extra=The Ririe Reservoir is a reservoir located near Ririe, Idaho. It allows for irrigation, flood control, and provides recreational opportunities.

In 1972 the dam was the site of the first practical application of steelfibrous shotcrete, which was used to build a tunnel adit. [ [http://www.concrete.org/members/ACI_History_Book.pdf|ACI: A Century of Progress] ]

Ecology

The area surrounding the dam is hilly shrub-steppe and features the sagebrush and bunch grass typical of the area. The reservoir itself contains rainbow trout, kokanee salmon, smallmouth bass and yellow perch.

Possibility of Failure

If the Ririe Dam failed catastrophically, either from a natural disaster or a human initiated event, it would reach the first population center, the City of Ucon, in 108 minutes; it would reach the City of Idaho Falls, the major population center of Bonneville County, in 187 minutes. The Dam is not manned 24 hours a day and therefore it is anticipated that there would be at least a fifteen (15) minute lag between event initiation and the commencement of the notification to residents.
