Arizona officials would assess groundwater basins and track supplies

The water resources director would prepare yearly water supply and demand assessments and include specified measurements in five-year assessments for each groundwater basin. Each year, the assessments must cover at least six of Arizona’s 51 groundwater basins. Every basin and initial active management area must receive an assessment at least once every five years. The director may hire outside entities to complete some or all of the assessments and must identify them in the assessment. The yearly assessment is due on or before December 1 of each year. Each basin and initial active management area must be assessed at least once every five years.
