  1. Beaverdam Creek:An Environmental Perspective

  2. Chesapeake Bay Watershed

  3. Anacostia Watershed Background • Urban, over 75% Developed • Size : 176 mi2; avg. daily discharge: 138 cfs • Drains both Piedmont and Coastal Plain • 8.4 mile long tidal freshwater river portion • Overall, approximately 25% impervious • 805,000 + residents • Diversity of people and streams

  4. Six Restoration Goals Goal 1: Reduce Pollutant Loads Goal 2: Enhance Aquatic diversity and Encourage a Quality Urban Fishery Goal 3: Restore Anadromous Fish Spawning Range Goal 4: Increase Acreage and Quality of Wetlands Goal 5: Expand Forest Cover and Riparian Buffers Goal 6: Increase Public Awareness, Citizen Participation and “Friends of Groups”
