Maui Water Department Begins Initial Planning for West Maui Desalination Plant

The Maui County Department of Water Supply is taking the first steps toward developing its first publicly owned desalination facility in West Maui. The project would extend the arid region’s water resources beyond current ground and surface water limitations that currently force the department to cope with a Stage 2 water shortage.

With a desalination plant, the department would have additional water resources to meet growing demand including direly needed housing developments, such as the 500-home Pulelehua project, which is currently stalled without available water.

California’s Water Year Is off to a Great Start. Here’s a Look at the Numbers

California’s water year is off to a great start, thanks in large part to the past week’s stormy stretch for the state. The water year began on Oct. 1 and continues until Sept. 30 next year.

Since the start of the water year, Sacramento has seen nearly 5 inches of rain at Executive Airport. That is more than three times the normal amount of rain for this point in the season.

How California Water Can Navigate a Changing Federal Partnership

Feelings were running high—and interest was evident—as hundreds of people turned out for our fall conference last week in Sacramento. The lunchtime program featured a panel of five experts representing water interests from across the state.

The day opened with a short video celebrating the PPIC Water Policy Center’s first 10 years, followed by a welcome by center director Letitia Grenier, who thanked the audience for braving the rain to attend. “An atmospheric river decided to come to our water conference this year, which is very on-brand,” she said with a smile.

U.S. Data Centers Could Consume as Much Water as 10 Million Americans by Decade’s End

When Cornell University systems engineer Fengqi You started modeling the environmental footprint of data centers three years ago, the A.I. boom was just beginning. Even then, You and his colleagues noticed something missing from the conversation.

“When we started this, we saw that A.I. was growing very fast,” You said. “It was clear it would have to be aligned with power-grid planning, with water and other resource planning. There were no discussions about these topics — but we wanted to bring real numbers, rigorous analysis on A.I.’s physical footprints.”

November Deluge Breaks Rainfall Records. New Storm Will Bring Snow to Southern California

Since Oct. 1, downtown L.A. has gotten 4.14 inches of rain, quite a bit more than the average 0.89 inches. For November, the average over the last 30 years is just 0.78 inches, but we’ve had 2.82 inches so far. This is currently the 19th wettest November since 1877, and given that there’s more rain to come, this could become one of the top 10 starts to a rainy season.

Another storm going to drop between a half-inch and 1 inch of rain across much of the area, and as much as 2 inches in the mountains. Several inches of snow could fall above 5,000 feet. Downed trees and minor debris flows are possible as strong winds and concentrated downpours pass through the area. We could see rain on Thursday and Friday as well, but the forecast is a bit uncertain. Next week things should dry out and warm up, with temperatures climbing into the 70s and 80s.

A California City’s Groundbreaking Path to Water Self-Sufficiency

On Main Street in Santa Monica, Calif., a parking lot sits between the courthouse and a boarded-up convention center. Visitors looking for a parking spot or charging their electric vehicles would never guess that a world-class water management system churning out millions of gallons of purified water sits underneath it.

The city’s Sustainable Water Infrastructure Project (SWIP) is a state-of-the-art water recycling system that has helped bring Santa Monica 85 percent of the way to complete water self-sufficiency. Groundwater from the Santa Monica Basin is the major source of supply for the city, augmented by purchases from the Metropolitan Water District of Southern California. In 2011, the city was importing almost half its water, generating fears about what officials would do in case of an emergency.

Recent Rain Boosts Early Totals for 2025-26 Water Year in Northern California

A late fall storm that soaked the North State and brought high wind gust is padding rain totals for what has been a wet start to Northern California’s water year.

As of Wednesday, Nov. 12, the Redding Regional Airport had received 4.24 inches of rain since Oct. 1, which was the start of 2025-26 water year, according to the National Weather Service.

OPINION: As Trump Sends California Water to Farmers, Native Salmon Face Extinction

California’s wild salmon have faced just about every obstacle imaginable over the decades as they now cling to survival. Dams have blocked where they are supposed to spawn. Levees deny young fish the floodplain for feasting. Pumps send them in deadly wrong directions.

But all the previous man-made threats to the salmon have nothing on President Donald Trump.

 

Officials Celebrate Much-Needed Recovery of Crucial U.S. Water Supply: ‘We’re Doing Really Well’

Oregon water managers are celebrating an exciting milestone this fall. Owyhee Reservoir is ending its irrigation season with 170% of its 35-year average water volume, which is a sign of much-needed stability for local farmers and communities.

Capital Press reported that officials say the reservoir’s healthy levels are great news for the coming seasons. When the irrigation season closed on October 10, the reservoir held 357,000 acre-feet of water — nearly double what’s typical for the time of year.

Atmospheric River to Soak SoCal, Rain Pushes Into the Weekend

After a hot start to the week, we are prepping for a significant storm as models give us a better idea of what to expect.

An atmospheric river will bring periods of heavy rainfall and mountain snow, gusty winds and thunderstorms to California mainly Friday and Saturday in Southern California.
