Monitoring the Potomac River Watershed
A "watershed" is an area of land from which water drains into a particular body of water. The Potomac River receives its water from an area that covers nearly 15,000 square miles in four states and the District of Columbia. The Potomac River empties into the Chesapeake Bay 112 miles downstream from this site.
If you live or work in the area, you may be one of the nearly 5 million people who receive drinking water from the Potomac River watershed. Monitoring water quantity and quality in the entire watershed is vital, because what happens upstream affects people and the environment downstream.
This photo is the Potomac River below K Street near 31st Street when the stage was at 13.88 feet on January 21, 1996. At a stage of 12 feet, the river will submerge this streamgage and reach nearby Wisconsin Avenue.
