Ute Water Rights

Maddy summaryHJR 1017 is a joint resolution urging the federal government to fulfill its obligations under the 1986 Colorado Ute Indian Water Rights Settlement Agreement. It specifically calls for action to address infrastructure gaps affecting two tribes: the Southern Ute and Ute Mountain Ute Tribes, who have settled water rights but cannot access or use them due to missing pipelines (e.g., from Lake Nighthorse) and deteriorating irrigation systems (like the PRIIP, requiring $126 million in repairs). The resolution highlights federal failures to fund operations, maintain infrastructure, and enable tribes to utilize their legally secured water for agriculture, municipal use, and economic development. As a procedural resolution, it does not create new law but formally requests federal action to resolve these longstanding barriers.
