Defending our Dams Act
Subcommittee Hearings Held
The bill bars use of federal funds to allow, lead to, or study breaching or functionally altering the four Lower Snake River dams, including studies of power, flood control, or navigation replacements and dam-removal technical assistance. It also forbids spillage operations at those dams unless approved jointly by the Secretary of the Army and the Bonneville Power Administration Administrator, who must consider Columbia River System operations.
Progressives emphasize lost opportunities for salmon recovery studies
Relative to its intended legislative type, this bill establishes clear, narrow substantive prohibitions and assigns responsible agencies, but it includes limited procedural detail, no fiscal analysis or appropriations language, scant treatment of exceptions or emergencies, and minimal oversight or accountability provisions.

The dams are defined as Ice Harbor, Lower Monumental, Little Goose, and Lower Granite in Washington.
Content is narrow and administratively clear, aiding House prospects, but Senate obstacles and stakeholder controversy reduce overall likelihood.

Who stands to gain, and who may push back.
These are examples from the analysis, not a ranked list of the most-affected groups.
- Federal agenciesLimits federal study of removal options that proponents say are needed for salmon population recovery.
- Potential burdenMay hinder spill operations used to improve juvenile fish survival without timely joint approvals.
- Federal agenciesCould constrain federal compliance flexibility with endangered species and tribal treaty obligations.
Why the argument around this bill splits.
Progressives emphasize lost opportunities for salmon recovery studies
Likely opposes the bill because it forecloses scientific study and options for restoring salmon runs and river ecosystems.
Sees the funding ban and spillage restrictions as limiting environmental management and tribal remedy options.
Cautious and mixed: supports protecting critical infrastructure until evidence justifies change, but worries a blanket prohibition on studies and assistance is imprudent.
Would favor procedural safeguards and independent analyses.
Likely supports the bill as a protection of hydropower, navigation, and local economies, and as a check on efforts to remove or alter dams.
Views spillage limits as restraining operations that harm power reliability.
