Lake Herington

About Lake Herington

The primary purpose of Lake Herington is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Herington, City Of (local government). It impounds the Kohls Creek near Lyona.

The dam stands 40 feet tall and stretches 4,000 feet across, creates a reservoir covering 100 acres, has a maximum storage capacity of 3,677 acre-feet, and collects water from a drainage area of 17 square miles. Completed in 1923, the structure is over a century old.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 03/01/2022.

At 40 feet, this dam is taller than 87% of dams nationwide.
