This earth dam stands at a height of 80 feet and has a storage capacity of 1800 acre-feet. The dam spans 775 feet across Cataract Creek, with a spillway width of 20 feet to manage maximum discharge levels of up to 1250 cubic feet per second.
Despite its essential role in providing water for irrigation, the dam's condition assessment is rated as poor, with a high hazard potential. The last inspection in June 2018 revealed the need for improvement, and the dam's emergency action plan may not meet current guidelines. With a moderate risk assessment rating, there are concerns about the dam's ability to withstand potential emergencies or extreme weather events, highlighting the importance of ongoing monitoring and maintenance efforts by the owner to ensure the safety and reliability of this vital water resource infrastructure.
