About Odessa City Lake Dam

The primary purpose of Odessa City Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by City Of Odessa (local government). It impounds the Tr-east Fork Sni-a-bar Creek near Wellington.

The dam stands 47 feet tall and stretches 1,150 feet across, creates a reservoir covering 90 acres, has a maximum storage capacity of 1,500 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1965, 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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 10/26/2022.

At 47 feet, this dam is taller than 92% of dams nationwide.
