About Lake Ararat Dam

The primary purpose of Lake Ararat Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Claude Cole (private). It impounds the Heads Creek near House Springs.

The dam stands 34 feet tall, creates a reservoir covering 16 acres, has a maximum storage capacity of 291 acre-feet, and collects water from a drainage area of 190 square miles. Completed in 1960, 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. The most recent inspection on record was 11/29/1979. That was 46 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 34 feet, this dam is taller than 80% of dams nationwide.
