South Dakota Water Feasibility Studies Act

This bill directs the Secretary of the Interior to conduct feasibility studies for three proposed water supply projects in the Dakotas, Iowa, Minnesota, and Nebraska. The legislation requires the federal government to work with specific regional water entities to evaluate whether these projects should be built and to determine the appropriate financial contributions from non-federal sources, which must be at least 25 percent of total costs. To fund these initial studies, the bill authorizes up to $10 million for each project, with the federal share of study expenses capped at 50 percent. The authority to carry out these studies expires ten years after the bill is enacted, and the resulting reports will be submitted to Congress and made public.
