The Tucson AMA Fourth Management Plan (4MP) outlines the statutorily-mandated conservation requirements for agricultural, municipal, and industrial users within the Tucson AMA; it also discusses the region’s water management needs, and presents options for water users to achieve the Tucson AMA’s water management goals and objectives. The management goal of the Tucson AMA is achievement of safe-yield by the year 2025, and maintenance thereafter. ADWR will continue to work with the community in planning, providing technical assistance and managing regulatory programs that ensure a dependable water supply for Arizona’s future.
