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. 

in this region of Kansas where water is everything, they’ll have to overcome entrenched attitudes and practices that led to decades of overpumping. After decades of local inaction, Kansas lawmakers are pushing for big changes in irrigation.

A new study maps how energy and food systems depend on stored water to generate hydropower and feed irrigation. Dams and reservoirs won’t be able to meet the demand in coming decades.

Sustaining the American Southwest is the Colorado River. But demand, damming, diversion, and drought are draining this vital water resource at alarming rates. The future of water in the Southwest was top of mind for participants and attendees at the 10th Annual Eccles Family Rural West Conference.

The Colorado River, “the lifeblood of the West,” is in trouble. Decades of overuse and drought have sharply reduced its water supply, threatening an ecosystem that supports 40 million people and 5.5 million acres of farmland. Stanford economist Paul Milgrom won a Nobel Prize in part for his role in enabling today’s mobile world. Now he’s tackling a different 21st century challenge: water scarcity.
