Minidoka Dam Spillway Replacement Environmental Impact Statement

The Bureau of Reclamation has issued a Record of Decision (ROD) to select and implement the preferred alternative to replace the spillway and headworks related to the Minidoka Dam Spillway Replacement Project.

The Final Environmental Impact Statement (EIS) outlines and evaluates alternatives considered to prevent structural failure of the existing spillway and headworks at Minidoka Dam, located on the Snake River east of Rupert, Idaho.

Three alternatives were considered in the Final EIS:

• Alternative A-No Action, as required under the National Environmental Policy Act
• Alternative B-Spillway and Headworks Replacement (Preferred Alternative)
• Alternative C-Spillway Replacement.

The action alternatives differed only in the replacement of the canal headworks.

The ROD describes the Preferred Alternative which includes the designation of Special Use Areas, the reasons for selecting this alternative, and the environmental commitments. The Preferred Alternative was identified as the most efficient and environmentally-sound option for replacing the spillway.
