You will find a Subwatershed Profile providing basic information about catchment area, human population density, dominant land uses, impervious surface, physical and biological stream characteristics, and wetland and forest cover.

The map below shows the division of the 176-square-mile Anacostia watershed into Subwatershed Management Units (shown in green, yellow, and brown). The Anacostia Watershed Restoration Committee (AWRC) designated these areas as a part of its goal of improving the coordination of monitoring and restoration efforts across jurisdictional boundaries.
