Glendale is an area once inhabited by Potawatomie Indians, it has been said there are burial grounds along the Milwaukee River as it winds through the park. Kletzsch Park had become one of the most popular parks in the county park system during the early 1930’s – with a river swimming beach and picnic area.
Kletzsch Park was also greatly improved with the use of relief labor. A Civilian Conservation Corps camp was established in Kletzsch Park in May of 1935 and discontinued in November of 1935.

The CCC projects completed included a new dam built across the Milwaukee River with CCC labor. The new structure, built of reinforced concrete in a serpentine design to lengthen the crest, provided increased discharge capacity without widening the river. Models prepared by the landscape design section of the planning department served as guides in erecting the stone facing and the fish ladder built into the face of the dam. The dam has the appearance of a natural waterfall.
