Located in Money Creek, Minnesota, the Felix Detention dam was completed in 1975 by the USDA NRCS with the primary purpose of flood risk reduction. This earth dam stands at a height of 34 feet and spans 210 feet in length, with a storage capacity of 18 acre-feet. The dam is designed to control the flow of the Money Creek Offstream, with a maximum discharge capacity of 348 cubic feet per second.

The Felix Detention dam is owned and operated by a private entity and is not regulated or inspected by state agencies. Despite being classified as having a low hazard potential, its condition assessment is currently not rated. The dam features an uncontrolled spillway and outlet gates, with no associated locks for navigation. With a moderate risk assessment rating, there is a need for further evaluation and potential risk management measures to ensure the safety and functionality of this vital flood control structure in Winona County.
