Williams is a privately owned dam located in Crook, Wyoming, along the Redwater Creek, with the primary purpose of irrigation. Built in 1957, this earth dam stands at 30 feet high and has a hydraulic height of 25 feet. With a storage capacity of 219 acre-feet, Williams serves as a vital resource for agricultural water supply in the region.

Despite its low hazard potential, Williams is currently in poor condition, as indicated by a 2018 inspection. The dam features an uncontrolled spillway with a width of 150 feet and a single slide gate as its outlet. While the risk assessment deems it as moderate, there are no documented risk management measures in place, raising concerns for the structure's long-term safety and stability.

With its historical significance and continued role in supporting local irrigation needs, Williams serves as a crucial water resource infrastructure in the area. However, its deteriorating condition highlights the importance of regular inspections and potential maintenance or rehabilitation efforts to ensure the safety and reliability of this essential water management asset for the community.
