About F-1 Dam Detention Basin

The primary purpose of F-1 Dam Detention Basin 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 Clark County Public Works (local government). It impounds the Flamingo Wash near Las Vegas.

The dam stands 26 feet tall and stretches 1,589 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 56 acre-feet, and collects water from a drainage area of 4 square miles. Completed in 2004, the structure is relatively new.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 02/25/2022.
