Swan Lake, located in Kerkhoven, Minnesota, is a dam managed by the local government for flood risk reduction along the Shakopee Creek. Built in 1941 by the USDA NRCS, this dam is regulated by the Minnesota Department of Natural Resources and is subject to state permitting, inspection, and enforcement. With a height of 11 feet and a length of 800 feet, Swan Lake has a storage capacity of 3000 acre-feet and serves a drainage area of 90 square miles.

The dam's primary purpose is flood risk reduction, and it is classified as a buttress dam with an uncontrolled spillway. Despite its low hazard potential and satisfactory condition assessment, Swan Lake is subject to regular inspections every 8 years, with the last inspection conducted in September 2015. The dam has a moderate risk level, and there are no emergency action plans prepared or inundation maps available. Swan Lake provides essential water resource management for the Kandiyohi County area, ensuring the safety of local communities and ecosystems in the event of flooding.
