Op-Ed: Mismanagement pushes salmon toward extinction

Tom Philp, PRESS DEMOCRAT

For California water managers, the Sierra snowpack has always been like money in the bank. With steady kisses of spring sun, snowmelt reliably flows ever downward until reaching the state’s vast network of reservoirs downstream.

But in the spring of 2021, in what turned out to be the second year of a scorching three-year drought, something happened to a meager snowpack. Much of it unexpectedly vanished into the sky or ground. Summer, as it now tends to do, had arrived early.

Faced with a cruel choice of who gets the limited water and who goes without, human decisions designated the remnants of California’s once-massive salmon population as the losers. The operators of the state’s largest reservoir, behind Shasta Dam, had already begun to honor contracts that guarantee farmers a lot of water, come drought or deluge. That meant less water in the Sacramento River to keep its inhabitants alive.

When adult salmon returned from the Pacific Ocean that winter, they swam upstream to below the dam where they would traditionally spawn. But the low flow in the river was lethally hot. Nearly all the salmon eggs failed to produce offspring.

The tragic loss of these salmon is one of too many examples of how California keeps harming an iconic fish species it is supposed to protect. A drought is a setback for salmon in the best of times. Here is how the last one could not have been worse, thanks to human mistakes.

Op-Ed: Here is the first step to a sustainable water policy

Carolee Krieger, CALMATTERS

We do not have a water crisis. We have a water management crisis, and we must revamp our water policy to reflect a drier future.

Water that is promised in a contract but can’t be delivered is called “paper water” – shorthand for water that does not exist except in legal documents.

During its mid-20th century frenzy of dam and canal construction, California allocated much more water than it actually had. These paper water commitments far exceed the amount of water than is available in our reservoirs and rivers. According to a study from the University of California, Davis, “appropriative water rights filed for consumptive uses are approximately five times greater than estimated surface water withdrawals.”

What this restrained academic language reveals is a management crisis: no matter how much it rains and snows in California, we will always have a chronic water shortage because of overallocation.

Why is this happening? As the UC Davis study found, the state has promised five times more water than could ever be delivered. Accelerating climate change only compounds the problem: Virtually all reputable computer models confirm California will receive less snow in coming decades, meaning our water deficit will only grow.

Meanwhile, overallocation remains at the core of California Department of Water Resources policy. In 2021, the State Water Project could deliver only 5% of its contracted water.

Lawsuit challenges California’s failure to address State Water Project’s threat to Bay Delta, salmon runs

Center for Biological Diversity, MAVEN’S NOTEBOOK

Four environmental groups sued the California Department of Water Resources today over its approval of the long-term operation of the State Water Project, the massive system of dams, pumps and aqueducts responsible for siphoning water from Northern California to Southern California. The project approval also failed to analyze the environmental harms of building a new diversion tunnel to send water south.

Today’s lawsuit, brought by the Sierra Club, Center for Biological Diversity, Restore the Delta, and Planning and Conservation League, challenges the agency’s implausible conclusion that the project, which starves the San Francisco Bay-Delta of freshwater flows and has devastated most of the Delta’s native fish populations, will have no environmental consequences.

“It’s time for the state to be honest about the damage being done to the Delta ecosystem and our native fish by the unsustainable water diversions of the State Water Project,” said Jeff Miller, a senior conservation advocate at the Center for Biological Diversity. “We need increased freshwater flows to restore the Delta. The Department of Water Resources can’t pretend that diverting even more water under this project would be benign.”

Just weeks before the department approved the long-term operation of the State Water Project, it announced that it was pursuing the “One-Tunnel Delta Conveyance Project,” the latest version of the enormous tunnel that could increase the siphoning of Delta water. Although the tunnel would be part of the State Water Project, the department failed to consider the tunnel and its effects from water diversion in its environmental review.

“It’s bad enough that the department thinks the State Water Project has no environmental consequences,” said Kathryn Phillips, director of Sierra Club California. “But it’s completely absurd for the agency to separate the long-term operation of the State Water Project from the tunnel project, which it’s actively promoting as part of that long-term operation.”

In 2019 Gov. Gavin Newsom announced that he was abandoning the California WaterFix project, which would have created two 35-mile long, 40-foot wide tunnels to carry water south without passing through the Delta and nourishing its ecosystems. The Department of Water Resources has subsequently pursued a single tunnel project, but the smaller project still threatens further damage to salmon and other fish runs and the health of the Delta.

“Salmon, Delta smelt, farmers and towns all depend on the continued flow of fresh water into the Delta,” said Barbara Barrigan-Parrilla with Restore the Delta. “The state’s long-term plan for running the State Water Project just hides its determination to close the spigot.”

Op-Ed: Newsom is being played by Big Ag on Delta water

Editorial Board, SAN JOSE MERCURY NEWS

Governor must use best available science to protect California’s fresh water supply

He won’t admit it, but Gavin Newsom is being played by Big Ag interests as he tries fruitlessly to negotiate a truce in California’s water wars.

The governor’s apparent willingness to play into the hands of monied, agri-business players at the expense of the health of the Sacramento-San Joaquin River Delta remains the biggest mystery of his short tenure. It also threatens to trash his reputation as a strong protector of California’s environment.

The Delta supplies water for 25 million Californians, including about one-third of Bay Area residents. Scientists agree that allowing more, not less, water to flow through the Delta and west toward San Francisco Bay is essential for protecting fish life and providing a clean supply of drinking water for current and future generations. That means restricting pumping of water out the south end of the Delta into Central Valley farmland.

The governor has been trying for months to get the major urban and ag players to reach a voluntary agreement on water flows from the Delta. His stated goal has been to avoid the lengthy lawsuits that follow a state mandate. But on Dec. 10, the Fresno-based Westlands Water District, the largest agricultural district in the nation, threatened to pull out of the talks. Westlands General Manager Tom Birmingham said “it would be impossible to reach a voluntary agreement” if Newsom followed through on his November pledge to sue the Trump administration over the federal government’s plan to pump more water south to Central Valley farmers.

It’s the same strategy Westlands used in September to pressure the governor to veto SB 1. The bill would have established as state standards the federal environmental protections that existed before Trump became president.

SB 1 offered Newsom the tool needed to thwart the Trump administration. It might have also given the governor leverage to bring environmentalists and farming interests to the table to reach a voluntary agreement on Delta water flows. But the governor caved to Big Ag interests in hopes that they would work cooperatively on a negotiated deal. We see how well that strategy worked.

The question now is whether Newsom will capitulate again to agriculture interests by backing down on his promise of a lawsuit to block the federal government’s planned increase of Delta water diversions.

The governor has repeatedly made clear that he “will rely on the best available science to protect our environment.” That science is unequivocal.

In the same week that Newsom vowed to sue the Trump administration, the state released a draft environmental impact report based on “a decade of science and a quantitative analysis of best-available data on flows, modeling, habitat and climate change impacts.” The report made clear that the operating rules proposed by the Trump administration “are not scientifically adequate and fall short of protecting species and the state’s interests.”

The scientists in charge of the drafting the federal government’s environmental impact plan said much the same. That is, until the Trump administration got wind of the conclusions and promptly replaced the scientists. In short order, a new report emerged saying pumping an additional 500,000 acre-feet (one acre foot of water is enough to supply two households for a year) to the Central Valley wouldn’t hurt the Delta’s health.

The ball is in Newsom’s court. The governor should follow through on his lawsuit against the Trump administration and act on the best available science to secure California’s fresh water supply.

Salmon lose diversity in managed rivers, reducing resilience to environmental change

NOAA Fisheries West Coast Region, EurekAlert!

The manipulation of rivers in California is jeopardizing the resilience of native Chinook salmon. It compresses their migration timing to the point that they crowd their habitats. They may miss the best window for entering the ocean and growing into adults, new research shows.

The good news is that even small steps to improve their access to habitat and restore natural flows could boost their survival.

The curtailment of high winter river flows by dams means that they no longer provide the cue for the smallest fish to begin their migration to the ocean. The loss of wetlands in the Sacramento-San Joaquin Delta leaves little of the refuge habitat they need to grow along the way. Meanwhile later-migrating fish suffer from rising summer temperatures that reduce their survival even though they migrate at a larger size.

Fish that begin their migration in mid-spring are the ones that survive best and dominate adult salmon returns to rivers such as the Stanislaus. These results were cited in a study published this week in Global Change Biology. Flow alteration and habitat loss have in effect homogenized the survival opportunities of salmon in this highly managed river system, researchers wrote.

That diminishes what is called the “portfolio effect,” where a diversity of salmon migration strategies help the fish cope with changing environmental conditions. This is similar to how diversified investments help buffer your financial portfolio against jolts in the stock market. Chinook salmon in California evolved diverse migration timing to handle the wide variation in climate, ocean, and river conditions in the Central Valley region. This is also important as climate change and rapidly changing, “whiplash weather” patterns further alter the picture.

“You never know what’s going to be a winning strategy in the future,” said Anna Sturrock of the University of California, Davis, and lead author of the research that also included scientists from several other agencies and universities. “Keeping options on the table is the best strategy, but that is not what we see happening.”

The research also found that the lower flows released from dams tend to reduce fish production. This is likely due to reduced access to floodplain habitats and lower food production in rivers.

Bay Area salmon advocates decry proposed delta water diversions

Bay City News Service, SFGATE.COM

Officials from a San Francisco-based group dedicated to preserving the region’s salmon habitat say a new federal plan to divert more water from the Sacramento-San Joaquin River Delta and San Francisco Bay would decimate the fish as well as jobs.

“This is a blatant water grab that threatened thousands of fishing jobs and families in California,” said Dick Pool, secretary of the Golden Gate Salmon Association.

Added GGSA Director Noah Oppenheim, “The Trump administration won’t be able to get away with killing off our salmon runs if the state refuses to cooperate.”

These comments come in response to Monday’s release by the U.S. Bureau of Reclamation of a “biological assessment” helping guide long-term operation of the Central Valley Project and the State Water Project, which operate separate but largely parallel canals in the Interstate Highway 5 corridor.

The Trump administration aims to make more water available to the agricultural producers in the central part of the state. The biological assessment is part of that overall plan. It isn’t known yet how much more water state farmers could get.

The GGSA calls the assessment’s assertions “a step towards abandoning federal rules governing the damaging effects of the giant state and federal water diverting pumps in the Delta.”

“We’ve seen what happens when water users are given free rein to divert Bay-Delta water,” said Mike Aughney, another GGSA director, who also published USAfishing.com. He said that before 2008, so many baby salmon were killed that the commercial salmon fishing season was cancelled the following year.

If the state opts to free up additional water to help preserve fisheries, that water would likely come from the State Water Project, which serves a mostly urban use base. The federal Central Valley Project largely provides water for ag producers.

The economic power of the salmon fishing industry, GGSA officials said, is approximately $1.4 billion annually, at current volumes. This includes everything from commercial and recreational fishing, fish processors, equipment manufacturers, the hospitality industry and businesses that support the fishing industry.

Why some western water agencies are writing 100-year water plans 

Jerry Redfern, NewsDeeply

The plan calls for increased water conservation through groundwater management (including recharging the aquifer beneath Albuquerque), surface-water management (including protecting current water rights and buying more in the future), watershed restoration, water recycling and reuse programs and stormwater capture and storage.

In February of this year, the largest water district in a state with little water enacted a plan that attempts to manage that increasingly fickle resource for 100 years.
The plan, Water: 2120, is the Albuquerque Bernalillo County Water Utility Authority (ABCWUA) in New Mexico’s blueprint to direct water procurement, protection and use for the next century.
“This really came out of eight to 10 of us sitting around in a room every Wednesday morning and talking this through,” said Katherine Yuhas, water resources manager at ABCWUA and one of the lead planners on the project.
It’s common for water agencies to develop plans looking 20 to 40 years ahead, or in some cases 50 to 60 years. And ABCWUA, of course, has had planning documents in the past, the last one looking 60 years out. But “this is the first one to take into account climate change,” Yuhas said, and “it’s the first one to look out 100 years.” Plus, it covers everything from watersheds to infrastructure to household use.
Other Western water groups are also working on long-range plans. Santa Fe is looking closely at Water: 2120. Next year, Austin Water plans to unveil Water Forward, which it calls, “a water plan for the next century.”
And in Arizona, the Office of Assured and Adequate Water Supply Program at the Department of Water Resources requires new developments in certain metropolitan areas to show they have physical and legal access to water for 100 years.
