Located in Las Vegas, Nevada, the Red Rock Detention Dam stands as a crucial flood risk reduction structure along the Red Rock Wash. Constructed in 1987 by the USA Corps of Engineers, this earth dam measures 63 feet in height and stretches 4090 feet in length. With a maximum discharge capacity of 110,198 cubic feet per second and a spillway width of 923 feet, the dam serves as a critical defense against potential flooding in the region.

The Red Rock Detention Dam is regulated and inspected by the Nevada Department of Water Resources, ensuring that it meets safety standards and remains in fair condition. Despite its high hazard potential, the dam's risk assessment is considered moderate, with emergency action plans in place. With a storage capacity of 1,860 acre-feet and a surface area of 76 acres, this structure plays a vital role in protecting the surrounding area from the impacts of extreme weather events and climate variability.

As a significant component of flood management in the region, the Red Rock Detention Dam serves as a testament to the collaborative efforts between local governments and state agencies to mitigate flood risks and safeguard water resources. Its strategic location and design highlight the importance of infrastructure in adapting to the changing climate and ensuring the resilience of communities in the face of natural disasters.
