About Gardner Dam
The primary purpose of Gardner 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 Dona Ana County Flood Commission (local government). It impounds the Rio Grande - Tr near Rural.
The dam stands 30 feet tall and stretches 1,100 feet across, creates a reservoir covering 17 acres, has a maximum storage capacity of 131 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1950, the structure is well-established, with more than 75 years of service.
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 10/23/2013.
