About Northeast C-1 Detention Basin Dam

The primary purpose of Northeast C-1 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 City Of Henderson (local government). It impounds the Las Vegas Wash-tr near Henderson.

The dam stands 39 feet tall and stretches 787 feet across, creates a reservoir covering 14 acres, has a maximum storage capacity of 340 acre-feet, and collects water from a drainage area of 9 square miles. Completed in 2010, 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 02/27/2024.

At 39 feet, this dam is taller than 86% of dams nationwide.
