Cheney Dam, located in Sedgwick, Kansas, along the North Fork Ninnescah River, is a federal structure designed by the Bureau of Reclamation with a primary purpose of flood risk reduction. Completed in 1963, this earth dam stands at a height of 126 feet and has a storage capacity of 752,976 acre-feet, making it a crucial component in managing water resources in the region. With a surface area of 28,000 acres and a drainage area of 664 square miles, Cheney Dam plays a vital role in providing flood protection, recreation opportunities, and water supply for the surrounding communities.
Despite its high hazard potential and moderate risk assessment, Cheney Dam has not undergone a recent condition assessment, and the last inspection was conducted in August 2020. While the dam is not state-regulated, the Bureau of Reclamation is responsible for its design, construction, regulation, inspection, and operation. The dam's uncontrolled spillway, with a width of 22 feet, helps manage maximum discharges of up to 3000 cubic feet per second during flood events. With its strategic location and significant storage capacity, Cheney Dam continues to be a critical infrastructure for water resource management and climate resilience in the region.
