The concrete and timber crib dam was constructed in 1884 by the United States Army Corps of Engineers, with a height of 17 feet, and a length of 385 feet at its crest. It impounds the Upper Mississippi River for flood control, navigation, and municipal drinking water. Rebuilt in 1936, the dam is owned and operated by the Mississippi Valley Division of the Corps of Engineers.
The dam creates a system of connected reservoirs with a total maximum capacity of 120,000 acre-feet, and a normal capacity of 82,000 acre-feet: Jay Gould Lake, Cut-Off Lake, and the largest, Pokegama Lake. The dam is the location of a number of Minnesota weather records.
