WATER LAW – Amends existing law regarding the director’s ability to issue orders regarding methodologies for determining material injury under the rules for conjunctive management.

This bill (S 1061) requires Idaho's Water Resources Director to provide affected water users with notice and a hearing opportunity before issuing new or revised methodologies for calculating "material injury" under conjunctive water management rules. It applies directly to agricultural, municipal, and other water rights holders impacted by these methodology changes. The law mandates that any final order establishing such a methodology must be issued by December 1 prior to its effective year, with exceptions only for emergencies or informal dispositions. The bill takes effect July 1, 2025, ensuring procedural transparency before changes affect water rights administration.
