Where is Dueling Creek? Dueling Creek is an urban, tidal tributary of the Anacostia River. It drains a good deal of Northeast DC, the southern portion of Mt Rainier, part of Cottage City, MD, all of the Fort Lincoln Cemetery property, and nearly all of Colmar Manor, MD. It empties into the Anacostia River near the MD/DC line.
It starts underground in Mt Rainier, and has a short segment above ground in a natural creek bed near Otis and 37th St. Then the stream is contained in a cement culvert briefly before emerging again in a lovely stretch in Cottage City in a private-access/no-use piece of park land. Then back into cement to cross under Bladensburg Rd and into the Colmar Manor park. Here is the whole watershed:
Inside the park, as it crosses under the park road for the last time, it returns to a natural creek bed. At this point it is much larger, and increasingly affected by the tides. This section of the creek bed is actually the old Anacostia River bed, which explains the large forested river bottomland there – with large sycamores and maples, it is a unique habitat. One side of the creek is bordered most of the way by the Fort Lincoln Cemetery.
A popular viewing spot is found towards the back of Colmar Manor park, where there is a small dock reaching across the flood plain. To get to the rest of the creek bed, you have to bushwhack as there are no maintained trails.
