Daines, Tester Introduce Bipartisan Legislation to Permanently Settle CSKT Water Dispute, Protect Water Rights of All Montanans

U.S. SENATE – U.S. Senators Steve Daines and Jon Tester today introduced the bipartisan Montana Water Rights Protection Act (MWRPA), a new agreement to permanently settle the century-old CSKT water dispute, and protect the water rights of all Montanans.

“After years of hard work and negotiations with the Tribe and other stakeholders across Montana, I’m pleased to introduce this bipartisan legislation today that will permanently protect the water rights of all Montanans,” Daines said. “This bipartisan bill and settlement is a good-faith compromise that will bring final resolution to a century long water dispute, avoid years of costly litigation, and save taxpayers over $400 million. I look forward to continuing to work with my colleagues in Congress, as well as the Trump administration, to get this important settlement for all of Montana across the finish line and signed into law.”

“This bill will help bring years of uncertainty for the Confederated Salish & Kootenai Tribes, taxpayers, farmers, and ranchers to an end,” Tester said. “I’m glad the CSKT Water Compact now has the backing of folks on both sides of the aisle as well as the Trump Administration—so we can move full-steam ahead to honor our trust and treaty responsibilities, prevent costly litigation, boost economic development in the region, and give long-overdue piece of mind to everyone in Northwest Montana who uses our state’s most valuable resource.”

This bipartisan legislation will not have to be voted on by the State of Montana.
