Hualapai Valley INA

UPDATE: The Arizona Court of Appeals has stayed the
Superior Court’s judgment in the Hualapai Valley INA

On June 11, 2026, the Court of Appeals conducted a hearing and granted a stay of the Maricopa County Superior Court’s judgment, which had invalidated the Director’s Final Order Designating the Hualapai Valley INA. The stay will remain in place during the appellate special action unless and until the Court of Appeals takes further action on it after reviewing Respondents’ response to the motion for stay.

This means that the Director’s Final Order Designating the Hualapai Valley INA and related statutory irrigation restrictions currently remain in place. Under A.R.S § 45-437(B), only acres that had been irrigated within the five years preceding the initiation of the procedures to designate the INA (October 12, 2022) may be irrigated. The irrigation of new acreage after October 12, 2022 is prohibited.

Any updates to the stay order and decision of the Court of Appeals will be posted on ADWR’s Hualapai Valley page, here. Court filings can be found in the Cases of Interest section of ADWR's Laws Rules and Policy page.

On June 23, 2022, the Mohave County Board of Supervisors requested that the ADWR Director take “whatever actions available and necessary to designate the Hualapai Valley Groundwater Basin as a subsequent INA."

By letter dated June 24, 2022, the Director indicated that ADWR would review updated modeling and other relevant information, including current and projected drought conditions and receive public comments on whether to initiate designation procedures.

On September 20, 2022, ADWR held a public meeting to present information and receive comments regarding whether the Director should initiate procedures to designate the Hualapai Valley Groundwater Basin as an INA.  Based upon hydrologic information and public comments received, the Director signed an Order to initiate procedures to designate the Hualapai Valley Groundwater Basin an INA on October 12, 2022.  In the same Order the Director also ordered a Public Hearing to hear evidence both orally and written.

On November 12, 2022, the Department held a Public Hearing and presented the factual data in its possession in support of or in opposition to the proposed subsequent irrigation on-expansion area, pursuant to A.R.S. § 45-435(C).
