The Works Progress Administration built a dam in 1938 to create a lake, which provided an opportunity for water recreation in an area of the state with few natural lakes.

The dam was constructed of Sioux Quartzite, a hard red rock widely found in the area.

It is listed on the National Register of Historic Places as part of the Minnesota Masonry-Arch Highway Bridges MPS.
