Ririe Dam and Reservoir Proposed Interim Operations
Draft Environmental Assessment

rule

Ririe DamLocated in Bonneville County, Idaho, the Ririe Project was constructed to impound and control the waters of Willow Creek for flood control, irrigation and recreation. Constructed between 1970 and 1977 by the Corps of Engineers, Ririe Dam serves the principal purpose of flood control on the lower reaches of Willow and Sand Creeks. Ririe Dam is approximately 15 miles northeast of the Idaho Falls and about 4 miles southeast of the town of Ririe.

The United State Department of Interior, Bureau of Reclamation (Reclamation) and the United States Army Corps of Engineers, Walla Walla District (Corps) are working to identify issues and concerns associated with Proposed Interim Operations of Ririe Reservoir and Dam. This study would involve analyzing flood control storage and winter water release scenarios under various conditions. The period of study would be for approximately 3-5 years. Data from these tests will provide the needed information to determine how operations may be modified in the future that will continue to meet the needs of providing flood protection for the downstream area, but also increase the opportunity to store additional winter flows for later use.

Reclamation has determined that an Environmental Assessment (EA) is required under the National Environmental Policy Act (NEPA) in order to undertake this action. The EA will evaluate the impacts of the proposed action on both human and natural environments. This analysis, together with input from the public, will assist Reclamation and the Corps in making an informed decision on the winter release testing options.
