Howie Dam

About Howie Dam

The primary purpose of Howie Dam is fire protection, stock, or small fish pond. The dam maintains a small impoundment used for fire suppression, livestock watering, or as a fish pond. The dam is owned by Raymond Howie (private). It impounds the Tr-white Owl Creek.

The dam stands 22 feet tall and stretches 520 feet across, creates a reservoir covering 23 acres, has a maximum storage capacity of 306 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1949, 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 11/18/2021.
