Sidney West Dam, located in Cheyenne, Nebraska, is a local government-owned structure designed by E Y GRUPE in 1958 for flood risk reduction along the TR-LODGEPOLE CREEK. The dam, primarily made of earth with buttress and stone cores, stands at a height of 26 feet and has a structural height of 31 feet. With a storage capacity of 50 acre-feet and a maximum discharge rate of 60 cubic feet per second, the dam plays a crucial role in managing water flow in the region.

Maintained by the Nebraska Department of Natural Resources, the dam is subject to state regulation, inspection, and enforcement to ensure its structural integrity and safety. With a high hazard potential, the dam has been assessed as satisfactory, with the last inspection conducted in August 2020. Despite its small surface area and drainage area, the Sidney West Dam remains a vital infrastructure for flood control in the area, highlighting the importance of water resource management in mitigating climate-related risks.

As a key component in the local flood risk reduction strategy, Sidney West Dam serves as a critical line of defense against potential flooding events. With its strategic location and design features, including a spillway and outlet gates, the dam provides essential protection for the surrounding community. Regular inspections and maintenance efforts help to ensure that the dam continues to function effectively, underscoring the importance of proactive water resource management in the face of changing climate patterns.
