Clear Lake, located in Waseca, Minnesota, is a concrete dam constructed in 1937 with a height of 8 feet and a hydraulic height of 4.1 feet. The dam serves a primary purpose of "Other" and has a normal storage capacity of 6,500 acre-feet within its 611-acre surface area. The drainage area for Clear Lake is 38 square miles, with a controlled spillway width of 18 feet.

Managed by the local government, Clear Lake is regulated, permitted, inspected, and enforced by the Minnesota Department of Natural Resources (MNDNR EWR). The dam has a low hazard potential and is considered to be in satisfactory condition as of the last assessment in 2012. Despite its low hazard potential, Clear Lake poses a very high risk due to its location and potential impact on the surrounding area in case of a failure.

Enthusiasts of water resources and climate will appreciate Clear Lake for its historical significance and the critical role it plays in managing water levels and protecting the local environment. With its impressive storage capacity and controlled spillway, Clear Lake stands as a testament to effective water management practices in Minnesota.
