The dam behind Moses Lake at Moses Lake

Moses Lake at Moses Lake is held back by Moses Lake South Dam (also recorded as Moses Lake) , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 20 ft high and running 350 ft along its crest , built across CRAB CREEK in Grant County , near BEVERLY . It was completed in 1961 , and is owned by BUREAU OF RECLAMATION (a federal owner) , to a design credited to DOI WPRS.

Its recorded primary purpose is irrigation — the pool is drawn down across the growing season to serve water rights downstream, then refilled over winter . It also serves irrigation;recreation.

NID records no spillway for it. The spillway opening is 0 ft wide.

NID classes it low hazard potential: a failure would be expected to damage little beyond the owner's own property. It is a consequence rating, not a condition rating.

NID records a maximum storage of 50,000 acre-ft against a normal storage of 50,000 acre-ft.
