The Anacostia River is an 8.5 mile long river within the Anacostia Watershed, and one of the two rivers that cross the District of Columbia .
The Anacostia Watershed is 176 square miles and includes parts of the District, Montgomery County, and Prince George's County. Nearly one million live in this watershed, either directly on the Anacostia River or on one of the many streams that connect to it. Each stream has its own watershed, and therefore is a sub-watershed of the whole Anacostia Watershed. Whatever happens in each stream and community connected by that stream affects the Anacostia River.
