Thoman is a privately owned Earth dam located in Cokeville, Wyoming, on Gooseberry Creek. Built in 1945, this irrigation structure stands at a height of 25 feet and has a storage capacity of 140 acre-feet. Despite its low hazard potential, Thoman is currently assessed as being in poor condition, with its last inspection dating back to July 2018. The dam features an uncontrolled spillway, with one valve serving as its outlet gate.

Thoman's primary purpose is irrigation, serving the surrounding agricultural lands in Lincoln County. While it is state-regulated and permitted, the dam's condition assessment and risk level indicate a need for maintenance and potential risk management measures. With a moderate risk level and a history of poor condition, Thoman presents an opportunity for stakeholders to address its structural and safety concerns to ensure the continued reliability of its irrigation function and minimize potential risks to downstream areas.
