About Gadway Dam
The primary purpose of Gadway 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 John Lovell (private). It impounds the Tr-lodgepole Creek near Potter.
The dam stands 24 feet tall and stretches 597 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 155 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. The most recent inspection on record was 04/27/2022.
