Anglers Catch Salmon for Science as Tracking Reveals Risks Facing Adult Fall Chinook

December 2, 2025 — Many thousands of fall-run Chinook salmon migrated beneath the Golden Gate Bridge into the upper Sacramento River to spawn this fall. About 100 of the adult fish carried small tags that signaled their location as they went.

A monitoring network tracked the fish, showing their progress online in real time as part of a joint project by scientists at NOAA Fisheries and UC Santa Cruz. They followed adult salmon through the Sacramento-San Joaquin River Delta into Central Valley Rivers and their tributaries. The scientists want to know what affects salmon survival and how many fish reach their spawning grounds.

“Are the salmon burning too much energy, and what factors affect this?” asked Miles Daniels, who leads the project for NOAA Fisheries’ Southwest Fisheries Science Center. The center operates a research laboratory adjacent to UC Santa Cruz, focusing on salmon. Adult salmon need cold water; they may stop if they hit water that is too warm. Since they do not eat on the way back upriver, delays could deplete the energy they need to complete their migration and spawn.

The research is funded by California’s State Water Board to learn more about how water temperatures influence the salmon that support valuable commercial and recreational fisheries. Officials are interested in whether water can be managed to benefit fish while still supplying Central Valley farms with irrigation water. Irrigation is vital to the production of billions of dollars worth of produce and other agricultural products every year.

Fall Chinook salmon are among today’s most abundant California salmon and have long formed the backbone of West Coast salmon fisheries. However, low numbers of returning salmon have closed California ocean waters to most recreational and all commercial salmon fishing for the last 3 years.

Promising signs for 2026 after California closes commercial salmon season for the year

April 29, 2025 — For the third consecutive year, commercial salmon fishing off the California coast will be prohibited, although there will be a limited opportunity for recreational anglers for the first time since 2022. However, officials say data indicates the industry could see a return in 2026.

Angela Forristall, salmon staff officer with the Pacific Fishery Management Council, said the decision to recommend closing the state’s commercial salmon fisheries for the year followed a challenging debate among the council and stakeholders from both the recreational and commercial fishing industries.

Forristall shared that there were several versions of the recommendation that did open commercial fishing briefly, but the data they’re seeing from populations in the Klamath and Sacramento rivers says it’s potentially too soon for major operations.

US government confirms fishery disasters took place in California salmon runs

January 6, 2025 — The U.S. Department of Commerce has determined that fishery disasters affected multiple California salmon runs, including the 2024 Sacramento River fall Chinook salmon fishery and the 2024 Klamath River fall Chinook salmon fishery.

The official determinations open up those fisheries to federal financial relief, which will be allocated to the state and Tribal governments to distribute to affected fishers and businesses.

As drought puts growing strains on fish, hatcheries serve as lifelines for California salmon

April 11, 2022 — When Shasta Dam was built on the Sacramento River in the 1940s, the government also established Coleman National Fish Hatchery about 30 miles away on the tributary Battle Creek, aiming to make up for the loss of upstream habitat by raising fish for release.

The hatchery’s staff runs an elaborate spawning operation that this year is raising 12 million fall-run Chinook salmon, supporting California’s commercial and recreational fisheries. The hatchery also raises other types of salmon and steelhead.

The adult salmon swim up the Sacramento River and into Battle Creek, then up a fish ladder to the hatchery’s holding ponds. Mechanical screens in the water are used to move the fish to the spawning building.

The fish are placed into a bath with carbon-dioxide in the water, which enables the staff to handle them. Workers lift the salmon from the water in nets, check to see that they’re ready for spawning, and separate females from males.

They club the fish and send them sliding down a metal chute. One worker hangs each female salmon from a hook, inserts a needle in its abdomen and sends air flowing to push out the eggs, which land in a colander. Another worker grabs each male fish and twists the tail, squeezing out milt that will fertilize the eggs.

California salmon are at risk of extinction. A plan to save them stirs hope and controversy

April 8, 2022 — Shasta Dam stands more than 600 feet tall, the height of a 55-story building, with a colossal spillway that towers over the Sacramento River in a curved face of concrete.

Since its completion in 1945, the dam has created California’s largest reservoir, which provides water for farms and cities across the state. But it has also blocked Chinook salmon from returning upstream to the cold, spring-fed streams near Mt. Shasta where they once spawned.

Cut off from that chilly egg-laying habitat, endangered winter-run Chinook have struggled to survive. They’ve had help from an elaborate spawning operation at a government-run fish hatchery, which is intended to function like a life-support system for the salmon.

But that support system is no longer enough. As global warming fuels worsening drought conditions and extreme heat, experts say winter-run Chinook are being pushed to the brink of extinction.

Last year, the water flowing from Shasta Dam got so warm that it was lethal for winter-run salmon eggs. Most of the eggs and young fish died. State biologists estimated that only 2.56% of the eggs hatched and survived to swim downriver, one of the lowest estimates of “egg-to-fry” survival yet.

California, Florida fish mortality pinned to drought, climate change

July 15, 2021 — California officials warned this week that salmon in the state’s Sacramento River might not survive the region’s historic drought.

The California Department of Fish and Wildlife said that “nearly all” of the endangered winter-run Chinook salmon’s juveniles might not make it through the season, according to The Sacramento Bee.

The publication reported Wednesday that a final blow, after two years of “severe mortality during the last drought,” would risk the extinction of the species — even though the agency has hauled millions of the Chinook salmon to Bay Area waters as a precaution.

Triple-digit temperatures have plagued the West, killing hundreds of people in the last major heat wave. The severe conditions have exacerbated the climate-driven “megadrought,” leading to less water and less streamflow.

Dire drought warning: California says ‘nearly all’ salmon could die in Sacramento River

July 9, 2021 — The drought is making the Sacramento River so hot that “nearly all” of an endangered salmon species’ juveniles could be cooked to death this fall, California officials warned this week.

In a brief update on the perilous state of the river issued this week, the California Department of Fish and Wildlife made a dire prediction about the endangered winter-run Chinook salmon and its struggles against consistently hot weather in the Sacramento Valley.

“This persistent heat dome over the West Coast will likely result in earlier loss of ability to provide cool water and subsequently it is possible that nearly all in-river juveniles will not survive this season,” the department said.

Given that the salmon generally have a three-year life cycle, a near-total wipeout of one year’s run of juveniles “greatly increases the risk of extinction for the species,” said Doug Obegi, a lawyer with the Natural Resources Defense Council.

The winter-run salmon endured two years of severe mortality during the last drought as well.

JAMES POGUE: Salmon is an indicator species for California’s water crisis. It’s not looking good

June 30, 2021 — In mid-June, California’s State Water Resources Control Board wrote a tragic letter. The board, which has significant powers under California’s Constitution to manage water for the benefit of California’s people and ecosystems, wrote that it would approve a plan for water releases out of Lake Shasta that risk destroying the Sacramento River’s iconic winter-run Chinook salmon population forever.

The winter-run Chinook population has already declined by 99%, down to a few thousand fish that manage to run out of the San Francisco Bay and return to spawn below a dam near Redding. Baby salmon need cold water to hatch from their eggs and grow until they’re ready to migrate to the ocean. But in this drought year, the Federal Bureau of Reclamation has proposed drawing down the levels in Lake Shasta — California’s largest reservoir — to deliver water to irrigators in the Central Valley, allowing the diminished reservoir to heat up over the summer to temperatures that when released into the river “could increase the risk of extinction significantly,” as the board’s own letter put it.

The board, whose members are appointed by the governor, could have modified the plan. Even keeping a small fraction of the water sent for irrigation to be released later could have a dramatic impact on the survival rates of young salmon hatching later in the summer. But holding back water to save fish would have set up a conflict with powerful business interests in the Central Valley.

The board seems to have been more willing to risk the extinction of a salmon run than they were to risk angering landowners and lobbyists. To save even some of the Sacramento River’s salmon population, in a year where pumping water to farms has resulted in dangerously low water flows, California has had to resort to hauling millions of young fish raised in state-run hatcheries via tanker trucks to the Golden Gate. But trucking fish is a desperate measure, one that conceals a larger crisis that is likely to make the fate of fish into one of the key political issues of California’s drought-stricken future.

California Sues Trump Administration Over Alleged Failure to Protect Species

February 21, 2020 — California is suing the administration of President Donald Trump for what it calls the administration’s failure to protect endangered species in the Sacramento and San Joaquin rivers.

California Attorney General Xavier Becerra, the California Natural Resources Agency, and the California Environmental Protection Agency filed the lawsuit on Thursday against the Trump administration in the U.S. District Court for the Northern District of California.

The attorney general said the Trump administration was adopting “scientifically challenged biological opinions that push species to extinction” and harm natural resources and waterways.

The lawsuit stressed the Trump administration’s alleged failure to protect endangered fish species from federal water export operations.

In October, the Trump administration announced a plan to divert water to California farmers, fulfilling a campaign promise made by the president.
