The Southwest’s next source of water might be gurgling through the sewage pipes under this corner of Los Angeles County, an untapped stream in a Colorado River Basin that is otherwise tapped out. Indirectly, Arizonans are poised to reap the benefits of a plan to recycle the last drops from a river that begins as Rocky Mountain snow but ends as treated wastewater dumped into the Pacific Ocean.
A record number of water wells in California have gone dry as climate change amplifies heat and drought in the parched state. Residents reported having 1,394 dry wells statewide from January through last month, an increase of nearly 40 percent from the same time last year. It’s the highest number since the start of record keeping in 2013.
An insidious category of carcinogenic pollutants known as “forever chemicals” may not be so permanent after all. University of California, Riverside, chemical engineering and environmental scientists recently published new methods to chemically break up these harmful substances found in drinking water into smaller compounds that are essentially harmless.
Reformist farmers in California have deposed the leader of the country’s biggest irrigation district, who was known for fighting water regulations. Farmers are accepting less water means less farming. A local election in rural California caught our attention last month. Farmers ousted the longtime leaders of the organization that supplies their irrigation water, which may sound small, but as Dan Charles reports, it’s a sign of something bigger – farmers reacting to a hotter climate.
Winter storms that doused California with much-needed rain and snow over the last week have managed to ease some dire drought conditions, but experts warned that the state still has a long way to go to truly reverse its historic dry streak. For many, the massive storm system that soaked swaths of the West Coast with inches of rain and feet of snow was a reminder of seasons past as it snarled traffic, triggered rock slides and sparked a blizzard of “winter wonderland” posts on social media.
As Western water managers get set to gather in Las Vegas this week, a long-sought deal to curtail water use along the cratering Colorado River still seems a ways off. Nearly six months have passed since Bureau of Reclamation Commissioner Camille Touton first asked the Western states to come up with a plan to cut back on water use from the river next year by as much as 30 percent, but a cohesive proposal from the seven states that pull from the Colorado that supplies water to some 40 million people has yet to emerge.
For the second weekend in a row, Sacramento and the Sierra Nevada mountains saw back-to-back storms bringing rain to the valley and snow to the hills. Despite the recent wet weather, including snow intense enough to snarl mountain travel in the Sierra this weekend, California is still grappling with a number of drier-than-usual winters and persistent drought. So how much did these storms help?
December has delivered a powerful punch of storms to California. But the wet weather comes with a dry dose of reality: The state’s largest reservoirs remain badly depleted, projected water deliveries are low, wells are drying up, and the Colorado River’s water, already diminished by a megadrought, is severely overallocated. Throughout California, urban water managers are bracing for a fourth consecutive drought year.
Management of the depleted Colorado River needs an overhaul, speakers at a University of Arizona-sponsored conference agreed. But at a conference called last week to observe the 100th anniversary of the interstate compact that divided river water rights among Western states, the speakers disagreed over whether the Colorado River Compact itself needs a major rework.
Living with less water in the U.S. Southwest is the focus this week for state and federal water administrators, tribal officials, farmers, academics and business representatives meeting about the drought-stricken and overpromised Colorado River. The Colorado River Water Users Association conference, normally a largely academic three-day affair, comes at a time of growing concern about the river’s future after more than two decades of record drought attributed to climate change.
