Quail Creek South Dam, located in Washington, Utah, is a crucial structure managed by the local government for water supply purposes. Completed in 1990, this gravity dam stands at a structural height of 80 feet, with a hydraulic height of 77 feet. It plays a vital role in storing water from the Virgin River Diversion, with a storage capacity of 37,000 acre-feet.

Maintained and regulated by the Utah Division of Water Rights, Quail Creek South Dam is subject to regular inspections to ensure its structural integrity and operational efficiency. With a high hazard potential but a satisfactory condition assessment, this dam is equipped to handle maximum discharges of up to 1,000 cubic feet per second. Its location and design make it a key component in the water management system of the region, serving the needs of the community and mitigating potential risks associated with water resource management.

Despite its importance in water supply and management, Quail Creek South Dam does not have associated spillways or outlet gates. However, its role in providing crucial water storage in an area with a drainage area of 78.4 square miles cannot be understated. As climate change impacts water resources and availability, the efficient operation and maintenance of structures like Quail Creek South Dam become increasingly vital for sustainable water management in the region.
