OPINION: California’s Next Water War Won’t Concern Agriculture. It Will Be About AI

For decades, California’s water debates have centered on a familiar tension: agriculture versus urban consumption. Agriculture, which consumes 80% of the state’s developed water supply, has long dominated discussions about conservation and efficiency. Yet, a new contender is emerging, one poised to dwarf agriculture in water demand and reshape the state’s water future: artificial intelligence (AI).

California’s agricultural sector is the backbone of the nation’s food supply, using approximately 34 million acre-feet of water annually — over 11 trillion gallons. This water sustains crops like almonds, grapes and rice, many of which are highly water-intensive and vital to the state’s economy. For decades, agriculture has been framed as the primary focus of water conservation efforts, with farmers frequently cast as both stewards and villains of California’s strained water resources.

 

Water Transfers, Conservation Partnerships Deliver Benefits to Regional Ratepayers

For the second year in a row, the San Diego County Water Authority and its partners have struck a deal to conserve water in Lake Mead, support the long-term sustainability of the Colorado River and save local ratepayers money. 

The agreements between the Water Authority, the Imperial Irrigation District, and the Metropolitan Water District, with funding from the U.S. Bureau of Reclamation, are designed to promote voluntary water conservation. The 2024 agreement was announced during a meeting of the Colorado River Board of California at this year’s Colorado River Water Users Association’s conference in Las Vegas.

Back-To-Back-To-Back Atmospheric Rivers Are Expected to Soak the West Coast

A barrage of storms known as atmospheric rivers is expected to soak the West Coast over the next eight to 10 days, raising the risk of flooding, power outages and holiday travel disruptions leading up to Christmas in a region that has already experienced significant weather activity this season.

The bulk of the rain and snow is likely to fall between British Columbia and Northern California, with Washington and Oregon poised to have some of the wettest, sloppiest weather.

South County Report: What’s in the Water

Sweetwater Dam rises 200 feet from the floor of a rocky river gorge a few miles northeast of Bonita. The 136-year-old concrete and masonry dam holds back 28,000 acre-feet of water in Sweetwater Reservoir, a major source of drinking water in South San Diego County.

The dam, and the reservoir, have been quiet fixtures of the Bonita and Spring Valley landscape for generations. These days, they’re drawing an unaccustomed amount of attention.

Lake Shasta Water Level Boosted by California Wet Weather, With More Rain Coming

Since last month’s atmospheric river that drenched the North State, the water level in Lake Shasta — California’s largest manmade reservoir — has shot up nearly 20 feet.

And after a few dry days this week, get ready for more rain in the northern Sacramento Valley as the region enters another wet pattern that is expected to go through Christmas.

San Diego Headed for Third Driest Start to Rainy Season in 152 Years

San Diego appears headed for the third driest start to the rainy season in at least 152 years, a streak that would further elevate the risk of wildfires in an already parched county, the National Weather Service says.

The city has recorded only 0.13 inches of precipitation since the season began on Oct. 1. If things remain unchanged through Dec. 31, the three-month period will officially be off to an unusually dry start.

Which States Mandate Fluoride in Drinking Water

President-elect Donald Trump’s pick to run the nation’s health agency, Robert F. Kennedy Jr., has railed against the practice of adding fluoride to drinking water, a measure that public health experts and dentists credit with reductions in tooth decay. Seven out of 10 Americans who get their drinking water from public water systems receive fluoridated water, according to data from the Centers for Disease Control and Prevention.

Toxic ‘Forever Chemicals’ Taint Rural California Drinking Water

Juana Valle never imagined she’d be scared to drink water from her tap or eat fresh eggs and walnuts when she bought her 5-acre farm in San Juan Bautista three years ago. Escaping city life and growing her own food was a dream come true for the 52-year-old.

Then Valle began to suspect water from her well was making her sick.

Crumbling Asbestos Pipes Deliver Drinking Water. Should We Be Concerned About a Cancer Risk?

Every month, Deacon Perry Owens Sr. estimates he spends at least $100 on bottled water. He doesn’t drink the tap water from his Emerald Hills home.

“It has a smell to it, a stench to it and we have tried every home remedy, and we can’t get rid of it,” he told Team 10.

Poway, Ramona to Study Feasibility of Sharing Water Resources

Ramona Municipal Water District and the city of Poway have entered into a memorandum of understanding (MOU) to look at the feasibility of sharing water resources.

Poway has been looking to diversify its water resources for the past 30 years, but the city is at a point where it needs to develop this.
