Celebrate the San Joaquin River restoration project!

 Despite the snarky headline some editor threw over the excellent Fresno Bee article on saolmon restoration on the San Joaquin River, Lewis Griswold's story is full of the current scientific information on the project and optimism. Michael Fitzgerald, longtime Stockton Record columnist, celebrates the restoration project 125 miles south of Stockton and shows how fresh water crossing the valley from Friant Dam to the Mendota Pool will freshen the river as it passes by  Stockton.
Celebrate the restroration of this section of the San Joaquin River, selected by American Rivers group in 2016 as the second most endangered river in America and the most endangered in 2014. As you will see below, the restoration project took years of legal struggle and continues to face congressional opposition from south Valley Republicans, despite the support from the farmers' and towns' water districts directly affected. -- blj

San Joaquin River salmon make big gains, but don’t call it a comeback yet
By Lewis Griswold
Fish biologists bringing back salmon runs on the San Joaquin River say a record number of fish nests have been found in the river below Friant Dam east of Fresno.

The number of nests, called redds, created by spring-run Chinook salmon reached 41 this year, compared to just 13 last year.
“It’s a vast improvement over previous years,” said fish biologist Don Portz, manager of the San Joaquin River Restoration Program. “That’s triple the amount.”
The numbers are encouraging to fish scientists because they show the restoration program is making progress in re-establishing a wild salmon fishery on the San Joaquin after six decades of absence. But there’s a lot of work to do before scientists can say they’ve done all they can.
 “Right now we’re in the infancy stages of bringing the fish back,” Portz said.
Last year, for the first time in 60 years, spring-run Chinook salmon successfully reproduced in the river, which made headlines.
To monitor the fish after they hatch, biologists are installing special nets, called emergence traps, directly on top of nine redds. The nets are designed to catch, but not kill, emerging salmon fry.
So far this year, no salmon fry have been found, but it’s early yet. It takes a couple of weeks for fish to hatch and a lot depends on water temperature. But when they appear, experts will count them, weigh them, measure them and test for genetics.
“I think it’s incredibly rewarding work to see how the fish are actually thriving in the sections of the river we are working on,” said fish biologist Stephanie Durkacz, who donned waders and installed several traps over the past two weeks. “There haven’t been spring-run chinook salmon spawning here in 60 years. ... It feels very historic.”
Turning the ‘spigot’ back on
The work is being done because an agreement with environmentalists requires the federal government to restore the lost salmon runs. A long stretch of the San Joaquin River dried up and with it the salmon when Friant Dam was built in the 1940s.
Several fish biologists, lawyers and members of the public recently toured the river with the Water Education Foundation, based in Sacramento. Portz, the river restoration program manager for the Bureau of Reclamation, laid out the stakes.
“This is a river that didn’t have flows for over half a century,” Portz said. “It’s not an easy thing to turn on the spigot and let water start flowing again.”
But hatchery-raised adult salmon released into the San Joaquin River are making redds and spawning, giving fish scientists hope for success.
A major goal of the restoration program is for salmon eggs laid naturally in the river to hatch and for juvenile salmon to swim to the ocean, reach sexual maturity, then return as adult salmon to spawn and die — and for the cycle to start all over again as it did for time immemorial.

That’s how it was until Friant Dam blocked the river in 1948 and the water stored in Millerton Lake was diverted to farms on the Valley’s east side as part of the federal Central Valley Project.
But under California fish and game code, dams must release enough water to keep fish alive downstream.
In 1988, the Natural Resources Defense Council sued the U.S. Bureau of Reclamation, which controls the dam, and all of the irrigation districts that use the water for farming. A federal judge sided with the NRDC.

At the judge’s urging, the parties in 2006 hammered out the San Joaquin River settlementmandating that both spring and fall salmon runs be restored, from Friant Dam to the confluence of the Merced River a distance of 153 miles.
Seeking a self-sustaining salmon population
There are two kinds of salmon in the San Joaquin River — fall run and spring run salmon.
Spring run salmon evolved to take advantage of spring pulses of snowmelt rushing down from the Sierra Nevada. Historically, the fish swam up from the ocean and lived in deep pools of cool water during the summer, then spawned in the fall.

By contrast, fall run salmon arrived in late November to early December and quickly spawned. Both spring run and fall run juveniles swim to the ocean in the late winter and spring.
“If you can’t bring them both back, we’re supposed to focus on the spring run,” Portz said.
The fish that hatched in the river late last year are spring run salmon. It was considered a major milestone.

The work has been slow to ramp up, but Portz says they’ll have all the necessary work completed by the end of 2024 so both spring and fall run salmon can swim unimpeded from the ocean to Friant Dam.
The Natural Resources Defense Council is keeping a close watch on developments.

“Progress is slower than required, and that is disappointing,” said NRDC lawyer Doug Obegi in an interview with The Bee. Still, he said, “we should have a fully functioning river, and that’s encouraging ”
The effort is funded by state and federal governments. Eastside farmers pay a “Friant surcharge” for their irrigation water, and the collected funds, about $8 million a year on average, is paid to the federal government.

Portz said the original cost estimate for the restoration work was $1.5 billion to $1.6 billion, but program managers gave the budget a “haircut” to cut costs. “It still came to $648 million for just phase one,” he said.

Costs include a new fish hatchery near Friant Dam, which is behind schedule but should open next year. The hatchery will eventually produce 1 million salmon fingerlings annually. An interim hatchery on the river now produces 200,000 fish per year.

The hatchery is needed because naturally producing salmon on the river won’t be enough to restore the salmon runs, at least at first.
“We want a naturally reproducing, self-sustaining population, but you need a supplement,” Portz said.

The long-term goal is to have tens of thousands of returning salmon — 10,000 fall run and 30,000 spring run.
This year, 168,000 juvenile hatchery fish were released into the river and last year it was about 150,000. Similar numbers have been released since 2014. It takes two or three years for them to return as adults.
What’s the next milestone?
So far, returning adult Chinook salmon have not yet been seen in the San Joaquin River. But Portz and the other scientists have their fingers crossed that salmon will start showing up on the San Joaquin next spring.
When that happens, “the returning adult spring run salmon will be the next milestone for the program,” he said.
Because of physical barriers still in the river that stop the migrating fish, the fish will be netted downstream and trucked to the waters below Friant Dam, he said.

There currently isn’t enough water in the river to support a fully functioning salmon fishery, Portz said. Levees will be built where needed so the channel can contain more water, he said.
There’s also a need to build “fish passages,” man-made structures allowing fish to swim around dams and get upriver on their own, which biologists call “volitional passage.” The fish passages will be built by 2024 as required by the settlement, Portz said.
But it’s water temperature that is the crucial factor for salmon survival, he said, especially for juvenile fish going out to the ocean. That’s why cool water at the bottom of Millerton Lake must be sent downriver.
“We have to time our releases effectively,” Portz said. “We need to have planned pulses to move the juvenile fish and start their migration to the ocean.”
The settlement requires water in the river all year long. That leaves less irrigation water for farmers — about 15 percent to 20 percent less per year on average than before the settlement.
But the farmers are banking on there being no more reductions and support bringing back salmon on the river.
“Friant Water Authority continues to be invested in the long-term success of the San Joaquin River Restoration Settlement and program,” the water delivery agency said in a statement. “We believe the terms of the settlement were fair and we’re working with our partners to fully implement it.”
One major unknown, meanwhile, is the effect of climate change on the San Joaquin River salmon. Spring run salmon would probably do better than fall run salmon in an era of global warming, Portz said.

“Because they spawn earlier in the fall, they move out earlier in the year: February, March, into April,” he said. “Water temperatures are still cool.”
But it means managers must make the right calls so the adult salmon will return despite climate change, he said.
“People are going to say, ‘This can’t be done,’ ” Portz said. “But if we do our fish passage right, and provide the habitat that’s necessary, I think it is attainable.”
Other work includes creating rearing habitat for salmon, adding screens to keep fish from migrating into side channels where they would get stranded, and building a fish screen, to be the largest in the state, to keep salmon out of Mendota Pool on the Valley floor.

Additionally, more gravel must be put in the river so returning adult fish can create their redds.



Stockton Record
Fitzgerald: A ‘birth announcement’ on the San Joaquin River

By Michael Fitzgerald 
Record columnist 
As long as salmon swim our rivers, The Age of Miracles is not over. So it is heartening to hear that salmon reproduced in the San Joaquin River for the first time in 60 years.
Biologists restoring the San Joaquin took eggs from Northern California streams to a hatchery, raised ’em, released 115 adults and voila: 405 juvenile spring-run salmon counted, so far.
“It is a really encouraging sign,” said Doug Obegi, a senior attorney with the Natural Resources Defense Council.
The one-off success is not conclusive — more testing is required — but, Obegi said, “This is a bit of good news, and in 2018 I will take that wherever I can find it.”
Right. The NRDC had to sue for 18 years to restore the river’s fish and wildlife, which were clobbered in 1942 when Friant Dam north of Fresno diverted every drop of water.
Before Friant, the San Joaquin was one of California’s great rivers. After Friant, 62 miles of river dried and died. Salmon were thwarted.
The water grab robbed Stocktonians (and countless others) of their birthright to a healthy river.
The water passing Stockton, by the way, is largely recirculated farm water runoff laden with fertilizer, pesticide and cooties. A sort of liquid low expectation.
Its impact on the quality of city and Delta life — well, we can hardly conceive, until the river comes fully to life again. That day is one critical step closer now.
“I do think that it is coming, and it is very soon,” said Obegi.
Collecting eggs, biologists raised salmon in tanks to 3- and 4-year-old adults at the hatchery just downstream of Friant. They released them into the river.
Naysayers said the river was too far gone. Flows were too low, climate change had warmed the water too much. But the salmon build “redds” — nests — and spawned before dying.
For all I know, some of the juveniles are swimming past Stockton right now, heading for the sea.
Pause to appreciate a critter that can live in freshwater and salt water. One that used to cascade past Stockton in the millions “so thick that a person could walk across the stream on their backs.”
Such accounts may be exaggeration. But hardly. In 1873, Joaquin Miller wrote of the Sacramento River, “I have seen ... the stream so filled with salmon that it was impossible to force a horse across the current.”
When the lawsuit was settled, “restoration flows” to the San Joaquin began — in 2014-15 were curtailed during the drought — and in August of last year, water finally flowed across that 62-mile Sahara and reconnected the San Joaquin River from the mountains to the Pacific.
The salmon highway.
Though all parties signed the settlement, backward south-Valley Republicans and the special interests they represent have fought to sabotage the restoration every step of the way.
HR23 by Rep. David Valadao, R-Hanford, in the words of his website, “reforms onerous federal laws,” which “resulted in hundreds of billions of gallons of badly needed water being flushed into the ocean.”
Translation: the bill would re-dry the river by diverting every drop to corporate agri-business. Such a vision for the state’s second-largest river is the definition of the word “anachronism.”
And is wholly unnecessary. The settlement requires the restoration to “reduce or avoid cutting water supply to all of the Friant Division long-term contractors.” Those guys will be looked after, just not as much as the grabbiest among them desire.
Today, restoration flows remain low, only 100-150 cfs. Many salmon won’t make it past the Mendota pools and over the dam there. But later this year, flows will be ramped up.
The goal is to reach a healthy 2,500 cfs by 2024.
“We’ve seen in higher years when there are higher flows fish can make it out of the system,” Obegi said.
And back in, bringing wonder and tremendous nutrients to the web of life. Not to mention less turgid filth running past this city, as well as creating, unscientifically speaking, better mojo.
“I think we are all frustrated that the river restoration is not progressing as quickly as we wanted it to,” Obegi said . “But seeing salmon spawning successfully in the river by themselves really is a sign that we are turning the corner and bringing this river back to life.”
