The Maryland Natural Resources Police has issued a safety advisory to avoid boating and other recreational activity on the Upper Potomac River until further notice.

High water, debris and weakened shoreline have combined to make the river and its tributaries, from Harpers Ferry to Little Falls, hazardous for recreational use.

This advisory does not apply to professionally-guided river trips.

Floodwaters pose a threat to non-whitewater boats, anglers, swimmers and other recreational users. Wave action, water velocity and treacherous currents can make familiar waters deadly. Boaters are reminded that all water travel involves risk and wearing a life jacket can make the difference between life and death.

For the latest information on Potomac River conditions between Cumberland and Little Falls, please call the National Weather Service at 703-996-2200. For more information on boating safety, please visit dnr.maryland.gov/boating/safety.
