require that annual withdrawal of groundwater from any groundwater source may not exceed the annual recharge of water to the groundwater source.

HB 1103 requires that any annual withdrawal of groundwater from a source cannot exceed the natural annual recharge rate of that source. The bill amends groundwater appropriation rules to prohibit approving new water rights if withdrawal would exceed recharge, based on available data. It directly affects applicants seeking groundwater rights, including agricultural users, municipalities, and industries. An exception allows withdrawals exceeding recharge for older groundwater formations used by public water systems.
