Cowan Lake Dam

About Cowan Lake Dam

The primary purpose of Cowan Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Cowan Farms (private). It impounds the Unknown near Honey Creek Community.

The dam stands 33 feet tall and stretches 360 feet across, creates a reservoir covering 26 acres, has a maximum storage capacity of 508 acre-feet, and collects water from a drainage area of 498 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 01/20/2016. That was 10 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 33 feet, this dam is taller than 78% of dams nationwide.
