Water Levels in Lower Sections of the Canal

Due to construction projects, maintenance activities, and weather, water levels in the lower portions of the canal are likely to vary throughout the year. This can affect a variety of activities throughout these areas.

The park currently actively manages water levels within two main sections of the lower portions of the canal: between Lock 4 (MP 0.54) and Lock 5/Inlet Lock 1 (MP 5.02) and between Lock 20 (MP 14.3) and Lock 23/Inlet Lock 2 (22.12). The water levels are primarily managed through the opening and closing of paddle gates on inlet lock gates, which control water entering the canal from the Potomac River, and waste weirs, which help establish the water level in the canal by draining excess water back into the river.

Open* is when the inlet lock paddle gates are open, allowing water to flow into the canal. When open, it can be assumed the water level can support boating in the canal. Closed* is when the inlet lock paddle gates are closed, blocking off water flow from entering into the canal. When closed, it can be assumed the water level will not support boating in the canal. *Water levels can change unexpectedly.

Current Status Locks 4-5: Closed
Current Status Locks 20-23: Locks 22-23 - Open. All others - Closed

River Conditions

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.
