Headline Summary

A Senate bill to study whether bringing Missouri River water to western South Dakota is doable, how much it would cost, and how the bill would be paid for—without authorizing construction yet.

02 · Section

What It Does

The bill directs the U.S. Department of the Interior to run a feasibility study, in coordination with the Western Dakota Regional Water System (a nonprofit), on a project that would deliver municipal, rural, and industrial water from the Missouri River to the Western Dakota region. In plain terms, it orders a planning study: define options, costs, and impacts; recommend whether the project should move forward; and spell out how much non‑federal funding would be required (at least 25% of construction). The federal government could pay up to half of the study’s cost, and the results must be submitted to Congress and released to the public. Authority to carry out the study would last 10 years, with up to $10 million authorized.

Who’s For It

  • Sponsors: Sen. John Thune (R–SD) and Sen. Mike Rounds (R–SD).
  • Local water provider involvement: the study must be coordinated with the Western Dakota Regional Water System, which signals alignment with regional water planning needs.
  • Supporters’ case (in plain terms): get hard numbers and public analysis before any big spending; clarify who pays what; and assess long‑term water reliability for growing communities.

Who’s Against It

  • No formal opposition is noted in the bill text or provided actions; positions may emerge as the study scope and costs are debated.
  • Potential concerns often raised with similar studies/projects include: federal spending and cost‑share levels; environmental impacts of additional Missouri River withdrawals; tribal water rights and consultation; and whether local demand justifies eventual construction.
