Warren Twp Road, also known as Radatz Group Detention, is a critical infrastructure project located in Rushford, Minnesota, along Rush Creek-TR. This earth-type dam, completed in 1975 by the USDA NRCS, stands at 21 feet in height and spans 470 feet in length. Its primary purpose is flood risk reduction, with a storage capacity of 60 acre-feet and a drainage area of 0.38 square miles. Despite its significant hazard potential, the dam has been assessed as satisfactory and meets regulatory standards set by the MNDNR EWR.

The Warren Twp Road dam plays a crucial role in mitigating flood risks in the area, with a moderate risk assessment rating. Its uncontrolled spillway and outlet gates are designed to handle a maximum discharge of 224 cubic feet per second, safeguarding the surrounding community from potential inundation. Although last inspected in May 2019, the dam's condition remains satisfactory, reflecting the ongoing efforts of the Natural Resources Conservation Service to ensure its structural integrity and operational effectiveness.

For water resource and climate enthusiasts, the Warren Twp Road dam represents a vital piece of infrastructure in Winona County, Minnesota, serving as a key component of the local flood control system. With its buttress core type and earth construction, this dam stands as a testament to the collaborative efforts between local government agencies and federal entities like the USDA NRCS. As climate change continues to impact precipitation patterns and water levels, the importance of maintaining and enhancing such flood risk reduction structures only grows in significance.
