California Plays ‘Hardball’ With Colorado River States Over Cutbacks

A multistate quest to protect a dwindling Colorado River has devolved into a high-stakes battle pitting California against its neighbors.

At odds are two dueling proposals as to how seven states should apportion critical consumption cuts that could help save the lifeblood of the Western United States.

In a Dramatic Spike, 36.3 Million Trees Died in California Last Year. Drought, Disease Blamed

Roughly 36.3 million dead trees were counted across California in 2022, a dramatic increase from previous years that experts are blaming on drought, insects and disease, according to a report by the U.S. Forest Service.

The same survey for 2021 counted 9.5 million dead trees in the state, but the effects of last year’s dramatic die-off are more severe and spread across a wider range, according to the report released Tuesday.

California Plans for the Good, the Bad and the Ugly About Snowmelt Runoff

Erratic climate swings—from drought to floods and back to dry conditions—are delivering less certainty to farmers for the coming irrigation season and a lot of misunderstanding about how much water is actually imported for food, electronics and other products.

Opinion: Western States Play Game of Chicken Over Colorado River

You would have to be at least a septuagenarian to remember “Rebel Without a Cause,” a 1955 movie that starred James Dean and depicted the lives of aimless teenagers.

The film’s most memorable scene was a game of chicken in which two boys raced cars side by side toward a cliff and the first one to bail out was the loser. The “winner,” however, died when his car hurtled over the cliff.

Wet La Niña Winter Likely to Bring More Water Into Lake Powell

One of the Colorado River’s two major reservoirs is expected to collect better than average runoff this year, thanks to an unusually wet La Niña pattern that dropped a deluge of snow up and down the basin.

Lake Powell, the nation’s second largest reservoir that sits on the border of Utah and Arizona, is expected to receive 117 percent of its average inflows as the heavy snowpack melts in the western Rockies during the all-important April through July time frame, said Cody Mosier, a hydrologist with the Colorado Basin River Forecast Center.

Why California is So Far Apart From Other States in Colorado River Water Cuts Plan

The ongoing dispute over Colorado River water comes down largely to math: How much water should each state and region lose as reservoir levels continue to decline?

California has one interpretation of how to divvy up the cuts, and six other states that depend on the river have a different formula.

Atmospheric Rivers Aren’t Just a Problem for California. They’re Changing the Arctic, Too

The Arctic is seeing a rapid decline in sea ice even during the cold winter months when it should be recovering from the summer melt. Scientists say that one often-overlooked factor is playing a bigger role than previously thought: Atmospheric rivers.

These long, narrow bands of moisture in the atmosphere transport warm air and water vapor from the tropics. They can extend for thousands of miles and dump rain and snow when they make landfall.

IID Partners With Mexican Consulate to Improve Canal Safety

The Consulate of Mexico in Calexico hosted a presentation Thursday, February 2 announcing a collaborative effort with the Imperial Irrigation District to raise awareness about the risk of the All-American Canal involving undocumented and illegal border crossings.

IID General Manager Henry Martinez opened by welcoming all in attendance and introducing dignitaries.

Ground Zero: Rain Brings Little Relief to California’s Depleted Groundwater

The powerful storms that clobbered California for weeks in December and January dropped trillions of gallons of water, flooding many communities and farms. But throughout the state, the rains have done little to nourish the underground supplies that are critical sources of California’s drinking water.

Thousands of people in the San Joaquin Valley have seen their wells go dry after years of prolonged drought and overpumping of aquifers. And a two-week deluge — or even a wet winter — will not bring them relief.

Rainmaking Experiments Boom Amid Worsening Drought

As rain clouds swelled over Fort Stockton, Texas, last summer, a little yellow plane zipped through the sky. It was on a mission.

Equipped with tanks of water and special nozzles on its wings, the craft soared beneath the gray-white billows. Then, at just the right moment, it released a spray of electrically charged water particles into the cloud.
