The ANSAC Commissioners believe everyone should be a good steward of the environment and ANSAC's mission is twofold, to determine the navigability of Arizona's 39,039 watercourses as of statehood February 14, 1912 for streambed title purposes, and to determine the public trust values of all watercourses that were navigable at statehood.

ANSAC's mission relates only to matters regarding streambed title.  Issues dealing with water use  or water rights are not within ANSAC's authority.

ANSAC has compeleted the largest part of its mission which includes multiple evidentiary navigability hearings held in every county seat.  The final hearing was comploeted on the Verde River. Throughout its history including various transformations, ANSAC has conducted more than 130 total hearings, with hearings held in every Arizona county so local citizens may participate.  Through this process ANSAC has adjudicated the navigability of approximately 39,039 watercourses. ANSAC is presently in the reports, research, writing and Superior Court Appeals phases of its work, with six appeals pending in state court: Lower Salt River, San Pedro River, Santa Cruz River, Upper Salt River, Verde River, and Gila River. 

ANSAC attempts to keep office hours flexible to provide optimum service to our customers by being available for the review of evidence at almost any time including to out of state visitors.  Prior arrangements are necessary partly to insure two opposing parties do not want to review the same evidence at the same time.
