The bill amends Chapter 17, Title 42 of the Idaho Code by adding a new section, 42-1781, which mandates the diversion of water for the purpose of aquifer recharge in the eastern Snake Plain Aquifer. The Idaho water resource board is required to divert all available water for recharge until either the aquifer recharge goal of 350,000 acre-feet is achieved for the irrigation season or a higher goal set by an approved state water plan is met. Additionally, the diversion will cease if the director of the department of water resources provides a written declaration that the aquifer or any part of it is stable.

The bill also declares an emergency, stating that it will take effect on July 1, 2025. This legislation aims to enhance the management and sustainability of the eastern Snake Plain Aquifer by ensuring that sufficient water is diverted for recharge purposes, thereby addressing potential water resource challenges in the region.
