South Branch Potomac at Petersburg

USGS Streamflow Monitor

The U.S. Geological Survey operates a stream monitoring site on the South Branch Potomac River near Petersburg, West Virginia, designated as station 01606500. Located in Grant County, this site provides continuous real-time data on river stage and discharge, supporting flood forecasting and water resource management across the region. It monitors a drainage area of approximately 651 square miles and sits at an elevation of about 966 feet above sea level. With streamflow records dating back to 1928, the station offers a long-term dataset valuable for hydrologic analysis, environmental research, and understanding seasonal flow variations in the Potomac watershed.

Federal and state agencies maintain river level monitors throughout the Potomac River Basin. The U.S.Geological Survey compiles real-time information from river monitors, in cooperation with the U.S. Army Corps of Engineers.

NOAA has an online chart of flow conditions and forecasts, as shown by the chart below:
