Newhouse Commends Latest Administrative Action Protecting Lower Snake River Dams
WASHINGTON, D.C. – Today, Rep. Dan Newhouse (WA-04) released the following statement after the Army Corps of Engineers and Bureau of Reclamation announced the withdrawal of the Notice of Intent to prepare a Supplemental Environmental Impact Statement (SEIS) for the Columbia River Systems Operations.
"This decision is in line with what we have known for years; we can benefit from the Lower Snake River dams while working to improve salmon populations," said Rep. Newhouse.
Newhouse continues, "The 2020 EIS reflects the scientific evidence, community input, and stakeholder engagement that should be at the center of these discussions. Unfortunately, the Biden administration disregarded these key parts of the process. I am glad to see this administration’s Army Corps of Engineers and the Bureau of Reclamation reverse course and rescind the plan for a supplemental EIS targeting our dams."
Background:
In September 2020, the “Columbia River System Operations Environmental Impact Statement Record of Decision” for the Columbia River System Operation Environmental Impact Statement (CRSO EIS) published by the co-lead agencies, found that the Lower Snake River Dams should not be breached. Instead, it found that efforts should be focused on improving and maintaining hydropower assets while working to improve salmon passage and conditions.
Subsequently, in December of 2023, the Biden Administration announced a 10-year stay in the CRSO mediation, alongside the new Resilient Columbia Basin Initiative (RCBI), an agreement that provides taxpayer dollars for wild fish restoration in the Columbia Basin. The RCBI includes U.S. government commitments that are detrimental to the operations of the CRSO and include a number of initiatives designed to weaken the operation of the Lower Snake River Dams and lead to their eventual breach. One of these commitments included a review of existing environmental compliance documents and initiating any supplemental compliance documents, which the previous administration deemed necessary when it issued a notice of intent (NOI) to supplement the 2020 EIS. This all occurred without the input of key regional stakeholders and was justified through unscientific studies.
On June 12, 2025, President Trump signed a Memorandum revoking the Biden Administration’s “Restoring Healthy and Abundant Salmon, Steelhead, and Other Native Fish Populations in the Columbia River Basin” Memorandum.
The Memorandum directs the Secretary of Energy, the Secretary of the Interior, the Secretary of Commerce, and the Assistant Secretary of the Army for Civil Works to withdraw from agreements stemming from Biden’s misguided executive action, including the December 14, 2023, Memorandum of Understanding (MOU) filed in connection with related litigation.
Rescinding the NOI for a Supplemental EIS is the latest step in reversing the Biden administration's executive actions targeting the Lower Snake River dams.
