Arizona DCP Implementation Plan

As Arizona transitions to a drier future, we must continue to promote a culture of

conservation - one that enables the unbeatable quality of life and boundless

opportunity we enjoy.

Governor Doug Ducey Signs Arizona DCP Legislation

Jan. 31, 2019

Arizona’s Future

• Reconsultation to begin by Dec. 31, 2020

• States will lead as they did in the 2007 Interim Guidelines

• Arizona participants likely to expand

• Basin states yet to discuss scope of new guidelines

• 2007 guidelines + DCP – Lessons learned

• Expect reductions in Arizona to be unmitigated
