Antelope Detention Dam, located in Mohave County, Arizona, was completed in 1965 by the Bureau of Land Management to serve as a gravity dam for debris control on Clayhole Wash.
With a hydraulic height of 28 feet and a structural height of 29 feet, the dam has a storage capacity of 765 acre-feet, with a normal storage level of 610 acre-feet. The dam spans 2008 feet in length and covers a surface area of 108 acres, protecting the surrounding area from debris flow and potential flooding.
Managed by the Bureau of Land Management, Antelope Detention Dam boasts a low hazard potential and fair condition assessment, making it a reliable structure for mitigating risks associated with debris flow. The dam operates with an uncontrolled spillway type and has a maximum discharge capacity of 2133 cubic feet per second. Despite its relatively low risk profile, the dam undergoes inspections every 5 years to ensure its continued functionality and safety for the community of Saint George, Utah, located just 48 miles away.
While Antelope Detention Dam has not been modified since its completion, it serves as a crucial infrastructure for the region, offering protection against potential debris flow events. With its moderate risk assessment and effective risk management measures in place, the dam continues to play a vital role in safeguarding the area and its residents from the impacts of extreme weather events and climate variability.
