Kemmerer Dam & Reservoir Rehabilitation
Kemmerer Reservoir is a 1,000-acre-foot municipal supply reservoir for the town of Kemmerer, Wyoming. Built around 1911, the structure was called unsafe in a U.S. Army Corps of Engineers dam safety inspection. The principal problems cited by the U.S. Army Corps of Engineers were: The spillway was undersized to carry the probable maximum flood, and the embankment had too-steep slopes.
The primary role of Mr. O’Grady for this project was obtaining of all permits required to construct, including the 404 Dredge and Fill Permit. Obtaining the 404 Permit was a 10-month process. Because of the dam's age, a historical evaluation was required to ascertain whether the structure was of historic consequence. Also, Kemmerer Reservoir is utilized by the Wyoming Game and Fish Department for raising brood stock. Draining the reservoir during reconstruction would kill the brood population fishery. Mr. O’Grady provided all coordination among state and federal agencies, with the outcome being the acquisition of the 404 permit.
