About Thomsen Dam

The primary purpose of Thomsen 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 Haussermann Cattle Company (private). It impounds the Tr-reams Creek.

The dam stands 21 feet tall and stretches 560 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 153 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1960, the structure is well into its service life at over 50 years old.

This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected 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 10/13/2022.
