California’s unnatural river flows threaten aquatic life—here’s a (partial) fix

“We always act surprised when drought shows up, with ad hoc actions to try to protect species and ecosystems,” Mount says. “One place to start is to give the environment a water budget and someone to manage it, especially during drought—we should plan for it, rather than react to it.”

As a New York Times columnist once quipped, “California’s water system might have been invented by a Soviet bureaucrat on an LSD trip.” The system was engineered in the 1900s to capture winter rain and spring snowmelt in vast reservoirs and then send this water to cities and farms via thousands of miles of canals, pipelines and tunnels.

While this system suits many people, it doesn’t suit fish, frogs and other river life. Many California waterways are regulated by reservoirs that release water for supply, flood control, and hydropower, resulting in river flows that are far from natural. Now there’s a movement to reinstate the seasonal flows that native species depend on.

“The idea of mimicking a natural flow regime is not rocket science and it’s not new,” says Sarah Yarnell, a river ecosystems expert at UC Davis. Like many innovations, it’s just taken a while to start percolating into the mainstream.

Critics rip ‘half-baked’ federal plan to save California salmon

Nick Cahill, COURTHOUSE NEWS SERVICE

Both conservationists and water suppliers are upset with a proposal that federal and state officials say is aimed at ensuring Chinook salmon survive the California drought.

Fishing groups and water suppliers fighting the Biden administration’s proposed drought rules for California’s water system told a federal judge Friday the emergency plans won’t stop the demise of endangered salmon.

With California trudging through another disappointingly dry winter, the federal government and state officials have agreed upon a set of temporary rules they claim are necessary to preserve enough cold water on the Sacramento River for Chinook salmon this spring and summer. The rules call for new water temperature targets and improved collaboration between federal and state officials on the management of California’s two main water conveyance systems.

But the Pacific Coast Federation of Fishermen’s Associations and other conservation groups cast the “interim operations plan” as a half-baked measure that will lead to a third consecutive year of salmon die-offs. They want the feds to hold off on upcoming water deliveries and subsequently store more cold water behind Shasta Dam in the event hydrological conditions remain dreadful.

In addition, a group of water agencies claim the interim plan was untested and, if implemented, would likely violate their contracts with the U.S. Bureau of Reclamation.

The overarching issue are endangered species permits or biological opinions adopted by the Trump administration in 2019 that critics said severely weakened protections for salmon and water quality in the Sacramento-San Joaquin River Delta.

Trump delivers on pledge for wealthy California farmers

Ellen Knickmeyer & Adam Beam, WSLS.com

Hoisting the spoils of victories in California’s hard-fought water wars, President Donald Trump is directing more of the state’s precious water to wealthy farmers and other agriculture interests when he visits their Republican Central Valley stronghold Wednesday.

Changes by the Trump administration are altering how federal authorities decide who gets water, and how much, in California, the U.S. state with the biggest population and economy and most lucrative farm output. Climate change promises to only worsen the state’s droughts and water shortages, raising the stakes.

Campaigning in the Central Valley farm hub of Fresno in 2016, Trump pledged then he’d be “opening up the water” for farmers. Candidate Trump denounced “insane” environmental rules meant to ensure that enough fresh water stayed in rivers and the San Francisco Bay to sustain more than a dozen endangered fish and other native species, which are struggling as agriculture and development diverts more water and land from wildlife.

Visiting Bakersfield in the Central Valley on Wednesday, Trump is expected to ceremoniously sign his administration’s reworking of those environmental rules. Environmental advocates and the state say the changes will allow federal authorities to pump more water from California’s wetter north southward to its biggest cities and farms.

The Trump administration, Republican lawmakers, and farm and water agencies say the changes will allow for more flexibility in water deliveries. In California’s heavily engineered water system, giant state and federal water projects made up of hundreds of miles of pipes, canals, pumps and dams, carry runoff from rain and Sierra Nevada snow melt from north to south — and serve as field of battle for lawsuits and regional political fights over competing demands for water.

Environmental groups say the changes will speed the disappearance of endangered winter-run salmon and other native fish, and make life tougher for whales and other creatures in the San Francisco Bay and Pacific Ocean.

After an initial study by federal scientists found the rule changes would harm salmon and whales, the Trump administration ordered a new round of review, California news organizations reported last year.
