Confederated Salish and Kootenai Tribes


The CSKT-Montana Compact is the result of more than a decade of negotiations to resolve the Tribes' claims to reserved water rights within the State. The 2015 Legislature ratified the Compact and the parties are working on compact implementation.

The Compact will make new water available for commercial and irrigation use, end the water administration void on the Flathead Reservation, allow for economic development under conditions of legal certainty on and off the Reservation, and facilitate the completion of the statewide general stream adjudication. In addition, the Compact establishes a technical team with irrigator representation to implement irrigation project upgrades to protect historic irrigation use and meet Tribal in-stream flow targets.

Implementation Underway
One of the first steps in the implementation process is that the parties to the compact establish a Compact Implementation Technical Team (CITT). The CITT is tasked with advising the operator of the Flathead Indian Irrigation Project on the implementation of operational improvements, rehabilitation and betterment of Project facilities and on adaptive management as called for in the Compact. A Compact Management Committee (CMC) will provide policy and administrative oversight over the technical team. As of August 12, 2015, all parties have made their appointments.  DNRC Director John Tubbs will serve as the state of Montana’s CMC team member while Ethan Mace, a DNRC surface water hydrologist, will serve as the State’s representative on the CITT. The first CITT meeting is being planned for this fall.

 In addition to the CITT members appointed by the parties to the Compact, the CSKT Compact also provides for a fourth seat for the Flathead Indian Irrigation Project Operator, and also the option of a fifth seat that may be filled by a representative selected by all irrigators served by the Project should they decide to appoint one.
