The Ririe Reservoir is a reservoir located near Ririe, Idaho. It allows for irrigation, flood control, and provides recreational opportunities.
In 1972 the Ririe Dam, built on Willow Creek by the United States Army Corps of Engineers, was the site of the first practical application of steel fibrous shotcrete, which was used to build a tunnel adit.[3] The dam's total capacity is more than 100,000 acre-feet of water. On October 14, 1976, the Corps of Engineers formally transferred control of the dam to the United States Bureau of Reclamation.[4]
