SubstantiveWhat changed in REPORTED TO SENATEcompared with INTRODUCED IN SENATE (Jan 29, 2026)

A complete substitute amendment. v2 fundamentally restructures the bill, consolidating sections, adding explicit compliance requirements with reclamation laws and standards, and significantly altering the funding mechanism for the feasibility study from an authorization of appropriations to a limitation on expenditures from identified existing funds. The authority's termination date is also shortened.

View bill text

Sponsor: Sen. Thune, John [R-SD]
Committees: Energy and Natural Resources Committee (primary)
Last action: Sep 17, 2026

Bottom line

The bill authorizes a federal feasibility study, with a 50% federal cost share, to explore expanding a critical regional water system in the Upper Midwest, potentially paving the way for future federal infrastructure investment.

What it actually does

This bill requires the Secretary of the Interior to conduct a feasibility study for expanding the Lewis and Clark Regional Water System in Iowa, Minnesota, and South Dakota. The study will assess the technical and financial viability of a proposed project to supply municipal, rural, and industrial water, and recommend whether it should be authorized for construction. The federal share of the study costs is capped at 50% and $10,000,000, with the authority for the study expiring in five years.

Proponents argue

Proponents argue that this bill addresses a vital need for reliable water infrastructure in the affected states, supporting public health, economic development, and agricultural stability. They contend that a thorough federal feasibility study is a necessary and responsible first step to ensure any future construction project is well-planned, cost-effective, and meets established reclamation standards, while also ensuring local stakeholders contribute to the initial assessment.

Opponents contend

Opponents, if any, might express concerns about the potential for this feasibility study to become a precursor to a much larger federal spending commitment for construction, which could strain federal budgets. They might also argue that local and state entities should bear a greater share of the study costs, or that the federal government should prioritize existing water infrastructure projects before initiating new studies.

The bill is short and clearly written, making it accessible for a quick read and easy to understand its core purpose.

Section 2(b)(1)

Feasibility Study Requirement

prominently featuredstraightforward

This provision mandates that the Secretary of the Interior, through the Commissioner of Reclamation, conduct a study to determine the feasibility of expanding the Lewis and Clark Regional Water System. The study must adhere to existing reclamation laws and feasibility standards, ensuring a consistent and rigorous evaluation process for the proposed water supply project.

Supporters argue

Supporters argue that requiring a federal study ensures a comprehensive and expert assessment of the project's viability, leveraging the Bureau of Reclamation's extensive experience in water infrastructure. This structured approach is crucial for a project of this scale and regional importance.

Critics contend

No specific opposition is typically raised against the concept of a feasibility study itself, as it is a standard preliminary step. However, some might argue that the scope or methodology of the study could be overly broad or narrow, potentially influencing its outcome.

Tradeoffs

The provision balances the need for a thorough, expert assessment with the potential for bureaucratic delays inherent in large federal studies. It aims to ensure due diligence before committing to a major construction project.

Section 2(b)(2)

Feasibility Report and Recommendations

prominently featuredstraightforward

Upon completion of the study, the Secretary must develop a report that includes recommendations on whether the project is technically and financially feasible, if it should be authorized for construction, and the appropriate non-Federal share of construction costs, which must be at least 25%. This report is then submitted to Congress and made publicly available.

Section 2(d) and (e)

Federal Share and Funding Limitation for Study

prominently featuredstraightforward

These provisions stipulate that the federal share of the feasibility study costs cannot exceed 50% of the total, and the total federal expenditure for the study is capped at $10,000,000. The Secretary is also required to identify sources of available funds for the federal share within 90 days of the bill's enactment.

FOUND

The authority for the Secretary to carry out the feasibility study expires 5 years after the date of enactment of this Act.

Section 2(f)

Why it matters:The placement is standard legislative practice for termination clauses. However, its brevity and location might obscure its significance in setting a firm deadline for a potentially complex study.

Case for: Proponents would argue that a 5-year termination clause encourages efficiency and timely completion of the study, preventing it from languishing indefinitely. It ensures that resources are focused on delivering a report within a reasonable timeframe.

Case against: Critics might contend that 5 years is an aggressive timeline for a comprehensive feasibility study of a large, multi-state regional water system, especially considering potential bureaucratic hurdles, environmental reviews, and coordination with multiple federal, state, and local entities. An insufficient timeline could lead to a rushed or incomplete study.

Estimated impact: This provision significantly shortens the window for the study compared to the original bill's 10-year timeframe, impacting the pace and potential thoroughness of the assessment.
