THE COEUR D’ALENE TRIBE WATER RIGHTS – Amends and adds to existing law to establish provisions regarding the 2026 Coeur d’Alene Tribe water rights settlement agreement and to provide for the Coeur d’Alene tribal water supply bank.

This bill approves and ratifies the Coeur d'Alene Tribe's 2026 water rights settlement agreement, which resolves a long-standing legal dispute over water rights in the Coeur d'Alene-Spokane river basin. It directly affects the Coeur d'Alene Tribe, as the agreement governs their federally reserved water rights, and potentially other water users who may lease these rights. The bill creates a "tribal water supply bank" managed by a local committee to lease the tribe's consumptive water rights (including surface and groundwater) to outside users for beneficial use, outside the tribal reservation. This mechanism allows the tribe to rent out portions of their water rights while maintaining their legal entitlements, with rules modeled after existing state water supply bank procedures.
