Texas Water Resources Institute

Texas Water Resources Institute TWRI provides science-based, community-supported solutions for Texas' pressing water challenges.

Securing and managing sufficient, healthy water is one of the most significant challenges facing Texas today. Major water quantity and water quality problems exist, and solutions are needed to support economic growth, ecological sustainability, public health and continued food production across the state. At TWRI, we help solve these pressing water challenges by providing needed expertise and developing strong, interdisciplinary partnerships. We also deliver important water information to citizens and professionals. Our work centers around the following three areas:
• Water Quality Improvement
• Water Sustainability and Security
• Water Resources Outreach and Training

Yesterday, we were thrilled to gather together with leaders from Texas A&M AgriLife Research, TWRI, and the UNAM Universidad Nacional Autónoma de México to sign a memorandum of understanding to formally begin collaborative research and educational programs.

“We are honored to begin officially partnering with our colleagues at UNAM,” said Giovanni Piccinni, Ph.D., TWRI director. “Texas and Mexico face many common challenges in water, agriculture, and energy. With so many outstanding researchers on both sides of the border, we believe that we can build strong research and education collaborations that benefit both the U.S. and Mexico.”

José Antonio Hernández Espriú, Ph.D., director of the School of Engineering at UNAM, and Saúl Arciniega Esparza, Ph.D., UNAM associate professor of engineering and hydrogeology, represented UNAM, and Cliff Lamb, Ph.D., director of Texas A&M AgriLife Research, represented Texas A&M AgriLife Research. They were joined by leaders from the Texas A&M Energy Institute, Texas A&M University Department of Horticultural Sciences, Texas A&M AgriLife Extension Service, and TWRI.

How can land management affect water utilization? And how can you create a system that’s most beneficial for you and your land? Program specialist Mary Michael Lipford Zahed answers these questions while demonstrating the rainfall simulator at a Texas Watershed Stewards Workshop.

Earlier this week, TWRI Program Specialist Madeleine Spencer attended a Texas Parks and Wildlife Department mussel mark-recapture sampling event in Brushy Creek.

The survey was led by TPWD's Clint Robertson, with support from other agencies and organizations across Texas. 2026 is year three of this study, which is surveying a section of the creek for mussels that were previously captured and attached with a PIT tag, as well as new mussels that are now using this habitat. This practice helps to better understand how changes in the creek impact the mussel population over time.

Brushy Creek is also currently in the watershed protection plan (WPP) development process, and TWRI is helping facilitate that process with local leaders and residents. The next Brushy Creek Watershed Partnership stakeholder meeting is September 23 in Round Rock and open to all interested residents.

We’re excited to see TWRI Associate Director Allen Berthold, Ph.D., named to the newest cohort of the LEAD AgriLife program!

This leadership development program brings together exceptional leaders from across Texas A&M AgriLife, and we’re proud to see Allen represent TWRI as he takes part in this year’s cohort. We look forward to seeing the opportunities, connections and leadership growth that come from this experience: https://buff.ly/vDP5mI5

Have you ever wondered how and why groundwater is regulated the way it is in Texas? The particulars of Texas groundwater law and management were decided by key lawsuits and court rulings over the past 120 years, resulting in a complicated patchwork of precedents and guidelines.

These are some of the most influential groundwater court cases in Texas history, decisions that have shaped the Lone Star State’s legal stances on groundwater rights, management and access.
