About Klinkner
The primary purpose of Klinkner is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Vernon County (local government). It impounds the Knapp Creek.
The dam stands 32 feet tall and stretches 580 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 234 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1956, the structure is well into its service life at over 50 years 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 04/22/2021.
At 32 feet, this dam is taller than 76% of dams nationwide.
