Biden Pursues Reversal of Rules for Water Projects

The struggle over management of water supplied through the Sacramento-San Joaquin Delta continues as the Biden administration seeks a reversal of rules put in place by agencies under the Trump administration.

Last week, the U.S. Bureau of Reclamation sent a letter to federal fisheries agencies and announced it is reinitiating consultation of the U.S. Fish and Wildlife Service and National Marine Fisheries Service 2019 biological opinions related to the coordinated, long-term operation of the Central Valley Project and State Water Project.

The two water projects are California’s primary water-delivery systems that guide pumping of water through the Sacramento-San Joaquin Delta, sending water south to tens of millions of people and to millions of acres of farmland.

Atmospheric Rivers Are Stable For Now — But Change Is On The Way

Yale researchers are charting the course of mighty “rivers” in the sky that are holding steady in the face of climate change — for now.

In future decades, however, climate-induced changes to these atmospheric rivers could drastically increase extreme precipitation events in some parts of the world, they report in a new study published in the journal Nature Climate Change.

Atmospheric rivers — long, winding filaments of intense water vapor — account for as much as 90% of the moisture sent toward the North and South poles.

White House Launches Climate Initiatives to Arm Communities Against Floods, Extreme Weather

The White House announced Tuesday that it would work to revise building standards for flood-prone communities across the country in the face of climate change, while launching tools to make climate information more accessible to the public.

The move is part of the Biden administration’s broader effort to push the United States to reckon with the costs of global warming by factoring in the long-term consequences of decisions being made today.

Water Authority Wins National 2021 EPA WaterSense Excellence Award

The U.S. Environmental Protection Agency has recognized the San Diego County Water Authority with a 2021 WaterSense Excellence Award for advancing water efficiency through its Qualified Water Efficient Landscaper, or QWEL, program. The Water Authority received one of 34 WaterSense awards last week at the national WaterSmart Innovations Conference in Las Vegas.

How to Beat the Drought? Inland Empire Water Agency Wants to Make it Rain

Programs from the drought-busting handbook practiced by Southern California water agencies include recycling water, building storm-water capture basins and offering cash rebates for replacing thirsty lawns with xeriscape landscaping.

With the grip from a second year of drought tightening, a regional water-planning agency in the Inland Empire is moving ahead for the first time in its history with a more controversial program: cloud seeding.

Are Two More Dry Years Ahead For California?

Water use in Manteca increased 3 percent overall or 13.6 million gallons last month compared to the depth of the last drought in September of 2017. That’s good news given the city has added more than 8,000 residents since Jan. 1, 2017 for a 10 percent population gain. The bad news it might not be enough. Despite a light dusting of snow Thursday along the high Sierra crest at the upper reaches of the Stanislaus River watershed critical to urban and agricultural users in South San Joaquin County, hydrologists are indicating a number of weather models don’t look promising.

How Much Is Water Worth? Why A Billionaire-Owned Stake In A California Water Bank Could Be Worth More Than $1 Billion

How much is access to water worth? In this episode, we aim to answer that question by looking at the Kern Water Bank, one of California’s largest underground water storage facilities. From above, it looks a lot like a giant puddle. But underneath it has the capacity to hold the equivalent of roughly 500 of New York City’s Central Park Reservoirs. And, as one expert says, it’s the “absolute jewel” of California water banking.

‘Extreme Year’: Past 12 Months Among the Driest Ever in California History

The current ongoing two-year dry period in California, punctuated by the third-driest water year on record for the Central Sierra, is part of California’s overall arid fate so far in the 21st century, according to the state Department of Water Resources.

The Golden State’s hydrology now increasingly resembles conditions in the Colorado River Basin this century, where multiple, consecutive, drier-than-average years are mixed with an occasional wet year. California’s last wet water year was 2016-2017, the second-wettest on record.

Lake Tahoe Falls to Alarmingly Low Level – Environmental Impacts Could Result

This week, a historically dry period in California will come to bear at Lake Tahoe, where the water level is expected to sink below the basin’s natural rim. That’s the point at which the lake pours into its only outflow, the Truckee River.

It’s not a crisis, researchers and conservationists say, but it marks another extreme swing for Tahoe amid historic drought, wildfires and erratic weather, all intertwined with climate change and becoming more prominent aspects of the alpine environment.

Why Southern California Fears Too Much Water Conservation

As Gov. Gavin Newsom weighs new mandatory drought restrictions, Southern California leaders fear cuts in urban water use could force already sky-high water bills ever higher.

Unlike much of Northern and Central California, the region isn’t hurting for water, yet. Top water officials insist they have enough supplies for at least one more hot summer, perhaps two.
