A recent study led by researchers at the University of Arizona finds that human groundwater pumping has played a larger role than long-term climate variability in depleting groundwater in southern Arizona.

On January 13, the US Geological Survey (USGS) hosted a webinar demonstrating how to access and use new modeled water data delivered through the National Water Availability Assessment Data Companion (NWDC).

The WRRC is now accepting applications for two paid internships for Summer 2026. Both are open to current undergraduate and graduate students who will be enrolled at the U of A in the Fall 2026 semester. Applications for both are due March 9, 2026. Any eligible student may apply for either or both internships. Students applying to both internships must submit separate applications for each internship.

After receiving approval from the Arizona Department of Water Resources last month, the Central Arizona Groundwater Replenishment District (CAGRD) has announced the release of its 2025 Plan of Operations.

The WRRC is pleased to announce that, thanks to a generous sponsorship from Cooperative Extension, a limited number of complimentary conference registrations will be available for Extension employees and will be awarded on a first-come, first-served basis.

Our wonderful students have returned to work at the WRRC for the Spring 2026 semester, several of whom will be giving brief talks about their projects at our upcoming Chocolate Fest on February 12. Please join us to learn more about the cool work they’ve been doing!

The WRRC is pleased to welcome two new Graduate Research Assistants, Lynn Carroll and Caleb Dusek. Lynn will be working on Water RAPIDS projects, including our upcoming WIFA conservation factsheet series. Caleb will help with communications and outreach for the WRRC Annual Conference and other WRRC programs, as well as providing assistance on various research projects.

Registration for the WRRC 2026 annual conference opens today! This year’s conference, Water for Tech, Mining & Energy: Pathways to Arizona’s Future, will be held April 14–15 at the U of A Student Union Memorial Center in Tucson, Arizona. The program will explore the challenges and opportunities for water stewardship among Arizona’s key non-agricultural water use sectors, including mining, energy, and technology. Sessions will highlight innovative strategies, best practices, regulatory frameworks, municipal–industrial partnerships, and environmental considerations shaping Arizona’s water future.

The Arizona Department of Water Resources (ADWR) has designated the Ranegras Plain Groundwater Basin Arizona’s eighth Active Management Area (AMA). This designation follows the determination by ADWR Director Tom Buschatzke that the basin is experiencing severe groundwater declines.

The Bureau of Reclamation has released a draft Environmental Impact Statement (EIS) examining five options for operating Colorado River reservoirs after 2026, when current operating agreements expire.
