About Fenske Dam
The primary purpose of Fenske 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 St George Ranch Inc (private). It impounds the Tr-lodgepole Creek near Lodgepole.
The dam stands 17 feet tall and stretches 905 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 90 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1964, 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 04/18/2022.
