Chiwapa Ws Str 29 Dam

About Chiwapa Ws Str 29 Dam

The primary purpose of Chiwapa Ws Str 29 Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Chiwapa Watershed District (local government). It impounds the Chiwapa Creek near Pontotoc.

The dam stands 26 feet tall and stretches 900 feet across, creates a reservoir covering 24 acres, has a maximum storage capacity of 770 acre-feet, and collects water from a drainage area of 2 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. 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 05/11/2023.
