Desert Inn Detention Basin Dam

About Desert Inn Detention Basin Dam

The primary purpose of Desert Inn Detention Basin 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 Clark County Public Works (local government). It impounds the Las Vegas Wash-tr near Las Vegas.

The dam stands 17 feet tall and stretches 2,554 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 61 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 2002, 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 04/11/2022.
