water resources; technical correction.

HB 2143 is a technical correction to Arizona Revised Statutes § 45-103, updating the language to replace references to the "Arizona water commission" and "state water engineer" with "the director" of the water department. This bill streamlines administrative authority by clarifying that the department director succeeds to all existing water management responsibilities without changing water rights, distribution rules, or policy. It directly affects water management operations under Arizona’s Department of Water Resources but does not alter water allocation or create new requirements. As a purely procedural update, it has no substantive policy impact.
