Unpredictable snowpack, dwindling water supplies, collapsing fish populations, and an expected update to the Bay-Delta plan make CA water management issues more urgent than ever before.

"And there are folks who just don't care about those things. And I like to tell them these are just messengers of worse things to come," as our lead scientist @jarosenfield told ABC-7 News.

That's why we're taking action, along with our partners at the Center of Biological Diversity, to hold the Bureau of Reclamation accountable under the law.

Environmental groups sue to stop Trump's water diversions in California

Several Environmental groups, including San Francisco Baykeeper and the Center for Biological Diversity are now suing, claiming the Action 5 diversions violate the endangered species act and will harm fish populations including chinook salmon.

We just sued to challenge the Trump Administration's dangerous water grab—and its devastating effects on Central Valley Steelhead, Green Sturgeon & Chinook Salmon—in partnership with the Center for Biological Diversity and Friends of the River 🐟

The CA Department of Water Resources has fundamentally failed to show that the Delta Tunnel plan would create a reliable water supply while protecting & restoring the Delta ecosystem - and at the extraordinary cost of *over $20 billion*

State officials have a once-in-a-generation chance to save California salmon—and they're failing.

As our lead scientist @jarosenfield stresses in this article, the state's plan would drive native fishes to extinction:

"The voluntary agreements are an extinction plan," as our lead scientist
@jarosenfield describes the state's new Bay Delta Plan.

Endangered species will continue to plummet, more fisheries will shutter, and Tribes & Delta communities will continue to suffer with worse water quality.

California cities are paying a lot for water, while Ag is paying relatively little--and sometimes nothing at all!

California cities pay a lot for water; some agricultural districts get it for free

Water costs are confusing — even for the experts. A new study shows huge differences in what cities and farm water districts pay for supplies from rivers and reservoirs in California, Arizona, and Nevada.

"It's no secret that the Trump administration prioritizes handing out California's water to powerful water districts that support the administration," as Baykeeper science director @jarosenfield told the SF Chronicle. "This is part of the Trump administration's war on California and the Trump administration’s war on California's environment."

California opposes Trump administration plan to pump more delta water

The Trump administration plans to send more water to Central Valley farmlands. California is objecting, saying that poses multiple threats.

Los Angeles Times
From the Central Valley to SF/Berkeley, I’ve met inspiring academics & startup folks rethinking water & agriculture—plus survived my first @Waymo ride (impressed!).
The link between surface/groundwater and the infrastructure sustaining it is massive. California’s blend of tech, policy, and collaboration is an inspiring bundle for water management.
Now in Davis to dive deeper and grateful for the insights—excited to bring them back to Europe!
