Reclamation Managing Water in the West: Minidoka Dam Spillway Replacement, Minidoka Project, Idaho. Final Environmental Impact Statement

摘要

This Final Environmental Impact Statement (Final EIS) examines alternatives to correcting structural problems at the Minidoka Dam Spillway and associated facilities on Lake Walcott, Idaho. Alternatives considered in the Draft EIS are the No Action, as required under the National Environmental Policy Act; total replacement of the spillway and headgate structures; and replacement of just the spillway. Total replacement of the spillway and headgate structures is the preferred alternative. Proposed changes in operations following construction are also discussed. In addition, certain public activities became restricted per 43 CFR Part 423 Public Conduct on Bureau of Reclamation Facilities, Lands, and Waterbodies which became effective on October 1, 2008. The Final EIS identifies special use areas to be designated under each of the action alternatives that would open areas currently closed for public use.
