Dakota Mainstem Water Supply Project Feasibility Study Act

119th Congress Introduced Feb 3, 2026

Summary

What This Bill Does

The Dakota Mainstem Water Supply Project Feasibility Study Act defines Dakota Mainstem Regional Water System, Inc. as the nonfederal project entity and ties the study to Bureau of Reclamation feasibility standards in 43 C.F.R. part 404. The bill allows the Secretary of the Interior, through a cooperative agreement and in consultation with Dakota Mainstem, to study whether to construct a project supplying municipal, rural, and industrial water to the Dakota Mainstem service area across South Dakota, Iowa, Nebraska, and Minnesota. The study must comply with reclamation feasibility standards. The federal share may not exceed 50 percent of study costs. Congress authorizes $10 million for the Secretary to carry out the study, and the authority expires 10 years after enactment.

Who Benefits and How

Dakota Mainstem Regional Water System benefits because it can become the nonfederal partner for a federally supported feasibility study. Rural communities, municipal water users, and industrial water users in the service area benefit if the study advances a reliable regional water supply option. South Dakota, Iowa, Nebraska, and Minnesota water planners benefit from a formal reclamation-feasibility process. Construction and engineering firms may benefit later if the study leads to project development.

Who Bears the Burden and How

The Interior Department and Bureau of Reclamation must negotiate the cooperative agreement, oversee the study, apply feasibility standards, and manage the $10 million authorization. Dakota Mainstem must participate as the nonfederal entity and provide or secure at least half of study costs because the federal share is capped at 50 percent. Federal taxpayers fund the federal share. The authority expires after 10 years, creating a deadline for study work and decisions.

Key Provisions

  • Defines Dakota Mainstem Regional Water System, Inc. as the nonfederal project entity.
  • Authorizes an Interior-led feasibility study for municipal, rural, and industrial water supply across four States.
  • Requires compliance with reclamation feasibility standards.
  • Caps the federal share at 50 percent, authorizes $10 million, and sunsets authority after 10 years.
