Dakota Mainstem Water Supply Project Feasibility Study Act

HR 7331 authorizes a federal feasibility study to assess building a water supply project serving municipal, rural, and industrial users across South Dakota, Iowa, Nebraska, and Minnesota. The study, to be conducted by the Secretary of the Interior with the Dakota Mainstem Regional Water System, must follow federal reclamation standards and determine if the project is viable. Federal funding for the study is capped at 50% of costs, with $10 million authorized, and the study must be completed within 10 years of the bill's enactment. This bill directly affects the four states' water planning but does not fund or construct the project itself.
