Built in 1953, this earth dam stands at 37 feet tall and spans 264 feet in length, serving primarily for irrigation purposes. With a storage capacity of 68 acre-feet and a drainage area of 1.3 square miles, French has a significant hazard potential and is currently assessed to be in poor condition.
Despite being state regulated and inspected, French poses a moderate risk due to its condition and significant hazard potential. With a spillway width of 30 feet and an uncontrolled spillway type, the dam has a maximum discharge capacity of 1767 cubic feet per second. With only one outlet gate, the dam's emergency action plan (EAP) status, inundation maps, and risk management measures are currently unknown, highlighting the need for further evaluation and maintenance to ensure the safety of the surrounding community and water resources.
