The Park monitors Potomac River levels to determine when portions of the towpath, hiking trails or parking areas might be affected by rising river levels. By visiting the National Oceanic and Atmospheric Administration - National Weather Service Advanced Hydrologic Prediction Service, you can see a timeline of expected river rises and crests to help plan your visit to the park.

Section A of the Billy Goat Trail often closes due to flooding. Under normal conditions, the trail is closed when the gauge at Little Falls reaches 5 feet and reopens when the gauge falls to 4.8 feet. However, under certain circumstances, the trail may be closed at lower levels. Please call the Great Falls Tavern Visitors Center at 301-767-3714 during regular business hours for the latest information on trail closures.
