Federal approvals clear way for Klamath River dam removals

January 18, 2023 — A decades-long effort to remove four dams on the lower Klamath River in California and Oregon would be the largest dam removal in the world. The dam removals would reopen access to more than 400 miles of habitat for threatened coho salmon, Chinook salmon, steelhead trout, and other threatened native fish.

The Federal Energy Regulatory Commission on Nov. 17 gave final approval for the surrender of utility licensing for the dams, clearing the way for their removal as part of the restoration effort.

NOAA is one of many partners collaborating to build a network of restored habitat that can support these species once the dams are removed. NOAA, the Pacific States Marine Fisheries Commission, and Trout Unlimited have released a detailed plan for restoring habitat in a key portion of the watershed.

Farms, fish on dry California-Oregon border see scant water

April 12, 2022 — Farms that rely on irrigation from a depleted, federally managed lake on the California-Oregon border, along with a Native American tribe fighting to protect fragile salmon, will both receive extremely limited amounts of water this summer as a historic drought and record-low reservoir levels drag on in the U.S. West.

More than 1,000 farmers and ranchers who draw water from a 257-mile-long (407-kilometer) river that flows from the Upper Klamath Lake to the Pacific Ocean will have access to roughly one-seventh the amount they could get in a wetter year, a federal agency announced Monday. Downstream salmon will receive about half the water they’d get if the reservoir was full.

It’s the third year in a row that severe drought has impacted farmers, fish and tribes in a region where there’s not enough water to satisfy competing demands. Last year, no water at all flowed through the Klamath Reclamation Project’s main irrigation canal, and thousands of downstream juvenile salmon died without reservoir releases to support the Klamath River’s health.

Shasta River Habitat Restoration Builds Salmon’s Resilience to Rising Temperatures

July 28, 2021 — The following was released by NOAA Fisheries:

Many species, such as salmon, rely on cool waters to survive during the hot summer months. But with temperatures rising due to climate change, these cold-water habitats are being threatened. In California’s Shasta River, a NOAA-supported habitat restoration project is helping to keep waters cool for salmon.

The Shasta River is an important tributary of the Klamath River, which was once the third largest salmon-producing river on the West Coast. Historically, the Shasta River supported more than 80,000 salmon each year. Today, however, only up to a few thousand adult salmon return to the river each year.

One of the issues facing Chinook salmon, steelhead trout, and threatened coho salmon in the Shasta River is a lack of healthy habitat. In particular, high water temperatures and poor water quality during the hot summer months can lead to lethal conditions for salmon.

Juvenile salmon need access to cool water to survive warm summer temperatures. In healthy habitats, trees and other vegetation growing along the banks of rivers and streams provide shade that keeps the water cool. Deep, fast-moving waterways also stay cooler than shallow, slower-moving ones. As water temperatures continue to rise due to climate change, maintaining these cold-water habitats for salmon becomes more crucial.

On Big Springs Creek, a tributary to the Shasta River, water temperatures were heating up as high as 77 degrees Fahrenheit—too warm for salmon to tolerate. These high temperatures were caused in part by uncontrolled livestock grazing. Cows were eating the vegetation that otherwise would have provided shade and kept the water cool. They were also trampling the streambed, creating a shallower, wider river channel that was more easily heated by the sun’s rays.

Warming rivers in U.S. West killing fish, imperiling industry

July 27, 2021 — Baby salmon are dying by the thousands in one California river, and an entire run of endangered salmon could be wiped out in another. Fishermen who make their living off adult salmon, once they enter the Pacific Ocean, are sounding the alarm as blistering heat waves and extended drought in the U.S. West raise water temperatures and imperil fish from Idaho to California.

Hundreds of thousands of young salmon are dying in Northern California’s Klamath River as low water levels brought about by drought allow a parasite to thrive, devastating a Native American tribe whose diet and traditions are tied to the fish. And wildlife officials said the Sacramento River is facing a “near-complete loss” of young Chinook salmon due to abnormally warm water.

A crash in one year’s class of young salmon can have lasting effects on the total population and shorten or stop the fishing season, a growing concern as climate change continues to make the West hotter and drier. That could be devastating to the commercial salmon fishing industry, which in California alone is worth $1.4 billion.

The plummeting catch already has led to skyrocketing retail prices for salmon, hurting customers who say they can no longer afford the $35 per pound of fish, said Mike Hudson, who has spent the last 25 years catching and selling salmon at farmers markets in Berkeley.

CALIFORNIA: CDFW Successfully Relocates 1.1 Million Hatchery Salmon Until Klamath River Drought Conditions Improve

July 15, 2021 — The following was released by the California Department of Fish and Wildlife:

Due to drought and poor water conditions in the Klamath River, the California Department of Fish and Wildlife (CDFW) successfully relocated 1.1 million juvenile, fall-run Chinook salmon from its Iron Gate Fish Hatchery in Siskiyou County. The fish were trucked to a nearby satellite facility and to the Trinity River Hatchery 122 miles away where the fish will remain until conditions in the Klamath River improve.

The baby salmon, about seven months old and about three inches in length, are normally released into the Klamath River in May and June. Due to warm water temperatures, low water flow and an exceedingly high probability of succumbing to disease in the river, CDFW decided to retain these salmon within its hatchery system over the summer until Klamath River conditions improve. The unprecedented relocation happened after extensive monitoring, discussion and close collaboration with federal partners, academic specialists and three Native American tribes in the lower Klamath Basin.

The temporary relocation marks the first time CDFW has not released salmon into the Klamath River since construction of the Iron Gate Fish Hatchery in 1962.

CDFW relocated the 1.1 million salmon to provide adequate water conditions over the summer and additional space to accommodate the growing fish. Another 1 million juvenile Chinook salmon will remain at Iron Gate.

“It’s extremely challenging to raise cold water fish species in a drought,” said Dr. Mark Clifford, Hatchery Environmental Scientist for CDFW’s Northern Region. “The reality is most of these fish would have died if we released them into the river. We need to maintain the integrity of the fall run on the Klamath River and we especially can’t afford to lose this generation of fish.”

Four Klamath River dams are slated for removal by 2024, the largest dam removal undertaking in U.S. history. The removal is expected to restore fish access to the entire river and the relocated Iron Gate fish could be the first salmon to return to a new Klamath River after their life in the ocean and find miles of additional spawning habitat and contribute to future generations of wild fish.

Salmon study sheds light on why fall-run fish are bigger than their spring-run cousins

October 30, 2020 — For the Yurok people, who have lived at the mouth of the Klamath River for generations, the spring run of Chinook salmon (Oncorhynchus tshawytscha) is a welcome—and nutritious—relief from winter. But as the fish have dwindled to just a fraction of their original numbers, Indigenous groups there are pushing to have them protected by the Endangered Species Act. New research, which suggests genes play only a small role in distinguishing the spring salmon from their fall-run cousins, may call into question the need for such a designation.

The rivers of the Pacific Northwest used to teem with two waves of Chinook: those that arrived in March or April, and those that came 6 months later, swimming from the sea to their upriver breeding grounds. Although technically the same species, the spring-run and fall-run fish have some “iconic differences,” says Eric Anderson, a molecular geneticist at the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center. Spring salmon are smaller, fattier, and less sexually mature than fall fish. They also swim further upriver to breed.

To tease out the genetic basis of those differences, Anderson and colleagues teamed up with Yurok fishers living at the mouth of the Klamath River in northern California. Together, they examined 500 fish as they started their upstream journeys in all four seasons. The researchers measured the size of each fish, assessed its fattiness and reproductive status, and took samples of its DNA. The researchers gathered similar data from other rivers.

Past studies have shown that a small region of the salmon chromosome 28 contains two genes, GREB1L and ROCK1, that vary between spring and fall salmon. Anderson and his colleagues did further genomic studies, sequencing the whole genomes of 160 fish in the hopes of linking the two genes to the spring and fall traits. The data set is “impressive” and the work unique says Sheela Phansalkar Turbek, an evolutionary biologist at the University of Colorado, Boulder, who was not involved with the work.

Can salmon eat their way out of climate change?

December 12, 2019 — Warm waters are a threat to cold water fish like salmon and trout. But a study led by researchers at University of California, Davis suggests that habitats with abundant food sources may help buffer the effects of increasing water temperature.

The study, published in the Canadian Journal of Fisheries and Aquatic Sciences today, Dec. 10, shows that the availability of food in a natural system—not just stream  and flows—is an essential component of  habitat.

“In the future under climate change, productive ecosystems like spring-fed rivers, floodplains, estuaries and seasonal lagoons will be key links that give  like  and trout a leg up,” said lead author Robert Lusardi, a research ecologist and adjunct faculty at UC Davis and the California Trout Coldwater Fish Scientist.

For the experiment, researchers reared juvenile Coho salmon in a series of enclosures within the Shasta River basin, which is a tributary to the Klamath River. They examined how natural gradients in temperature and prey availability affected summer growth rates and survival.

Pacific Council Finalizes Generally Improved Salmon Seasons for 2019

April 17, 2019 — Most salmon trollers can expect better ocean salmon seasons this year — while also meeting conservation goals, fishery managers said Monday.

The Pacific Fishery Management Council finalized its recommendations for 2019 salmon seasons at its meeting in Rohnert Park, Calif., for seasons beginning in May.

The seasons must still be approved by the U.S. Secretary of Commerce, but managers said that is expected.

The adopted regulations for Chinook salmon reflect the improved status of Sacramento River fall Chinook, Oregon managers said in a notice to industry. Rogue River fall Chinook and Klamath River fall Chinook populations both are in good and fair condition, respectively, they added.

Also, most of the north migrating stocks of Chinook (Oregon Coastal Chinook stocks from the Nehalem River south to the Elk River as well as a number of Columbia River Chinook stocks) are in moderate to poor condition. These north migrating stocks of Chinook contribute very little to Oregon’s ocean seasons but are very important to Oregon’s inside estuary and river recreational seasons.

The commercial ocean troll salmon seasons north of Cape Falcon will have very limited Chinook salmon quotas again this year. The ocean fishery will be managed by quotas, season length, and vessel landing week (Thursday-Wednesday) limits. The early Chinook salmon-only season will start on May 6. The season will continue until the overall quota of 13,200 Chinook or the Leadbetter Pt., Washington, to Cape Falcon (in northern Oregon) subarea cap of 1,800 Chinook is taken, or June 28, whichever comes first. Fishermen will be limited to 100 Chinook per vessel for the period of May 6-15 and then shift to a 50 Chinook per vessel per landing week (Thursday-Wednesday), beginning May 16.

The summer all-salmon fishery north of Cape Falcon will open on July 1 and continue through the earlier of the overall Chinook quota of 13,050 Chinook or 30,400 fin clipped coho, managers said in the notice to fishermen. Trollers will also be limited to 150 adipose fin-clipped coho during the landing week (Thurs-Wed) per vessel.

This year’s fisheries were designed to take advantage of a higher number of coho salmon forecast to return to Washington’s waters as compared to recent years, Kyle Adicks, salmon policy lead for the Washington Department of Fish and Wildlife, said in a press release. However, projected low returns of key Chinook stocks in Puget Sound prompted fishery managers to restrict fisheries there.

“We’re able to provide more opportunities to fish for coho in some areas, particularly in the ocean and Columbia River, than we have been able to do for several years,” Adicks said. Coho fisheries generally benefit sport fishermen but can constrain commercial fishermen targeting Chinook if coho is taken incidentally. “But continued poor returns of some Chinook stocks forced us to make difficult decisions for fisheries in Puget Sound this year.”

Again in 2019, fishery managers projected another low return of Stillaguamish, Nooksack and mid-Hood Canal Chinook and took steps to protect those stocks.

WDFW Director Kelly Susewind acknowledged the reductions in Puget Sound salmon fisheries are difficult for both fishermen, primarily sport fishermen, and the local communities that depend on those fisheries.

“Reducing fisheries is not a long-term solution to the declining number of Chinook salmon,” Susewind said. “The department will continue working with the co-managers, our constituents, and others to address habitat loss. Without improved habitat, our chinook populations will likely continue to decline.”

Limiting fisheries to meet conservation objectives for wild salmon indirectly benefits southern resident killer whales. The fishery adjustments will aid in minimizing boat presence and noise, and decrease competition for Chinook and other salmon in these areas critical to the declining whales, WDFW said in a press release.

In the rest of Oregon, from Cape Falcon to Humbug Mountain near Port Orford in southern Oregon, the Chinook salmon season will be open April 20-30, May 6-30, June 1-Aug. 29, and Sept. 1 through Oct. 31. Beginning Sept. 1, a 75 Chinook salmon per vessel weekly limit (Thursday through Wednesday) will be in place.

From Humbug Mt. to the Oregon/California border, the commercial troll fishery will be open April 20-30 and May 6-30. Beginning June 1, landing week (Thurs-Wed) limits of 50 Chinook per vessel will go into effect along with monthly quotas of 3,200 Chinook in June; 2,500 in July; and 1,200 in August (8/1-29).

“I really appreciate everybody’s work this week,” Oregon Department of Fish and Wildlife Fish Division Deputy Administrator Chris Kern said on the Council floor. “[It was] a lot of hard work, but I feel pretty good about where we landed.”

Similarly, California trollers should expect more time on the water this year.

Brett Kormos, with the Marine Region of the California Department of Fish and Wildlife, noted the two primary rivers, Sacramento and Klamath River, that contribute fall Chinook to ocean salmon fisheries are still in a rebuilding phase or overfished status. Still, “we are also looking at increased harvest opportunities in both commercial and recreational sectors in 2019 compared to 2018,” Kormos said.

Fishery managers modeled the seasons and limits to allow for a Sacramento River fall Chinook spawning escapement of 160,129 hatchery and natural area adults.

Oregon, California senators step up pressure on Trump administration to approve salmon emergency cash

October 5, 2017 — Oregon and California’s four senators, all Democrats, stepped up the pressure on the Trump administration Wednesday to approve disaster assistance for salmon fishermen along 200 miles of coastline.

In April, the Pacific Fishery Management Council, which manages coastal salmon seasons, recommended closing coastal and commercial salmon fishing entirely along an area equal to roughly half of Oregon’s coastline. Govs. Kate Brown of Oregon and Jerry Brown of California requested emergency funding relief in May, to no avail.

The fall chinook fun on the Klamath is the biggest and is important for recreational and tribal fisherman as well as commercial fisheries. The Yurok tribe, which has preference along the waterway, also had its allocation severely curtailed this year, to roughly 650 fish. Management officials estimated returning salmon to be roughly 12,000.

Oregon has had success in securing emergency assistance for salmon fishery disasters under both Republican and Democratic administrations. Emergency funds were approved in 2006, 2008, 2009 and 2010.

Oregon Sens. Ron Wyden and Jeff Merkley, and their California counterparts, Sens. Diane Feinstein and Kamala Harris, sent a letter Wednesday to the National Oceanic and Atmospheric Administration’s fisheries division urging action before the end of 2017.

California, Oregon governors request salmon disaster declaration

May 26, 2017 — California Gov. Jerry Brown and Oregon Gov. Kate Brown called on the U.S. Secretary of Commerce Wilbur Ross on Thursday to declare a federal fisheries disaster due to this year’s unprecedented low number of ocean salmon, according to the California Department of Fish and Wildlife.

The disaster declaration would allow Congress to appropriate relief funds to aid losses sustained by the salmon fishing fleet in California and Oregon. North Coast representatives including state Sen. Mike McGuire (D-Healdsburg), Assemblyman Jim Wood (D-Healdsburg) and 2nd District Congressman Jared Huffman (D-San Rafael) had asked Jerry Brown to request a disaster declaration earlier this year after the Pacific Fishery Management Council recommended restricting salmon fishing off the coasts of California and Oregon.

Ocean salmon fishing for Klamath River salmon is completely closed this year after the council predicted the lowest return of spawning Chinook salmon on record at about 12,000 fish.

Tribes, fishing organizations and North Coast representatives praised the governors’ requests on Thursday.
