Open public comment period

The goals of the study are to:

• Obtain a detailed understanding of current water supply and irrigation, municipal and industrial uses near the four Lower Snake River dams (Ice Harbor, Lower Monumental, Little Goose, Lower Granite) in Washington and Idaho;
• Evaluate impacts to water delivery in the event Congress were to authorize breach of the dams;
• Analyze potential solutions for water supply replacement and identify implementation considerations.

All comments must be submitted or postmarked by Mar. 1, 2025.

A contractor team led by Jacobs Engineering Group Inc. is conducting the study in coordination with and at the direction of Reclamation and Ecology. This study is one of several federal studies committed to by the U.S. government as part of the December 14, 2023, Resilient Columbia Basin Agreement. Concurrent with the public comment period, the study is undergoing an independent peer review process.
