About Ussary Dam

The primary purpose of Ussary 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 John Ussary (private). It impounds the Tr-pigeon Creek near Agency.

The dam stands 33 feet tall, creates a reservoir covering 8 acres, has a maximum storage capacity of 141 acre-feet, and collects water from a drainage area of 410 square miles. Completed in 1969, 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 06/02/1980. That was 45 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.
