The proposed bill would amend current statutes by requiring the Director of the Arizona Department of Water Resources to include specific data in each five-year water supply and demand assessment for groundwater basins. The current law mandates that the Director prepare and issue an assessment for at least six of the fifty-one groundwater basins annually, ensuring that all basins are assessed at least once every five years. The bill introduces new requirements for the assessments, including metrics such as average depth-to-static level, net changes in groundwater levels, maximum bedrock depth, and the total estimated volume of groundwater in storage, among others.

Additionally, the bill makes technical changes to the existing language, such as updating the timeline for assessments and clarifying the data to be included. The current requirement for assessments to be completed by December 1 of each year is modified to specify that the Director must include the outlined data in each five-year assessment. Overall, the bill aims to enhance the comprehensiveness and accuracy of groundwater assessments in Arizona.
