Boating and other recreational activities on the upper Potomac River should be avoided through Monday because of hazardous conditions, the Maryland Natural Resources Police said Friday.
Water levels are hazardous for recreational use along the main stem of the Potomac and at Millville on the Shenandoah River because of recent rain, a natural resources police news release said.
The warning doesn't apply to professionally guided river trips or teams of experienced white water paddlers.
The conditions also exist on the Potomac's tributaries.
