119-S-3736 Journalist Public Summary

Headline Summary

A South Dakota–led bill directs the Interior Department to study whether building a regional water system across parts of SD, IA, NE, and MN makes sense, with up to $10 million authorized and the federal government covering no more than half the study’s cost.

What It Does

S. 3736 orders a formal feasibility study—done by the U.S. Department of the Interior in partnership with the nonprofit Dakota Mainstem Regional Water System, Inc.—to evaluate supplying municipal, rural, and industrial water to communities in four states. The study must follow the Bureau of Reclamation’s feasibility standards (plainly: the federal rules for analyzing costs, benefits, environmental effects, and alternatives). The federal share of the study’s cost is capped at 50%, up to an authorized $10,000,000. The authority to run the study expires 10 years after the bill becomes law. This bill does not approve or fund construction; it only funds the analysis needed to decide whether construction would be worthwhile.

Who’s For It

• Sponsors: Sen. Mike Rounds (R–SD) and Sen. John Thune (R–SD).
• Backers say a feasibility study is a low‑risk way to test whether a multi‑state water supply could improve drinking‑water reliability, support industry and farms, and plan for drought before committing to construction.
• Local governments and regional water providers in the four‑state area are likely stakeholders because the study targets municipal and rural service needs. (Formal endorsements were not listed in the provided record.)

Who’s Against It

• No specific opponents were identified in the provided record.
• Common concerns with studies like this include: added federal spending; potential environmental impacts and water‑source strain if a project later proceeds; implications for existing water rights and the need for robust tribal and community consultation; and the risk of momentum toward a costly build even if benefits are uncertain.

What’s Next

After a March 17, 2026 hearing in the Senate Energy and Natural Resources Subcommittee on Water and Power, the bill could be marked up and voted on in committee. If approved, it would head to the full Senate, then the House. It would require the President’s signature to become law.
