OPINION: How to Achieve Water Abundance in California

A study released in May, The Magnitude of California’s Water Challenges, anticipated annual statewide water supply losses in the coming decades as follows: ending groundwater overdraft 2-3 million acre-feet (MAF), less from the Colorado River 0.5-0.8 MAF, climate change 1-3 MAF, and increases to required environmental flows 1-2 MAF. The total losses? 4.6 to 9 MAF per year. It’s easy enough to quibble over these estimates, but a more productive response is to propose ways we can sustainably harvest more water in California. So that’s what we have done.

How Have California’s Water Issues Changed in the Past Thirty Years?

Back in 1994, Ace of Base and Boys II Men were chart-topping artists, “The Lion King” was the year’s most popular movie…and the Public Policy Institute of California drew its first breath. A lot has changed in California since then, so we sat down with key PPIC Water Policy Center staff to discuss what’s changed—and what hasn’t—in the California water world since the year the White House launched its first webpage.

Senate Passes California Water Infrastructure and Ecosystem Restoration Priorities

Today, U.S. Senator Alex Padilla (D-Calif.), Chair of the Environment and Public Works Subcommittee on Fisheries, Water and Wildlife, announced that he secured several top water infrastructure priorities for California through the unanimous Senate passage of the Thomas R. Carper Water Resources Development Act (WRDA) of 2024. The legislation includes provisions Padilla fought for to address the Tijuana River transboundary sewage crisis, to invest in salmon recovery and habitat restoration around the Sacramento River Basin, and to provide the Army Corps of Civil Engineers with enhanced drought and flood control authorities.

The Senate and House of Representatives have each passed their respective versions of WRDA, which will now be conferenced to produce final legislation.

Will Global Warming Turn L.A. into San Bernardino? Map Models Climate Change in 60 Years

Imagine it’s a Saturday morning in Santa Monica in the year 2080. You brew your coffee, open your front door and breathe in the hot, dry air of … San Bernardino?

That’s the potential future if climate change continues unabated, according to a new mapping tool from researchers at the University of Maryland Center for Environmental Science. The tool draws direct lines between an area’s projected climate in 60 years and the places that are experiencing that climate today.

Heat Wave, Thunderstorms to Raise the Risk of Wildfires in California

Another heat wave and more monsoonal thunderstorms are expected to increase wildfire danger in California over the weekend and into next week.

A high-pressure system is expected to expand over the western United States on Wednesday and get stronger through Friday, according to the National Weather Service. California will be spared the worst of the heat, the weather service predicted, as the system concentrates over the Rocky Mountains.

State Water Project Supplies Could Fall up to 23% Within 20 Years Due to Climate Change

Climate change threatens to dramatically shrink the amount of water California can deliver over the next 20 years and could reduce supplies available from the State Water Project by up to 23%, according to new projections released Wednesday by Gov. Gavin Newsom’s administration.

The analysis by the California Department of Water Resources examined a range of climate change scenarios and projected that by 2043 the average amount of water transported through the massive network of reservoirs and canals to more than half the state’s population could decline between 13% and 23%.

OPINION: Californians Will Have to Use Less Water Under State Board’s New Rules

It’s been said in different ways by a variety of people, but there’s more than just a grain of truth in it: If the federal bureaucracy or a socialist regime were ever put in charge of the Sahara Desert, there would eventually be a shortage of sand. This helps explain why there is such a scarcity of water in California that permanent use restrictions have been, for the first time in the state’s history, set.

On July 3, the California State Water Resources Control Board approved the rules for “Making Conservation a California Way of Life.” Under this framework, retail water suppliers are going to have to figure out how to meet the imposed “water use objective,” which “is 70% or less of the supplier’s average annual water use” in 2024-26 by July 2040.

OPINION: California Could Lose up to 9 Million Acre-Feet of Water by 2050. Here’s What Can be Done

California’s water supply is trending poorly. Unless we act now to transform how California manages its water — by passing an important bill that would update our approach — the state will soon lose some of its year-to-year supply.

By 2050, California is expected to lose between 4.6 and 9 million acre-feet of its annual water supply. In other words, by 2050 at the latest, Californians would lose access to a volume of water that is enough to supply 50-90% of all the state’s households — or to irrigate 17-33% of all the state’s farmland. Picture a volume of water as large as two Lake Shastas disappearing from the state’s water bank.

The American West’s Last Quarter-Century Ranks as the Driest in 1,200 Years, Research Shows

Three years ago, climate researchers shocked drought-weary Californians when they revealed that the American West was experiencing its driest 22-year period in 1,200 years, and that this severe megadrought was being intensified by global warming.

Now, a UCLA climate scientist has reexamined the data and found that, even after two wet winters, the last 25 years are still likely the driest quarter-century since the year 800.

Water (and its Absence) Looms Large in the California Mind. Here are 6 Ways to Make the Most of it

There are three go-to topics of conversation for Angelenos: weather, traffic and water. Our city is perpetually trying to rid itself of H20 or thirsting for it. Those opposing needs shaped L.A.’s topography and made a mythic king out of a self-taught engineer from Belfast. And recent drought has forced us to confront the reality of climate change, rethink our water sources and dig up our lawns.

Given how large water supply looms in the minds of Californians, our access to it in L.A. feels especially miraculous, and — during the relentless radiating heat of summer — uniquely enlivening.
