About the Arizona Water Blueprint

Arizona Water Blueprint

The Arizona Water Blueprint is a data-rich, interactive map of Arizona’s water resources and infrastructure. Offering data visualizations and in-depth multimedia content on important water-related topics, the Water Blueprint is a tool for holistic thinking to inform policy decisions and good water stewardship.

The Colorado River

The Arizona CuRVE Project: Colorado River Visualization Enterprise

The goal of the Arizona Colorado River Visualization Enterprise (the "Arizona CuRVE Project") is to model the impacts to Arizona of Colorado River climate, hydrologic, and management scenarios. The CuRVE will visualize in an accessible way the potential effects of Colorado River shortages for individual community water systems, agricultural districts, tribal communities and industries across multiple years.

Water Research Publications

The Kyl Center for Water Policy at Morrison Institute regularly publishes research to inform water policy planning and decision-making.

Myth of Safe Yield

The Myth of Safe-Yield

If Arizona is to prosper into the next century, our focus needs to turn to what is essential for our future: The preservation of our groundwater and our increasingly fragile aquifers.

This analysis shows that Arizona continues on a path of unsustainable groundwater use that threatens the health and welfare of our state. It is not too late for a course correction, but that will require that Arizonans face the truth and make bold choices.

Return to Watering the Sun Corridor

Return to Watering the Sun Corridor

A lot has flowed under the bridge since August 2011 when the Morrison Institute issued "Watering the Sun Corridor," which addressed the understandable concern that urban Arizona might be “running out” of water.

Ten years later, land use attorney Grady Gammage Jr. reflects back on "Watering the Sun Corridor" in this new piece sharing his perspective about water supply and demand in Arizona's urban areas.

Elusive Concept Report Cover

The Elusive Concept of an Assured Water Supply

For nearly 40 years in its most urban areas, Arizona has prohibited the sale of new subdivision lots that lack a 100-year assured water supply. Originally, an assured water supply meant primarily renewable surface water. But in 1993, the Legislature changed course and created a new path to show an assured water supply using groundwater — a non-renewable resource — with the promise that the groundwater would be replenished with surface water acquired after the fact.

This report examines how this program — the Central Arizona Groundwater Replenishment District, or CAGRD — has worked over the last quarter-century and its consequences for water management and urban development in Arizona. We conclude that the unexpected popularity of the CAGRD has created serious challenges for good water stewardship and recommend changes in the CAGRD to ensure that homeowners in CAGRD have long-term water sustainability.

Meaning of the Colorado River shortage

The Colorado River Shortage and What it Means

Examining the Colorado River shortage and what it means for water conservation, residential water users, groundwater pumping, utility costs, urban growth, new water supplies, and water rights.

Ten Tenets of Water Equity

Ten Tenets of Water Equity

Water is the foundation of public health, economic opportunity, unique natural areas and quality of life in any community.

Much attention has been paid to the sustainable management of water supplies, as well as the responsible investment in the infrastructure that supports the delivery of safe, clean water.

In more recent years, issues regarding broad and fair access to safe, clean water in a community — water equity — have come into sharper focus.

Lessons from the Past report cover

Lessons from the Past

In 1995, the Arizona Legislature amended the state's adjudication statutes and other statutes that underlie surface water rights in Arizona. Those amendments led to five years of legal challenges that all but derailed the adjudication proceedings. In the end, the state Supreme Court ruled that most of the amendments were unconstitutional.

In 2020, the Legislature considered several measures that would impact surface water rights and the adjudications. To help inform the discussion of these proposals, the Kyl Center for Water Policy offered this analysis of what happened with the 1995 amendments.

The Price of Uncertainty Report Cover

The Price of Uncertainty

What water-related questions do people at the cutting edge of economic development ask when evaluating a site for potential investment?
