The depletion of groundwater resources, driven by unsustainable agricultural practices and increasing demands for food production, is a pressing issue, and it  underscores the urgent need for sustainable groundwater governance.

The amendment to a 1944 treaty will help Mexico catch up with its water deliveries to the U.S. and might help Rio Grande Valley farmers devastated by low rainfall.

Four rural Arizona county supervisors are asking for more regulation when it comes to pumping rural groundwater, something that their constituents denied them in 2022.

Major water reservoirs across the continental United States are experiencing longer, more severe, and more variable periods of low storage than several decades ago, a new study reports. The problems are most severe in the western and central United States, but reservoirs in the eastern and southeastern United States are not immune.

Reviving the LA River is a prime example of a large-scale infrastructure project that requires engineers to work alongside nature and society. A revived LA River can again serve as habitat for native vegetation and wildlife, improve water quality, aid water management, and contribute to cultural renewal.

Many of the solutions are costly, putting them out of reach for small towns. But the region’s most populous cities are getting innovative.

El Vado is an odd dam: It’s one of only four in the United States that uses a steel faceplate to hold back water, rather than a mass of rock or concrete. The dam, which is located on a tributary of the Rio Grande, has been collecting irrigation water for farmers for close to a century, but decades of studies have shown that water is seeping through the faceplate and undermining the dam’s foundations. Cities across the West rely on fragile water sources — and aging infrastructure.

As the Biden administration attempts to gain support for breaching hydroelectric dams in Washington, state and federal agencies are preparing for a study on the potential implications.
