Gadient Detention, also known as the Wayne Gadient Structure, is a privately owned earth dam located in Goodhue County, Minnesota. Designed by the USDA NRCS and completed in 1996, this dam serves the primary purpose of flood risk reduction along the Hay Creek-OS river system. Standing at a height of 30 feet and a length of 200 feet, Gadient Detention has a storage capacity of 38.4 acre-feet and a maximum discharge rate of 150 cubic feet per second.

Managed by the MNDNR EWR, this low hazard potential structure is in satisfactory condition as of the last inspection in 2015. While it does not have a spillway, the dam features uncontrolled outlet gates and is situated in a high-risk area according to the risk assessment data. Despite its minimal modifications over the years, Gadient Detention remains an essential component of the local water resource management system and plays a crucial role in mitigating flood risks in the region.

With its strategic location in Red Wing, Minnesota, Gadient Detention serves as a testament to effective collaboration between private owners and government agencies in safeguarding communities against potential flood hazards. As climate change continues to impact water resources, structures like Gadient Detention are vital in enhancing resilience and preparedness for extreme weather events. As efforts to monitor and manage water resources intensify, Gadient Detention stands as a resilient example of proactive flood risk reduction measures in action.
