Delta tunnel: MWD weighs moving intakes 20-30 miles north for sea level rise

Dierdre Des Jardins, CALIFORNIA WATER RESEARCH

On Wednesday, August 28, 2019, the Sacramento Press Club hosted a panel discussion, “Droughts, tunnels & clean water.” The panel included Wade Crowfoot, Secretary of Natural Resources, Jeffrey Kightlinger, general manager and CEO of Metropolitan Water District, and Jennifer Pierre, general manager of the State Water Contractors. Stuart Leavenworth from the LA Times moderated the panel.

The Newsom administration has committed to modernizing Delta Conveyance to protect water supplies from earthquakes and sea level rise. In a July 8 update to the Metropolitan Water District’s Water Planning and Stewardship Committee, Crowfoot stated, “if you are a state agency and you are building infrastructure that you want to exist and be operating in 2100, you need to plan for between 5 and 10 feet of sea level rise.” Crowfoot emphasized that sea level rise was one of the reasons the Newsom administration supported the Delta tunnel, stating, “when we’re talking about really protecting our water supply against sea level rise and saltwater intrusion, the underground conveyance or the tunnel becomes quite important.”

The Newsom administration has relied on assertions by the Department of Water Resources that the North Delta is 15 feet above sea level. But as explained in California Water Research’s August 12 blog post, this assertion is misleading. In the North Delta, only the top of the Sacramento River levee is 15 feet above sea level. Elevations at Courtland and Hood range from -1 to 8 feet above sea level, and the bottom of the Sacramento River is over 20 feet below sea level. California Water Research has recommended that new modeling be done of the performance of the North Delta intakes with high sea level rise.

During the Q&A period at the Sacramento Press Club luncheon,Deirdre Des Jardins advised the attendees of these facts. She asked Kightlinger and Pierre if they would commit to modeling the performance of the North Delta intakes with 10 feet of sea level rise and widespread levee failure. In response, Kightlinger stated that MWD is looking at moving the Delta tunnel intakes 20-30 miles north to accommodate sea level rise. Kightlinger stated that MWD is evaluating the increased costs of a longer tunnel, versus the benefits of extending the lifetime of the project.

It is unclear what intake locations Kightlinger was referring to. But in 2010, the Department of Water Resources evaluated two sets of locations north of Freeport, which would resist salinity intrusion with 10+ feet of sea level rise. The first set includes two locations on the west bank of the Sacramento River in South Sacramento, the second set, two locations upstream of the American River confluence. A third set of alternative locations was downstream of the confluence with Steamboat Slough. (see below.) These would benefit salmon but have less resistance to salinity intrusion.

These alternative locations were considered and rejected in 2010, partly on the basis of modeling by Resource Management Associates (RMA) which was interpreted to show no impacts from salinity intrusion at any of the proposed intake locations. But as explained in California Water Research’s August 6 blog, the 2010 RMA modeling is obsolete and has major limitations. The 2010 RMA modeling assumed 55 inches of sea level rise, and no failure of North Delta levees. The California Ocean Protection Council’s current estimate of maximal sea level rise by 2100 is 10 feet or 120 inches. This is over twice the 2010 estimate.

As part of “assessment of efforts to modernize Delta Conveyance,” California Water Research has recommended that the Newsom administration document that the WaterFix intake locations need to be reassessed for performance with 10 feet of sea level rise and widespread levee failure.

California governor makes big change to giant Delta water project

Kathleen Ronayne, ASSOCIATED PRESS

California Gov. Gavin Newsom scrapped a $16 billion plan Thursday to build two giant water tunnels to reroute the state’s water system and instead directed state agencies to restart planning for a single tunnel.

The move came after $240 million has already been spent on the project championed by former Gov. Jerry Brown to divert water from the north to the state’s drier south.

Newsom had signaled the move in his February State of the State address. He made the change official when he asked state agencies to withdraw existing permit applications and start over.

“I do not support the twin tunnels. But we can build on the important work that’s already been done,” he has said.

Brown wanted to build two, 35-mile-long (55-kilometer-long) tunnels to divert water from the Sacramento River, the state’s largest river, to the San Francisco Bay Area, San Joaquin Valley and Southern California. Local water agencies were expected to foot the roughly $16 billion bill.

A single tunnel is expected to cost less, but officials haven’t yet set a price tag, said Erin Mellon, spokeswoman for the state Department of Water Resources. Nor has the state determined how much water would flow through a single tunnel.

The twin tunnels are out—Berkeley experts say that’s a good thing

Glen Martin, CALIFORNIA MAGAZINE

The extravagantly wet winter notwithstanding, California’s water woes are far from over. But recent moves suggest Governor Gavin Newsom is leading the state into a new era of water policy. Last month, he decided to scale back his predecessor’s decades-long effort, the Twin Tunnels, to deliver water from Northern to Southern California.

“Really, the idea that two massive tunnels would be built in the Delta was always—well, a pipe dream,” says Peter Gleick.

This massive project, known as the California WaterFix, was promoted by Jerry Brown as the solution to the state’s agricultural and urban water insecurity and environmental degradation in the Sacramento/San Joaquin Delta. Conceived as two 35-mile-long, 40-foot-diameter pipes buried under the Delta, the Twin Tunnels would’ve incorporated a great deal of concrete, steel, and machinery to move tremendous quantities of water southward. (Read more about Brown’s water plan here.)

Ultimately, though, it was a bridge—or tunnel—too far, even for Brown. And UC Berkeley water experts generally agree Newsom’s move away from the WaterFix is a pragmatic one.

“Jerry really wanted that legacy project, but he overplayed his hand,” says Richard Walker, a Berkeley professor emeritus of geography who has written extensively on state infrastructure, water, and agricultural issues. “The WaterFix was clearly a relic of the past. It doesn’t accord with either the will of the people of California or the actual way that state water management is moving.”

“Really, the idea that two massive tunnels would be built in the Delta was always—well, a pipe dream,” says Peter Gleick, a UC Berkeley alum and the president emeritus of the Pacific Institute, a water-oriented think tank. “It was always clear that you could get far better results spending much less money by exploring other avenues.”

And that’s exactly what experts anticipate Newsom will do. By scaling back Brown’s all-encompassing megaproject, he appears to be moving towards what analysts call a “portfolio” approach—or multiple, integrated programs, including one smaller tunnel.

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.

PCFFA leads suit against State Water Board to protect salmon in the Water Quality Control Plan

Pacific Coast Federation of Fishermen’s Associations, YUBANET.COM

On Friday, Jan. 25, 2019, a coalition of environmental, fishing, and Native American groups led by the Pacific Coast Federation of Fishermen’s Associations (PCFFA) filed suit against the State Water Resources Control Board (State Water Board).

Plaintiffs demand that the State Water Board use its own recommendations based on science and environmental law to enact a Water Quality Control Plan protects fish in the Stanislaus, Tuolumne, and Merced rivers and in the main stem San Joaquin River blow their confluence.

These three tributaries of the San Joaquin River have historically supported vibrant runs of tens of thousands of Chinook salmon annually. Diversions of their waters by municipal water agencies, including San Francisco, and local irrigation districts over the past five decades have severely impacted those salmon runs, pushing them to the brink of extinction. The Water Quality Control Plan approved last month codifies what has heretofore only been a tacit approval of such diversions by the State Water Board.

In 2009, the California State Legislature adopted the Delta Reform Act to compel the State Water Board to take prompt action to save historic salmon runs. In 2010, the Board adopted the recommendations of a staff report which determined that, to save this public trust fishery, the San Joaquin River’s flows should be increased to a minimum of 60% of their historic (“unimpaired”) flows during the critical migration period of February through June.

On Dec. 12, 2018, the Board adopted minimum flow standards of just 40% of unimpaired levels on average, rather than the 60% average that its scientists showed was required to restore salmon runs.

PCFFA Executive Director Noah Oppenheim called Friday’s lawsuit, “a long overdue wake-up call that the State Water Board must now do its job to prevent the imminent extinction of this irreplaceable fishery. For decades this regulatory process has been captured by water agencies with no compunctions about hastening the end of salmon fisheries. Today salmon fishermen and fishing communities are raising their voice.”

Joining the PCFFA in filing suit are the North Coast Rivers Alliance and the Winnemem Wintu Tribe. All three agree that unless historic flows are restored immediately, the survival of the Delta’s salmon fishery is in jeopardy. A copy of the verified petition and complaint is here.

Their lawsuit alleges that the State Water Board’s failure to restore adequate flows in these rivers violates the federal Clean Water Act and California’s Porter Cologne Water Quality Act—which require protection of historic fish runs—and also the Public Trust Doctrine, which forbids the Board from allowing excessive diversions of water needed for the survival of the Delta’s salmon.

“Unless the Board is ordered to comply with the law and these flows are restored at the scientifically recommended levels, California’s salmon will never recover and the fishing families that bring the ocean’s bounty to the public will continue to suffer unjustly,” said Oppenheim.

Op-Ed: Stop efforts to kill salmon and fishing jobs

John McManus, THE PRESS DEMOCRAT

Today, many Northern California commercial fishermen sit in harbors along our coast worrying about their bills and waiting for another disastrously shortened salmon season to begin. Many businesses that serve the normally robust sport salmon fishery also have suffered because of the delay. River fishing guides have lost half their season as well.

Salmon numbers are predicted to be down from the lingering effects of the last drought and the damaging water allocation decisions that put salmon fishing families last. Meanwhile, San Joaquin Valley congressmen are hard at work tilting the balance of water in California toward valley agricultural barons.

These House members are acting like this is their last, best chance for a huge water grab. There are four separate riders in House budget bills aimed at seizing more Northern water at the expense of salmon and fishing families. None are responding to a crisis in agriculture. The past decade has seen record harvests, revenue and employment for California agriculture.

For salmon, it’s another story. During the past decade, California salmon fishermen have seen the two worst crises in state history. Our fishery was shut down entirely in 2008 and 2009 following record siphoning of Bay-Delta water. The Golden Gate Salmon Association and other fishing groups are seeing a second crisis today as salmon try to fight their way back from the drought.

The Bay-Delta’s salmon runs are the most important south of the Columbia River and the backbone of a $1.4 billion salmon fishing industry that supports 23,000 jobs.

Forecast shows California salmon fishermen in for another year of sharp limits

Mary Callahan, THE PRESS DEMOCRAT

A third straight year of low king salmon runs is expected to deliver another blow to one of the North Coast’s most iconic and lucrative fisheries, wildlife managers indicated Thursday, as both regulators and fishermen faced the prospect of a federally mandated plan to reverse the trend and rebuild key stocks.

The grim news comes amid a dramatic, yearslong decline in the state’s commercial salmon landings, which are down 97 percent last year from their most recent peak, in 2013, when they hit 12.7 million pounds.

The full picture for commercial and sport seasons won’t be clear for several more weeks, but spawning projections show Sacramento River salmon — historically the largest source for the state’s ocean and freshwater harvests — have fallen so low that they’re now considered by regulators to be “overfished.”

Wildlife officials acknowledged that term minimizes the many factors that have led to this point, including shifting conditions in the ocean and years of low river flows during the drought, all of which have pummeled stocks.

Jerry Brown officially downsizes Delta tunnel plan. But can he sell one tunnel?

Dale Kasler, THE SACRAMENTO BEE

The troubled Delta tunnels project was officially downsized Wednesday, as Gov. Jerry Brown’s administration announced it would attempt to build a single tunnel in its effort to re-engineer California’s elaborate water-delivery system.

Unable to secure enough money from California’s water agencies for the original twin tunnels concept, the California Department of Water Resources said it would now try to build the project in phases: one tunnel now and a second tunnel years down the road.

The long-awaited announcement doesn’t appear to immediately solve the financial questions looming over the project, known officially as California WaterFix.

A letter to water agencies from DWR Director Karla Nemeth says the first tunnel would cost $10.7 billion. That’s much less than the price tag for building two tunnels, now officially pegged at $16.3 billion. But the one-tunnel option also is considerably more expensive than the estimated $6 billion to $6.5 billion that’s been pledged so far by participating south-of-Delta water agencies.

Op-Ed: The delta smelt heads for extinction, marking a half-century of failed California water policy

Michael Hiltzik, LOS ANGELES TIMES

The delta smelt is on the brink of extinction. This species…has fallen to the point where it can hardly be found anymore.— Doug Obegi, Natural Resources Defense Council

You might wish you had as much power to affect the environment and the economy as the delta smelt.
Enemies have blamed the tiny freshwater fish for putting farmers out of business across California’s breadbasket, forcing the fallowing of vast acres of arable land, creating double-digit unemployment in agricultural counties, even clouding the judgment of scientists and judges.
During the presidential campaign, the lowly smelt turned up in Donald Trump’s gunsights, when he repeated California farmers’ claim that the government was taking their water supply and “shoving it out to sea…to protect a certain kind of three-inch fish.”
But the delta smelt couldn’t be as powerful as all that. The latest California fish population survey in the Sacramento-San Joaquin Delta, which along with San Francisco Bay is the species’ only habitat, turned up only two delta smelt in four months of trawling from September through December. That’s the lowest count since 1967, and a far cry from the peak of 1,673 in 1970. The count is especially worrisome because it came after a wet year, when higher water flows in the delta should have led to some recovery in the numbers.
The figures arrive just as the Trump Administration is proposing to loosen Endangered Species Act protections for fish in order to “maximize water deliveries” to users south of the delta—that is, farmers—according to a Dec. 29 announcement by the Interior Dept. .

California water wars rage on as farmers seek more water that now goes to fish

Ryan Sabalow and Dale Kasler, THE SACRAMENTO BEE
The drought may be over and Central Valley farmers are getting more water than they have in years, but that hasn’t stopped congressional Republicans from resurrecting a bill that would strip environmental protections for fish so more water can be funneled to agriculture.
The bill is likely to meet the same fate as others before it, despite farmers having a new ally in the White House and Republican majorities in both houses of Congress. After passing the House of Representatives last week, the bill faces near-certain death in the Senate, where California Democrats Dianne Feinstein and Kamala Harris still have the power to kill it. President Donald Trump, who vowed during a Fresno campaign stop last year to “open up the water” for farmers at the expense of fish, is likely to never see the bill cross his desk.
Nonetheless, the legislation by Rep. David Valadao, R-Hanford, offers a window into the unrelenting mindset of California’s agricultural lobby as it seeks to secure water for well-funded farming groups.
Some version of Valadao’s bill has been introduced off and on since 2011 without success. And, last year, with Feinstein’s support, farmers succeeded in pushing through a controversial bill easing some of the environmental restrictions on pumping water through the Sacramento-San Joaquin Delta for delivery to San Joaquin Valley farms and Southern California cities. Former President Barack Obama signed the bill into law.
