About Us

Anacostia Watershed Society has a mission to protect and restore the Anacostia River and its watershed communities by cleaning the water, recovering the shores, and honoring the heritage. We believe that by working together with businesses, governments, faith-based organizations, and youth we can create sustainable solutions that improve our communities, empower our residents, and create economic prosperity that will result in a clean river. We want to change the way people think about the Anacostia and make the river a destination through our new campaign to “Rediscover Your Anacostia”!


  • Data set: All available, professionally collected data was used. The data sets include those collected by DC government, Maryland Department of Natural Resources, and the Anacostia Watershed Society.
  • The data was compared with thresholds developed by Mid-Atlantic Tributary Assessment Coalition (MTAC).
  • For the 2011 State of the Anacostia River Report, 2010 data set was used because it was the most recent available data.
  • For trend analysis, data sets from 1984 to 2010 were used depending on the parameter and the section of the river.
