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.

USGS is committed to monitoring water quality and quantity in all conditions, and sometimes that means walking out onto frozen rivers to make a measurement. In this episode, we join a team as they cut through the ice to safely access the water that still flows underneath.
