About Hall Dam
The primary purpose of Hall 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 Steve Wiggins (private). It impounds the Tr-indian Creek near Bridgeport.
The dam stands 35 feet tall and stretches 403 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 151 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1970, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. The most recent inspection on record was 07/18/2022.
At 35 feet, this dam is taller than 82% of dams nationwide.
