About Warner Lake
The primary purpose of Warner Lake 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 Conners State College (state). It impounds the Tributary To Georges Fork near Warner.
The dam stands 46 feet tall and stretches 542 feet across, creates a reservoir covering 16 acres, has a maximum storage capacity of 878 acre-feet, and collects water from a drainage area of 17 square miles. Completed in 1942, the structure is well-established, with more than 75 years of service.
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 11/19/2020.
