The Northwest Branch watershed is the largest sub-watershed of the Anacostia River. It stretches over 19 miles from Sandy Spring, MD to Hyattsville, MD and parts of Northeast DC, covers approximately 41 square miles, and includes over 180,000 residents.

We, the Neighbors of the Northwest Branch, are committed to protecting, promoting and restoring the water quality, natural habitat, and ecological well-being of the Northwest Branch watershed. We intend to:
  1. foster environmental awareness and education,
  2. take action by engaging in various water quality, habitat restoration, land preservation and trash reduction efforts, and
  3. enlist broad-based public participation in and support of the foregoing goals and activities.
