Global warming has already left its mark on the backbone of California’s water supply, and represents a growing threat to its first developed agricultural region, state experts have warned in a new study.
The Sacramento-San Joaquin Delta fuels California’s $3 trillion economy, including its $50 billion agricultural industry, sustains more than 750 plant and animal species and supplies 27 million people with drinking water.
Climate change is exacerbating droughts and accelerating the transformation and decline of California’s native forest and aquatic ecosystems. As a state, we are poorly organized to manage these effects, which need extensive focused preparation. We need to adapt (and we will make mistakes in doing so). Our human, economic and environmental losses will be much greater, however, if we manage poorly because of delay, complacency or panic.
Farmers are facing a water shortage right as we head into peak growing season. It’s hitting their bottom line — and potentially yours.
Solano County farmer Spencer Bei shows us one of the wells his family uses to farm 15,000 acres. He says he is losing pressure now as he is pumping because he is pulling more from the aquifer due to a lack of surface water and no rain in sight.
To finally determine a lasting definition of waterways that qualify for federal protection under the Clean Water Act, the Environmental Protection Agency’s new water director says everyone with a stake in the issue will need to be engaged.
Radhika Fox recently spoke to The Associated Press about the Biden administration’s plan to rewrite the regulation, also called Waters of the United States. The contentious rule was scaled back by the Trump administration after being expanded under President Barack Obama.
Nearly $3.25 million in federal funding was preliminarily secured for separate project requests at the Salton Sea and the New River on Monday, July 12, according to the office of Congressman Juan Vargas, D-Chula Vista. The funding was part of a 2022 House Appropriations Energy and Water Subcommittee bill that included requests of $2.546 million for a major Salton Sea research project, $200,000 for a Salton Sea feasibility study, and $500,000 for planning and design phases for a potential New River restoration project, Vargas’ press release states.
On July 8, Gov. Gavin Newsom expanded two earlier drought emergency declarations to cover 50 of the state’s 58 counties. In May, he directed state agencies to consider easing requirements for reservoir releases to conserve water upstream, and to make water transfers easier. Both are needed.
Notably, the governor’s emergency proclamation did not impose water conservation mandates. Instead, Newsom is leaving water conservation to each region — a smart and necessary approach that incentivizes regional investments in water supply.
As California continues to face a drought brought on by record-breaking temperatures, Gov. Gavin Newsom is asking residents to reduce their water usage by 15%. However, this request does not apply to San Diego County.
Sandra Kerl, General Manager at the San Diego County Water Authority, joined KUSI’s Logan Byrnes on Good Evening San Diego to discuss what “America’s Finest City” is doing right.
Kerl explained that due to a “portfolio” of different water supplies and long-term conservation efforts, the city has enough water supply for now, despite the state’s drought.

Emergency conservation orders address short-term water shortages, but don’t move us toward the long-term goal of drought resilience. That requires strategic investments in local drought-resilient water supply projects, costs mostly borne at the local level.
The state recently took a step in the right direction by approving $3.5 billion in budgeted funds for water projects, but the details of how that money will be used are still being worked out. It is important that funds are directed to local drought-resilience projects. That would go a long way toward accelerating the 21st-century water solutions we need.
Consider our two regions: Sacramento and San Diego. We both have dry summers, but our water supplies are very different.
San Diego’s water comes from locally developed and imported water sources. Sacramento’s supplies come from nearby rivers fed by snowmelt and groundwater. That’s why we’ve chosen to solve our water supply challenges very differently.
Had the formidable white arc of the Hoover Dam never held back the Colorado River, the US west would probably have no Los Angeles or Las Vegas as we know them today. No sprawling food bowl of wheat, alfalfa and corn. No dreams of relocating to live in a tamed desert. The river, and dam, made the west; now the climate crisis threatens to break it.
The situation here is emblematic of a planet slowly, inexorably overheating. And the catastrophic consequences of the extreme weather this brings.
Earlier this year, GreenGenStorage received a renewal of their licensing period to submit Pre-Application Documents to the Federal Energy Regulatory Commission for their proposed Mokelumne Pumped Storage Water Battery Project. The developer hopes to submit their PAD by the end of the year for the project, which would utilize excess solar and wind energy to power their pumped storage technology, thereby generating electricity for the grid at peak energy-usage hours.
“During the midday peak of solar energy generation, we would pump water uphill to an upper reservoir,” Nicholas Sher, manager at GreenGenStorage said. “Then in the evening where energy usage is consumed the most, we would release that water downstream and it would drive a turbine, thus generating energy. Then by soaking up wind power in the evenings for release in the morning peak hours, we’re essentially just time-shifting renewable energy.”
By using renewable energy to transfer water back and forth between two reservoirs, the project would be a non-consumptive means of using water to generate power. In the case of the Mokelumne Pumped Storage Water Battery Project, the Salt Springs Reservoir has been identified as the lower reservoir, as it already has a small hydro-facility on it that generates about 44 megawatts of energy.
Two options are currently being explored for the upper reservoir that Salt Springs would be connected to via penstock pipes: the Lower Bear or Upper Bear Reservoir.
