The O'Sullivan Dam (National ID # WA00268) is one of the largest earth dams in the United States at 61 meters high and 5,791 meters long ; he dams the Crab Creek in Grant County in the US state of Washington , about 45 km south of Ephrata and 25 km south of Moses Lake .

The 113 km² large Potholes Reservoir , which is dammed up by the dam, collects the backflow of all irrigation systems in the upper (northern) part of the Columbia Basin Project for further use in the southern part. A trench system was built on both the West and East Low Canal to provide a degree of operational safety for the canals and a means of transporting natural water and the return flow into the Potholes Reservoir.
