Richey is a privately owned earth dam located in Cokeville, Wyoming, along Twin Creek. Built in 1917 for irrigation purposes, this structure stands at 25 feet high and stretches 843 feet in length, with a storage capacity of 194 acre-feet. Despite its age, Richey has a low hazard potential but is currently assessed as being in poor condition, last inspected in July 2018. The dam features an uncontrolled spillway with a width of 20 feet and an outlet gate consisting of a single valve.

While Richey poses a moderate risk rating of 3, it remains under state jurisdiction and regulation by the Wyoming State Engineer's Office. Although the dam has not undergone significant modifications in recent years, it is subject to regular inspections every five years. As a crucial water resource for the area, maintaining the structural integrity of Richey is essential for ensuring continued irrigation supply and protection against potential hazards. Enthusiasts interested in water resource management and climate adaptation efforts may find Richey's historical significance and current condition intriguing for further study and monitoring.
