Chesapeake Bay Interpretive Buoy

River Monitoring Site

blank dot

A buoy was first deployed at the mouth of the Potomac River off Point Lookout on June 4, 2007. While this buoy is located far enough south that it has remained in the water over winters, intermittent data gaps do exist due to equipment failures. Data is collected by NOAA and made available for education and navigation. Current conditions are shown below.
