Pleasant Valley No. 7, also known as S. Girtler Detention, is a privately owned Earth dam situated in Winona, Minnesota. Built in 1968 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the Pleasant Valley Creek. With a height of 29 feet and a length of 331 feet, the dam has a storage capacity of 20 acre-feet and can handle a maximum discharge of 130 cubic feet per second.

This significant structure, with a spillway width of 20 feet and uncontrolled spillway type, plays a crucial role in mitigating flood hazards in the area. The dam's hazard potential is rated as significant, with a moderate risk assessment of 3. While the condition assessment is not rated, the dam's condition remains stable, and emergency action plans are in place to address any potential risks. Despite not being regulated by the state, Pleasant Valley No. 7 stands as a vital asset in the region's water resource management and climate resilience efforts.
