Coon Creek, located in Lyon County, Minnesota, is a state-regulated earth dam completed in 1977 by Ducks Unlimited. With a height of 8 feet and a length of 550 feet, this dam serves a primary purpose other than flood control. Maintained by the Minnesota Department of Natural Resources, the dam has a low hazard potential and is in satisfactory condition as of the last inspection in 2017.

The dam on Coon Creek has a storage capacity of 100 acre-feet and a drainage area of 90.7 square miles. Despite its modest size, the dam plays a crucial role in water resource management in the area. The dam's designer, Ducks Unlimited, has implemented effective regulatory and inspection processes to ensure its safety and functionality, making it a key component of the water infrastructure in the region.

Coon Creek dam not only provides essential flood protection and water storage but also serves as a habitat for various wildlife species in the area. With its strategic location and efficient management by the Minnesota DNR, Coon Creek is a valuable asset for water resource and climate enthusiasts interested in sustainable water management practices in the Midwest.
