the Potomac River, and two man-made ponds draw waterfowl, wading birds, songbirds, and furbearers. Hunting and trapping are banned here, and the property has no marked trails. Visitors who are not hunting can come for birdwatching, fishing, nature photography, hiking, or biking on established trails, and the area is reached by boat or along the towpath. Rules bar fires, camping, bait, litter, and collecting plants or animals, and dogs must be leashed from April 15 through August 15.
