About Gash Dam
The primary purpose of Gash Dam is fish and wildlife pond. The dam creates habitat for fish and wildlife, supporting local ecosystems and potentially serving conservation goals. The dam is owned by Evertt M Gash (private). It impounds the Tr-maries Creek near Sweet Springs.
The dam stands 26 feet tall and stretches 510 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 32 acre-feet, and collects water from a drainage area of 140 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.
