About Horsehead Lake Dam

The primary purpose of Horsehead Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Arkansas Game And Fish Commission (state). It impounds the Horsehead Creek near Hunt.

The dam stands 67 feet tall and stretches 350 feet across, creates a reservoir covering 111 acres, has a maximum storage capacity of 4,913 acre-feet, and collects water from a drainage area of 16 square miles. Completed in 1950, the structure is well-established, with more than 75 years of service.

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 08/14/2025.

At 67 feet, this dam is taller than 96% of all dams in the United States.
