SB 3409 declares that the Secretary of the Interior, acting through the Bureau of Reclamation, will retain sole ownership, operational authority, and long‑term financial responsibility for the Lower Yellowstone Fish Bypass Channel and related activities. The bill bars any administrative action, agreement, or transfer that would force the Lower Yellowstone Irrigation District, the Lower Yellowstone Irrigation Project, or any other non‑Federal entity to assume operations, maintenance, or Endangered Species Act obligations tied to the bypass.
The measure also authorizes $1,000,000 annually beginning in fiscal year 2026 for operation, maintenance, repairs, engineering reviews, and adaptive management, requires biennial reporting to congressional committees, and gives the U.S. District Court for the District of Montana exclusive jurisdiction over disputes. For practitioners, the bill replaces ambiguity about liability with a clear federal duty — and with it, new fiscal and administrative obligations for Reclamation and Congress while insulating local irrigation stakeholders from cost‑shifting risk.
At a Glance
What It Does
The bill requires the Secretary to keep full, perpetual ownership and operational control of the 2.1‑mile Lower Yellowstone Fish Bypass Channel, prohibits transferring any fiscal or O&M responsibility to non‑Federal entities, and authorizes $1,000,000 per year for maintenance and adaptive management beginning FY2026. It also mandates biennial reports to congressional committees and centralizes judicial review in the District of Montana.
Who It Affects
Primary actors affected are the Bureau of Reclamation (as the obligated federal operator and funder), the Lower Yellowstone Irrigation District and Project (who are insulated from costs and obligations), the U.S. Fish and Wildlife Service and Corps of Engineers (coordination partners), and Congress (which must appropriate ongoing funding).
Why It Matters
The bill codifies who pays and who manages a federal mitigation project created under the Water Resources Development Act of 2007, eliminating administrative uncertainty that could lead to cost‑shifts onto local irrigation entities. That clarity changes budgeting responsibility and narrows the range of permissible partnership arrangements for managing the bypass.

What This Bill Actually Does
SB 3409 is a narrowly targeted statute that resolves ownership and funding questions about a specific engineered fish passage built near Intake, Montana. It starts by defining the bypass channel (a 2.1‑mile engineered route intended to move pallid sturgeon and other native fish around the Intake Diversion Dam) and then sets out who counts as the relevant irrigation project and district for the statute’s purposes.
Those definitions do legal work: they delimit the objects of the bill’s prohibitions and the parties entitled to relief.
The core of the bill does three things in practical terms. First, it makes the Bureau of Reclamation — via the Secretary of the Interior — the perpetual owner and operator of the bypass and the sole party responsible for repairs, upgrades, and adaptive management.
Second, it prohibits any federal agency or administrative arrangement from transferring that financial or operational responsibility to the Lower Yellowstone Irrigation District, the Lower Yellowstone Irrigation Project, or any other non‑Federal entity, and it voids prior administrative attempts to do so. Third, it establishes a funding mechanism and accountability framework: $1,000,000 authorized each year beginning FY2026, limits on delegation or transfer of those funds, and a biennial report to the relevant congressional committees describing operations, costs, repairs, and interagency coordination.The bill preserves existing water rights, contracts, and the current statutory duties under the Endangered Species Act and NEPA; it explicitly assigns ESA obligations for pallid sturgeon recovery associated with the bypass to the Secretary and the Director of the U.S. Fish and Wildlife Service, while stating that the local irrigation district and project have no ESA obligations connected to the bypass.
For enforcement the statute gives affected stakeholders — including the irrigation district and project — standing to seek declaratory or injunctive relief in federal court and names the District of Montana as the exclusive venue. Finally, it bars creation of private causes of action against the local non‑Federal entities over bypass operations, insulating them from litigation exposure tied to this infrastructure.
The Five Things You Need to Know
The bill defines the Lower Yellowstone Fish Bypass Channel as a 2.1‑mile engineered fish passage located near Intake, Montana, built to aid pallid sturgeon and other native species.
Section 4 requires the Secretary to retain full ownership, operational authority, and financial responsibility for the bypass in perpetuity and forbids delegating or transferring those responsibilities to non‑Federal entities.
Section 8 authorizes $1,000,000 for FY2026 and each fiscal year thereafter specifically for continuous operations, repairs, engineering evaluations, upgrades, and adaptive management of the bypass, and forbids transferring those funds to non‑Federal actors.
Section 6 invalidates any prior administrative action, agreement, or cost‑sharing arrangement that would shift operations or maintenance costs for the bypass onto the Lower Yellowstone Irrigation District or Project and requires termination of inconsistent agreement provisions.
Section 7 gives the Lower Yellowstone Irrigation District, the Lower Yellowstone Irrigation Project, and other affected stakeholders a right to petition federal court for relief and designates the U.S. District Court for the District of Montana as the exclusive forum for disputes under the Act.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Provides the Act's formal name, the "Lower Yellowstone River Native Fish Conservation Act." This is procedural but anchors later references to the statute in agency and congressional communications.
Findings establishing the bypass's federal origin and purpose
Catalogs legislative facts: Congress notes the bypass was authorized under WRDA 2007, constructed using Corps and Reclamation resources and MRRP appropriations, and sits outside the irrigation project's operational footprint. Those findings function as statutory context supporting the Act’s direction that the project is a federal mitigation measure and not part of the local irrigation system — language courts will likely use to interpret disputes over ownership and obligations.
Key definitions (channel, district, project, O&M, Secretary)
Sets the statute's operative vocabulary: the bill explicitly defines the bypass by length and location, explains who the Lower Yellowstone Irrigation District and Project are, and defines 'operations and maintenance' broadly to cover repairs, upgrades, and labor. Those definitions constrain later prohibitions and enforcement provisions and reduce ambiguity about what kinds of actions and costs the federal government is committing to cover.
Reaffirmation of federal ownership, control, and sole O&M responsibility
Directs the Secretary to retain sole ownership, operational authority, and financial responsibility for the bypass forever. It bars any administrative action, agreement, or transfer that would diminish those duties and explicitly permits coordination with other federal agencies while preserving the federal hold on ownership. Practically, agencies may still cooperate operationally, but contractual or intergovernmental arrangements cannot legally shift control or cost to a non‑Federal party under this statute.
Preserves federal ESA obligations and shields local entities from ESA duties
Allocates responsibility for pallid sturgeon recovery actions connected to the bypass to the Secretary and the U.S. Fish and Wildlife Service and states the local irrigation district and project shall not be required to fund, perform, or participate in ESA‑mandated activities tied to the bypass. That separation reduces litigation and compliance risk for local water managers but concentrates recovery obligations within federal agencies.
Prohibits transfer or delegation and voids prior cost‑shift attempts
Bans any transfer, delegation, or assignment of financial, operational, or maintenance responsibilities to any non‑Federal entity, including state and local governments and private parties, and declares prior administrative cost‑sharing arrangements that attempt such transfers null and void. The Secretary is directed to terminate agreement provisions inconsistent with the Act. This provision has immediate practical effect for existing MOUs and contracts that contemplated shared responsibility.
Enforcement mechanisms and exclusive Montana jurisdiction
Creates a private right to petition the federal district court (for the irrigation district, the irrigation project, and any affected stakeholder) when the Secretary attempts an impermissible transfer, and designates the U.S. District Court for the District of Montana as the exclusive forum. Simultaneously, the Act says it does not create a private cause of action against the local non‑Federal entities for bypass operations — a deliberate asymmetry that lets federal entities be challenged without exposing local actors to new suits tied to bypass maintenance.
Funding, restrictions on fund transfer, and reporting
Authorizes $1,000,000 per year starting FY2026 for uninterrupted operation, engineering evaluations, repairs, upgrades, and adaptive management, instructs the Secretary to administer those funds, and forbids transferring them to non‑Federal entities. It also requires a biennial report to the relevant Senate and House committees outlining operational status, planned repairs or adaptive measures, an updated cost analysis, and coordination efforts. That reporting requirement is the bill’s accountability mechanism; appropriation remains subject to annual congressional action.
Effect clause preserving existing rights and federal duties
Affirms the Act does not alter the irrigation project's authorized purposes, existing water contracts or rights, state water law, or federal obligations under ESA or NEPA. In practice this limits the bill’s reach: courts will be asked to reconcile the new statutory command about ownership and funding with preexisting compacts, contracts, and environmental legal duties when conflicts arise.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Lower Yellowstone Irrigation District — the bill expressly shields the district from financial or operational responsibility, reducing risk of assessments, bond obligations, or forced staffing to support bypass operations.
- Bureau of Reclamation (Secretary of the Interior) — gains statutory clarity and exclusive authority to manage, fund, and make adaptive decisions for the bypass, which simplifies internal chain‑of‑command and budget planning.
- Pallid sturgeon recovery and conservation groups — the statute commits the federal government to maintain and adapt the engineered passage, which preserves a long‑term federal mitigation commitment tied to species recovery.
- Farmers and irrigation water users served by the Lower Yellowstone Project — they avoid potential cost allocation or operational disruptions that could have accompanied a forced local takeover of bypass obligations.
- Congressional oversight committees — the biennial reporting requirement creates a structured information flow (costs, repairs, coordination) to the Senate Energy and Natural Resources Committee and the House Natural Resources Committee.
Who Bears the Cost
- Federal government / Bureau of Reclamation — assumes ongoing O&M, repair, monitoring, and adaptive management costs for the bypass; those are placed on the Interior Department’s budget and, by extension, on federal appropriations.
- U.S. taxpayers and appropriations process — the $1,000,000 annual authorization (and any amounts Congress chooses to supplement) must be funded through appropriations, creating recurring fiscal exposure.
- U.S. Fish and Wildlife Service and other federal partners — carry extra programmatic and coordination duties for species recovery tied to the bypass, including science, monitoring, and potential regulatory actions.
- Congressional appropriations staff and oversight offices — bear administrative load to evaluate biennial reports and consider funding adequacy year to year, particularly if costs exceed the authorized floor.
- Federal procurement and engineering contractors — O&M and adaptive management work will likely be procured and funded at federal expense, concentrating execution risk and contract management on federal procurement channels.
Key Issues
The Core Tension
The bill resolves who must shoulder conservation duties and costs by concentrating ownership and financial responsibility in the federal government, protecting local irrigators from burdens but constraining collaborative, potentially cost‑sharing approaches; the central dilemma is whether preserving local fiscal shelter and legal clarity is worth restricting partnership flexibility and placing potentially open‑ended financial obligations on federal budgets and operations.
The statute resolves a common administrative ambiguity — who pays for a federally built mitigation structure — by fixing responsibility with the Bureau of Reclamation and forbidding transfers. That clarity is valuable, but it trades away flexibility.
By voiding prior agreements and banning delegations, the bill can limit cooperative cost‑sharing models that sometimes lower long‑term federal expense and leverage local operational knowledge. Those tradeoffs could affect the efficiency and responsiveness of repairs or adaptive measures in a dynamic river system.
Second, the funding element is an authorization of $1,000,000 per year, not a guaranteed appropriation, and that figure may understate the real O&M and adaptive management cost profile for a 2.1‑mile engineered channel tied to a river with changing hydrology, sediment load, and climate effects. If Congress does not appropriate sufficient funds, the statutory responsibility remains with Reclamation but without assured resources, creating operational strain and potential deterioration of conservation outcomes.
Finally, the Act centralizes litigation in the District of Montana and gives affected stakeholders the right to seek federal relief; while that fosters a single forum, it may encourage strategic litigation over the scope of the bill's prohibitions and the validity of prior agreements, particularly where the Corps, Reclamation, and state agencies have overlapping project histories.
