ANNAPOLIS, Md. (AP) — Maryland Natural Resources Police say boating and other recreational uses of the upper Potomac River and its creeks and stream should be avoided.

The advisory issued Wednesday runs through Friday when Natural Resources Police say it will be updated if necessary. Natural Resources Police say recent rains have made river levels hazardous in the main stem of the upper Potomac from Cumberland to Little Falls. The department says hazardous stages pose a threat to non-whitewater vessels and activities such as tubing and swimming.
