Only 30% of the streams that flowed through Washington, DC at the beginning of the 19th century are still found in DC today — the rest were diverted, filled in, or dried up as the city developed. These streams feed into the Anacostia and Potomac Rivers and impact water quality, biodiversity, and climate resilience for DC and the Chesapeake Bay region. The DC Department of Energy and Environment recently created an interactive StoryMap highlighting the history of buried streams in DC and the benefits of restoring them.
