California’s two primary salmon species, Coho and Chinook, have experienced significant declines from historical populations.
Of particular importance is the Chinook salmon because the species supports commercial fishing and related jobs and economic activities at fish hatcheries.
The decline in salmon numbers is attributed to a variety of manmade and natural factors including drought, habitat destruction, water diversions, migratory obstacles created by local, state and federal water projects, over-fishing, unfavorable ocean conditions, pollution and introduced predator species. Wetlands have also been drained and diked; dams have blocked salmon from reaching historic spawning grounds.
Years of declining populations represent a significant economic loss and have led to federally mandated salmon restoration plans that complicate water diversions and conveyance for agriculture and other uses.
Before dams were built on the upper Sacramento River, flood water regularly carried woody debris that was an important part of the aquatic habitat.
Deprived of this refuge, salmon in the lower parts of the upper Sacramento River have had a difficult time surviving and making it down the river and out to the ocean. Seeing this, a group of people, including water users, decided to lend a hand with an unprecedented pilot project that saw massive walnut tree trunks affixed to 12,000-pound boulders and deposited into the deepest part of the Sacramento River near Redding to provide shelter for young salmon and steelhead migrating downstream.
With one report saying the state is facing an unprecedented loss of fish species, a local group has won $158,000 to look at how water released from Kent Lake affects local coho salmon and steelhead trout. The Marin Municipal Water District — the agency that operates the Kent Lake reservoir — is under a 1995 state Water Resources Control Board order to release water periodically to aid federally endangered coho salmon and threatened steelhead trout.
Before dams were built on the upper Sacramento River, flood water regularly carried woody debris that was an important part of the aquatic habitat. Deprived of this refuge, salmon in the lower parts of the upper Sacramento River have had a difficult time surviving and making it down the river and out to the ocean.
A harrowing report released by the environmental nonprofit organization California Trout and the University of California Davis on Tuesday states that nearly 75 percent of the state’s 31 salmon, steelhead and trout species are likely to become extinct within the next century if current trends continue.
Researchers have issued a dire warning for California’s native trout and salmon: Three-quarters of them will be extinct in the next 100 years unless urgent action is taken. This bleak assessment came Tuesday from biologists at the UC Davis Center for Watershed Sciences and from California Trout, a nonprofit advocacy group.
The California Department of Fish and Wildlife has pulled the plug on plans to release a quarter-million hatchery-born Chinook salmon into Bodega Bay after several North Bay conservation groups demanded the agency first conduct a full environmental review.
The two bills written by [Congressman Jared] Huffman and [Congresswoman Jackie] Speier would provide nearly $22.5 million in relief funds to the Yurok Tribe to aid salmon fishing communities and salmon restoration and monitoring projects. The bills would also provide more than $117 million for California Dungeness crab and rock crab fishermen affected by the delayed 2015-16 season.
Then-Secretary of Commerce Penny Pritzker declared a fisheries disasters for nine West Coast fisheries in January, including for the 2015-16 crab season in California and the 2016 salmon season for the Yurok Tribe. California 2nd District Congressman Jared Huffman (D-San Rafael) was one of 17 members of Congress who drafted a bipartisan letter to congressional party leaders in early April urging that they include the disaster funds in the new spending bill.
For anyone who wants to get out on the Sacramento River and fish the section of water from Keswick Dam to Highway 44, time is running out. The California Fish and Game Commission on Wednesday approved permanently closing that section of the river to all fishing from the beginning of April to the end of July every year.
[California 2nd District Congressman Jared] Huffman and a bipartisan group of 16 other legislators are urging congressional appropriation committees to include fisheries disaster funding in the spending bill for fishing fleets in Alaska, Washington, Oregon and California, which includes the California crab fleet and the Yurok Tribe salmon fishing fleet.
The fall-run Chinook fishery on both the Klamath and Trinity rivers will be closed in 2017. On Thursday, the California Fish and Game Commission voted to close both rivers to the take of any size Chinook salmon after the fall seasons begin — Aug. 15 on the Klamath and Aug. 31 on the Trinity.
Native American communities are bracing for a public health crisis this year in California’s misty, rugged northwestern corner. In the Pacific Ocean off the mouth of the Klamath River, record-low numbers of fall-run adult Chinook salmon are ready to make their annual migration up the river and its primary tributary, the Trinity River, to spawn.
The top West Coast fishery council has recommended the full closure of the sport and commercial Chinook salmon fisheries near the Klamath River for the 2017-18 season. The Pacific Fishery Management Council’s recommendation Tuesday was expected after it forecast the lowest return of Klamath River Chinook salmon on record, with about 12,000 fish expected to return.
For the first time in its history, the Karuk Tribe will be limiting ceremonial salmon harvests for tribal members because of the record low forecast for returning Chinook salmon on the Klamath River. … The tribe’s announcement came as the Pacific Fishery Management Council met in Sacramento to discuss catch limitations for this year’s salmon season.
For the second year in a row, California officials are likely to shorten the chinook salmon season, making the local specialty costly and hard to find throughout the summer and possibly beyond. … The low numbers are due to lingering effects of the drought, because impacts on the population are felt about three or four years behind years with little rain.
California tribes and fishermen stated Thursday they will be calling on Gov. Jerry Brown to declare a fisheries disaster because of the dismal forecast for this year’s salmon season. … These statements came exactly a year after top state, federal and tribal officials gathered at the mouth of the Klamath River to sign a renewed agreement to remove four dams from the river.
A bipartisan group of congressional representatives sent a letter to House and Senate leaders Wednesday urging them to include disaster relief funds for nine West Coast crab and salmon fisheries in a government spending bill this month.

Both sport and commercial salmon fishing near the Klamath River could be completely closed this year as a result of what the Pacific Fishery Management Council is projecting to be the lowest return of spawning Chinook salmon on record.
About one million endangered fish flooded into a stretch of the Feather River near Yuba City Monday, transported out of the Thermalito annex of the Feather River Fish Hatchery by the California Department of Fish and Wildlife and National Oceanic and Atmospheric Administration National Marine Fisheries Service.
California’s chinook salmon — or some of them — are in trouble again. And under a set of proposed rules approved Monday, that’s likely to mean a very restricted salmon season for both commercial fishers and recreational anglers alike.
Crews worked Tuesday to clean up dirt and debris from the base of Oroville Dam and biologists rush to save stranded fish after state officials shut off the flow of water from a damaged spillway at the Northern California lake.
When California state biologists crested a sandbar along the Feather River on Tuesday morning, they expected to find at least some of the water that just a day before had raged through the channel, too deep to stand in – and plenty of fish needing to be rescued.
The federal government can redirect water from a Northern California dam to prevent mass die-offs of salmon in drought years, water that otherwise would be shipped to Central Valley farmers, a federal appeals court ruled Tuesday.
Days before nearly 200,000 people downstream of Lake Oroville were ordered to evacuate because of problems with two spillways at the dam, there were millions of other evacuees – residents of the Feather River Fish Hatchery. … Why all the trouble for some fish? Spring-run Chinook salmon and steelhead are both listed as threatened under the Endangered Species Act.
Protecting and restoring California’s populations of threatened and endangered Chinook salmon and steelhead trout have been a big part of the state’s water management picture for more than 20 years. Significant resources have been dedicated to helping the various runs of the iconic fish, with successes and setbacks. In a landscape dramatically altered from its natural setting, finding a balance between the competing demands for water is challenging.
The U.S. Bureau of Reclamation ramped up flows on the lower Klamath River on Friday morning in an attempt to reduce the risk of threatened fish from contracting a deadly parasite as had occurred in years past. The move came just over a day after a federal judge found that the bureau’s past dam operations had caused harm to threatened juvenile Coho salmon in 2014 and 2015.
The U.S. Secretary of Commerce Penny Pritzker declared a fisheries disaster for nine salmon and crab fisheries in Alaska, Washington and California in January. Of the nine fisheries, the two in California include the Dungeness and rock crab fishery and the Yurok Tribe Klamath River Chinook salmon fishery.
A federal judge is set to issue an order in the coming weeks for two federal agencies and a group of local tribes and environmental organizations to work together to develop a new water flow plan for the lower Klamath River.

Salmon are struggling to survive all along the West Coast, where runs that historically numbered in the millions of fish have dwindled into the thousands or even dozens. Environmental laws that have been put in place to see that these fish remain healthy and plentiful are not working in many places.
The owner of four dams on the Klamath River and the nonprofit corporation created to take responsibility for their destruction recently filed long-awaited applications with federal regulators to remove the dams.
At this point in the Sacramento River restoration game, one big fix will not change the outlook for endangered and threatened salmon. However, fish scientist Dave Vogel hopes that a series of smaller fixes will make a big difference.
Five years of drought have severely taxed California’s rivers, reservoirs and groundwater. The Sacramento-San Joaquin Delta – the hub of California’s water supply, an agricultural center and a crucial ecological resource – hasn’t been immune from the impacts of the prolonged drought.
At this free one-day briefing in Stockton on Oct. 25, keynote speaker Jay Lund, Director of the UC Center for Watershed Sciences, and other experts will discuss the drought’s effects on the Delta.

Less than 50 miles northeast of Chico, California, begins the 93-mile Butte Creek – a tributary of the Sacramento River. It is named after Butte County, which was in turn named for the nearby volcanic plateaus, or “buttes,” and travels through a massive canyon on its way southwest to the Sacramento Valley.
As a watershed, it drains about 800 square miles, both for agricultural and residential use. The upper watershed is dominated by forests, while the lower watershed is primarily agricultural.
The Bureau of Reclamation released water from the Trinity Reservoir early Thursday morning to the lower Klamath River to help prevent the spread a parasitic fish disease, within Chinook salmon. Supplemental flows from the Lewiston Dam will also extend into late September to protect the fall salmon run.
To prevent an outbreak of a deadly fish-killing disease, federal officials plan to begin tripling the amount of water flowing out of Lewiston Dam and into the Trinity River. … The Trinity River flows into the Klamath River and the higher flows in the Trinity are meant to aid salmon and trout in the Klamath.
As you grunt up the path in the depths of Deer Creek Canyon, the incongruous sound of a large piece of gasoline-driven machinery becomes audible over the rhythmic rumbling of the creek. … But it’s one of those things where a temporary intrusion into the wild may end up enhancing the wild for the long term.
After nearly a month in port, local fishermen are once again heading out to sea in search of the highly prized king salmon. Also known as Chinook, it’s a sleek, silver fish that boasts a high oil content, sweet flavor and a deep orange color due to its fat-laden diet of krill, anchovies and squid.
From a Hoopa Valley Tribe press release: Today, the Hoopa Valley Tribe (HVT) filed its lawsuit against the federal government for violations of Endangered Species Act (ESA) regarding its management actions on the Klamath River, California’s second largest river system.
As Operation Yurok — which the Yurok Tribe carries out each summer with help from local, state and national agencies — continues this week, Yurok Tribe Chairman Thomas P.
