Irrigation Non-Expansion Areas (INAs)
The 1980 Groundwater Management Act established two Irrigation Non-Expansion Areas - Joseph City INA and Douglas INA. The Harquahala INA was created in 1981. The Phoenix AMA manages the Joseph City and Harquahala INAs. INAs have restrictions on increasing their number of irrigated acres.

Groundwater Users Advisory Council (GUAC)
Each AMA has a five-member advisory council appointed by the Governor as established by the Groundwater Code. Members are appointed for six-year terms to represent groundwater users in their respective AMA. Each Groundwater Users Advisory Council provides advice and recommendations to the AMA Director on groundwater management programs and policies within the AMA.
The Management Plans reflect the evolution of the Groundwater Code, moving Arizona toward its long-term water management goals. A series of five management plans prepared between 1980 and 2025 are to contain progressively more rigorous management requirements for agricultural, municipal and industrial water users. The five management plans cover the following years:
First Management Period 1980 to 1990
Second Management Period 1990 to 2000
Third Management Period 2000 to 2010
Fourth Management Period 2010 to 2020
Fifth Management Period 2020 to 2025
