Built in 1969 for the primary purpose of irrigation, this earth dam stands at a height of 33 feet and has a hydraulic height of 29 feet. With a storage capacity of 300 acre-feet and a surface area of 28 acres, the dam helps control water flow from unnamed streams and Little McBride Creek.
Despite being classified as having a significant hazard potential, the dam is currently in fair condition and is inspected every four years. It has a spillway width of 7 feet and a maximum discharge rate of 31 cubic feet per second. While the risk assessment for the dam is moderate, there are no emergency action plans in place as of the last inspection in June 2018. With its critical role in providing water for irrigation in the region, the King Reservoir South Dam serves as a vital resource in managing water resources and climate impacts in the area.
