Dakota Mainstem Water Supply Project Feasibility Study Act

119th Congress Introduced Jan 29, 2026

Summary

What This Bill Does

This bill defines Dakota Mainstem Regional Water System, Inc. as the non-Federal project entity for a cooperative agreement with the Secretary of the Interior. It also defines the reclamation feasibility standards that would govern the study: the eligibility criteria and feasibility study requirements in part 404 of title 43 of the Code of Federal Regulations.

The bill then allows the Secretary, in consultation with Dakota Mainstem Regional Water System, Inc. and through a cooperative agreement, to conduct a feasibility study for constructing a project that would supply municipal, rural, and industrial water to the Dakota Mainstem service area in South Dakota, Iowa, Nebraska, and Minnesota. The study must comply with reclamation feasibility standards. The federal share of study costs may not exceed 50 percent, the bill authorizes $10,000,000 for the work, and the authority expires 10 years after enactment.

Who Benefits and How

Dakota Mainstem Regional Water System, Inc. benefits because the bill gives the named nonprofit a federal cooperative-agreement pathway for a feasibility study and potential federal funding support. Municipal, rural, and industrial water users in the Dakota Mainstem service area benefit if the study moves a regional water supply project closer to a later construction authorization. State and local water planners in South Dakota, Iowa, Nebraska, and Minnesota benefit from a federally recognized feasibility process tied to existing reclamation standards.

Who Bears the Burden and How

The Secretary of the Interior must decide whether to undertake the study, consult Dakota Mainstem Regional Water System, Inc., administer the cooperative agreement, and ensure the study complies with reclamation feasibility standards. Dakota Mainstem Regional Water System, Inc. must operate as the non-Federal project entity under the cooperative agreement and must carry the non-Federal portion of study costs because the federal share is capped at 50 percent. Federal taxpayers bear the cost of the $10,000,000 authorization and any federal study share used under the bill.

Key Provisions

  • Defines Dakota Mainstem Regional Water System, Inc. as the non-Federal project entity for the cooperative agreement.
  • Defines reclamation feasibility standards by reference to federal eligibility criteria and feasibility study requirements.
  • Authorizes the Secretary of the Interior to study the feasibility of a Dakota Mainstem water project serving South Dakota, Iowa, Nebraska, and Minnesota.
  • Limits the federal share of feasibility-study costs to 50 percent.
  • Authorizes $10,000,000 for the feasibility study and ends the authority 10 years after enactment.
