This is an animation showing the changing conditions relative to the historic record of USGS streamgages from October 1, 2024 - September 30, 2025. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.

Studying Anacostia River Quality with DOEE

The USGS and D.C.’s DOEE have been working together to monitor water quality in the Anacostia, in support of the District's goal of expanding access to the water for local communities. DOEE relies on data and continuous monitoring from USGS to support important decisions about public safety and the accessibility of the area’s natural resources.
