Overview

Expands the information required in the water supply and demand assessments of groundwater basins.

History

The Arizona Department of Water Resources (ADWR) Director is required to prepare and issue, not later than the first of December each year, a water supply and demand assessment for at least six of the 51 groundwater basins in the state. The ADWR Director must ensure that a water supply and demand assessment is completed for all groundwater basins and initial active management areas (AMAs) at least once every five years. The ADWR Director is allowed to contract with outside entities to perform some or all of the assessments so long as said entities are identified in the assessment (A.R.S. § 45-105).

Provisions

1. Requires the ADWR Director include, in a five-year supply and demand assessment, the following:

a. average depth-to-static level at the end of the assessment period, along with average net increase or decrease;

b. maximum and average bedrock depth at the deepest point;

c. total number of active index wells;

d. average distance between active index wells;

e. average geographic distribution or density of active index wells;

f. total volume of, and total number of years' worth of groundwater available to its maximum depth at the end of the assessment period;

g. total number of active and passive stormwater and groundwater recharge projects; and

h. total volume of increased groundwater recharged due to active and passive stormwater and groundwater recharge projects in each of the five years preceding the end of the assessment period. (Sec. 1)
