About Hawkins Dam

The primary purpose of Hawkins Dam is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Keeling, John & Deborah (private). It impounds the Tr-benson Creek near Carlton.

The dam stands 16 feet tall and stretches 350 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 46 acre-feet, and collects water from a drainage area of 17 square miles. Completed in 1940, 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 10/18/2021.
