South Zumbro Kr-7 is a vital flood risk reduction structure located in Olmsted County, Minnesota, specifically in the city of Rochester. Built in 1994 by the USDA NRCS, this earth dam stands at a height of 22 feet and a length of 1970 feet, with a maximum storage capacity of 763 acre-feet. The dam serves to control water flow from the Cascade Creek North Fork-TR, covering a drainage area of 3.8 square miles.

Managed by the Minnesota Department of Natural Resources, South Zumbro Kr-7 is regulated, permitted, inspected, and enforced by state agencies to ensure its functionality and safety. With a hazard potential rated as high and a risk assessment indicating very high risk, the dam is deemed satisfactory in condition based on the latest assessment in June 2017. Despite its critical role in flood risk mitigation, the dam has uncontrolled outlet gates and a spillway type classified as controlled.

As a significant structure in the St. Paul District managed by the Natural Resources Conservation Service, South Zumbro Kr-7 plays a crucial role in safeguarding the local community from potential flooding events. With its satisfactory condition and regular inspections, the dam continues to provide essential flood risk reduction services while also highlighting the importance of proper management and maintenance of water resources in the face of climate challenges.
