Dam 4 Boat Ramp provides access to the Potomac River above Dam #4 in Sharpsburg, Maryland, with a single concrete ramp suitable for small vessels (under 16 feet).

The site features a large paved parking lot with 23 car spaces and 14 trailer spaces, permanent restrooms, and a soft launch option. Important note: all boaters must exit the river before Dam #4, which is a significant river hazard.
