This bill prohibits the use of federal funds to allow, lead to, or study the breach or functional alteration of the Lower Snake River dams, including removal. It targets four specific facilities: Ice Harbor, Lower Monumental, Little Goose, and Lower Granite dams in Washington.
At a Glance
What It Does
No federal funds may be used to breach, alter, replace, or provide dam-removal technical assistance for the Lower Snake River dams. Spill operations are blocked unless approved by the Secretary of the Army and the Administrator of the Bonneville Power Administration, with consideration of all Columbia River System operations.
Who It Affects
Federal agencies charged with dam operations and funding decisions (Secretary of the Army, Army Corps of Engineers, BPA), as well as electric utilities and ratepayers relying on Lower Snake River hydropower and on-area navigation and flood-control functions.
Why It Matters
Preserving existing hydroelectric generation, flood control, and navigation capabilities in the Pacific Northwest requires coordinated, joint-agency oversight of spill practices and a formal prohibition on funding for breach or removal studies.

What This Bill Actually Does
The Defending Our Dams Act takes a targeted stance on the Lower Snake River dams. Section 2(a) blocks the use of federal funds to allow, lead to, or study any breach, alteration, or removal of the four dams—Ice Harbor, Lower Monumental, Little Goose, and Lower Granite.
It makes clear that any plans to breach or replace the dams or to provide technical assistance for removal cannot be funded with federal dollars. The goal is to lock in the existing dam infrastructure and its primary functions, including power generation, flood management, and navigation.
The Five Things You Need to Know
The bill prohibits federal funding for breach, alteration, or removal of the four Lower Snake River dams.
Funding bans extend to studies or technical assistance that would enable dam removal or major alteration.
Spill operations at these dams may not occur unless approved by both the Secretary of the Army and the BPA Administrator.
Approval of spill operations requires consideration of all Columbia River System operations.
Lower Snake River dams are defined in the bill as Ice Harbor, Lower Monumental, Little Goose, and Lower Granite.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
This section provides the act’s official name, the Defending Our Dams Act, clarifying that it is a focused mandate governing federal funding and spill decisions related to the Lower Snake River dams.
Prohibition on use of federal funds for breach, alteration, or removal
Section 2(a) bars the use of federal funds to allow, lead to, or study the breach or functional alteration of the four Lower Snake River dams, including any work that would support dam removal or replacement. The provision aims to ensure that federal dollars are not used to pursue breach or removal actions and that related technical assistance cannot be funded.
Spill operations restrictions
Section 2(b) restricts spillage operations at the Lower Snake River dams. Spillage may only proceed if approved by both the Secretary of the Army (through the Chief of Engineers) and the Administrator of the BPA. In making approval decisions, the agencies must consider all operations of the broader Columbia River System to ensure coordinated water management and energy planning.
Definitions
Section 2(c) defines the term 'Lower Snake River dams' to include Ice Harbor Dam, Lower Monumental Dam, Little Goose Dam, and Lower Granite Dam, as authorized by federal law. This ensures precise scope for the prohibitions and protections enacted in this bill.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Bonneville Power Administration and its electricity customers, who rely on stable hydropower generated by the four dams and benefit from certainty around dam operations.
- U.S. Army Corps of Engineers and the Department of Defense’s oversight bodies, which gain clear statutory guidance on funding and oversight of dam-related actions.
- Pacific Northwest utilities and large regional industrial users that depend on affordable, reliable power from hydroelectric generation.
- Washington state and local governments and communities that rely on dam-based flood control and navigation functions as part of regional infrastructure.
- Dams’ operating workforce and related contractors who maintain routine operations and safety without the risk of disruptive breach-related projects.
Who Bears the Cost
- Advocates and groups seeking to breach or remove the Lower Snake River dams lose access to federal funding for those efforts.
- Researchers, consultants, and firms that would have pursued breach or removal studies would face a narrowing set of funded opportunities.
- Agency overhead and administrative costs rise for the Army Corps of Engineers and BPA to implement funding restrictions and to coordinate spill-approval decisions.
- Taxpayers and ratepayers may incur ongoing compliance and governance costs associated with enforcing the funding prohibitions and spill-approval processes.
- Any interest groups pushing alternative river-management approaches that rely on dam removal or breaches face an opportunity-cost constraint due to the funding ban.
Key Issues
The Core Tension
The central dilemma is whether to preserve existing dam infrastructure and its energy and navigation benefits by restricting federal funding for breach or removal actions, or to empower policy pathways that could enable ecological improvements through structural changes. Each path has legitimate priorities—reliable power and flood control versus environmental and salmon habitat considerations.
The bill adds a formal prohibition on using federal funds to breach or remove the Lower Snake River dams and requires cross-agency approval for spill operations, embedding a status-quo preference for hydropower and navigation infrastructure in federal law. This creates a clear line against breaching or extensive alteration of the four dams, while still allowing for routine, approved spill management within a broader system-wide consideration of Columbia River operations.
The tension lies in balancing ecological restoration goals that some stakeholders seek with the reliability, flood protection, and navigation benefits provided by the current hydroelectric system. Implementation depends on interagency coordination and the availability of accurate, comprehensive data on the Columbia River System’s operational impacts.
