How Wildfires Are Threatening Colorado Water Supplies — and Costing Lots of Money

The Colorado River this spring ran high, fast and so full of sediment pushed downstream from wildfire burn scars that the water treatment plant in Hot Sulphur Springs couldn’t keep up.

The sediment repeatedly clogged the town’s intake valves, forcing town leaders to issue and emergency order in April and call for residents to voluntarily cut back on water use.

Low-Income LADWP Customers’ Bills Are About to Rise. What Help is Available?

As Angelenos wither under another hot summer, the Los Angeles Department of Water and Power is shrinking a discount program that helped low-income families pay their bills.

The utility has no choice; the subsidies that funded the DWP’s discounted water rates were declared illegal by a Superior Court judge in May. That discount will disappear Thursday, although others will remain in place, the DWP said in a letter to customers.

Water Wasted | The History of the Delta Water Tunnel Project and Why People Are Against It

A battle remains underway in the Sacramento-San Joaquin Valley Delta.

For decades, Delta residents and the state have been unable to agree on a plan to transport water from the rainy but rural northern part of the state down to the heavily populated, dry southern half.

How Cloud Seeding is Giving a Boost to Nevada’s Water Supply

In mountain peaks across the West, it’s their job to make it snow.

No, they’re not wizards, even if the work they do seems like magic.

Water Authority Defectors Survive Second Round of Legal Threats

Tensions seem to be cooling slightly between the San Diego County Water Authority and those that want to leave it.

Two small North County farming communities survived a second round of attempts by the Water Authority to wage a legal war against their divorce from the regional water supplier.

A Relentless Heat Wave That Refuses to Let Up Brings Danger to California, Southwest

For nearly a month, millions of people across the American Southwest have sizzled, sweated and sweltered under a heat wave that refuses to let up.

Day after day, residents from Fresno to Phoenix have endured triple-digit temperatures and hot, restless nights that have offered little relief.

Helix Water District Named Water Energy Leader with Energy Use Reductions

Helix Water District received recognition from The Climate Registry as a Water-Energy Leader Gold organization after the district reduced its electric use by 15% and greenhouse gas emissions by 40%.

The Climate Registry is a nonprofit organization that helps companies, governments, and institutions reduce their emissions.

July Has Been So Blistering Hot, Scientists Already Calculate That it’s the Warmest Month on Record

July has been so hot thus far that scientists calculate that this month will be the hottest globally on record and likely the warmest human civilization has seen, even though there are several days left to sweat through.

The World Meteorological Organization and the European Union’s Copernicus Climate Change Service on Thursday proclaimed July’s heat is beyond record-smashing.

Everything, Everywhere, All at Once: The Great Floods of 2023

Another week, another catastrophic, record-setting, history-making flood, this time in Kentucky.

Preliminary assessments indicate rainfall in Graves County last week likely set a new record for most precipitation in a 24-hour period, with 11.28 inches of rain. This would make it yet another “1,000-year” flood event, which had, according to historical projections, less than a 0.1 percent chance of occurring in any given year. One of the towns that experienced flash flooding was Mayfield, a community still rebuilding from a 2021 tornado that killed 57 people.

This was just one of the 11 flash flood emergencies in as many days in the United States, according to Weather Channel meteorologist Heather Zons. These events have claimed multiple lives: 2-year-old Mattie Shiels, 9-month-old brother, Conrad, and their mother, Katie Seley drowned after getting swept away by flash flooding in Pennsylvania, during an event that killed at least four others. In New York earlier this month, 43-year-old Pamela Nugent was swept away trying to evacuate a flooded area; 63-year-old Stephen Davoll drowned in his home in Vermont.

How Much Snow Still Covers California’s Mountains This July?

In a typical year, California mountains are largely snow-free at this stage in the summer, with some exceptions at higher elevations. This, however, has not been a typical year. In the last couple of weeks of July, large swaths of the Sierra continued to be covered in snow, making for tricky and in some cases treacherous hiking conditions.
