Within the state's Active Management Areas, cities, Tribes and other entities can accrue long term storage credits for groundwater stored in the aquifers. This tool provides details about each long term storage credit account -- how much water and where it is stored -- potentially facilitating exchanges of groundwater supplies among account holders.
Four of Arizona's Active Mangagement Areas (AMAs) have a goal of "safe-yield" -- a long-term balance between groundwater withdrawals and recharge. And yet four decades after that goal was adopted there is little expectation that any AMA will achieve safe yield over the long-term. This critical analysis examines the barriers to achieving safe-yield and offers recommendations for strengthening groundwater management in the AMAs.

The proposed Northeastern Arizona Indian Water Rights Settlement Agreement aims to resolve water rights for the Navajo Nation, Hopi Tribe, and San Juan Southern Paiute Tribe.
Access to affordable, safe drinking water is essential for public health and quality of life, yet many communities in Northern Arizona, particularly Native American and rural areas, face significant challenges in securing such access.
Arizona's 2023 groundwater model for the Phoenix AMA concluded that the region had reached the limits of physically available groundwater. This report explains the implications of that finding and what it means for continued development.
This report explains the legal connection between surface water and underground water in Arizona and the vulnerability of some water users within the Gila and Little Colorado watersheds to a finding that they are misappropriating surface water. In addition, the report explores how water rights uncertainty undermines both economic development and sustainable water management in many Arizona communities.
A general orientation to the main Water Blueprint map (our most comprehensive resource). Useful for anyone new to ArcGIS or the Water Blueprint.
Learn more about the "groundwater hotspots" within Arizona where there are significant concerns around underreported shrinking groundwater supplies.
Access to safe, reliable drinking water is the foundation of public health, economic opportunity and quality of life. Keeping water affordable is key to ensuring that it is accessible. But most community water system rely on revenues from rate-payers to cover operations and infrastructure cost. This report explains the tensions between keeping water affordable and recouping sufficient revenue to keep a public water system well-maintained. In addition, it analyzes the affordability of rates of over 600 Arizona community water systems.
