Howard C. Davis Dam, located in Washoe, Nevada, is a vital water resource infrastructure designed primarily for irrigation purposes. Completed in 1945, this earth dam stands at a height of 26 feet and spans a length of 612 feet, with a storage capacity of 3,000 acre-feet. Situated on the Mosquito Lake-TR river or stream, the dam serves multiple purposes including fire protection, stock, and small fish pond irrigation.

Despite its significance in water management, the dam is currently assessed to be in poor condition with a significant hazard potential. The dam features an uncontrolled spillway and a single valve outlet gate for water release. With a drainage area of 8.9 square miles and a maximum discharge capacity of 850 cubic feet per second, the dam poses moderate risks that require ongoing risk management measures. The inspection frequency is set at every three years, with the last assessment conducted in October 2020.

As climate change increasingly impacts water resources, the maintenance and monitoring of structures like Howard C. Davis Dam become crucial for ensuring the safety and sustainability of water supplies. The dam's location in a Congressional District of Nevada highlights its importance in providing water for irrigation and other essential needs in the region. Efforts to improve the dam's condition and implement effective risk management strategies will be essential for mitigating potential hazards and ensuring the continued reliability of this critical water infrastructure.
