Potomac River Monitoring Sites

After a snowy winter, river levels in late spring returned to near-drought levels with flows below normal for this time of year. USGS stream gages feed data to a national system that allows real-time data to be displayed, with hourly updates. In addition, sophisticated forecasting systems are available for a number of monitoring stations managed by NOAA. Click on a marker or choose a site below for details.
