CDFW adjusts salmon releases in Sacramento River
In a significant shift of California's salmon strategy, the California Department of Fish and Wildlife (CDFW) has begun releasing juvenile fall-run Chinook salmon from CDFW-operated hatcheries into the main stem of the Sacramento River for the first time.
The release of approximately 3.5 million fall-run Chinook salmon smolts into the main stem of the Sacramento River occurred in mid-April near Redding and Butte City. The fish originated from increased production at CDFW's hatchery operations at the Feather River Fish Hatchery and the Mokelumne River Fish Hatchery. CDFW-operated salmon hatcheries historically have supported populations on their home rivers elsewhere in the Central Valley.
'We strongly support the California Department of Fish and Wildlife's bold decision to release salmon smolts directly into the main stem of the Sacramento River – a historic first that gives juvenile fish a fighting chance at survival,' said Scott Artis, executive director at Golden State Salmon Association. 'With Sacramento fall-run Chinook returns at crisis levels, and fishing families and businesses having been impacted since 2023, this innovative move is exactly the kind of action we need. We applaud the tireless hatchery staff who made this possible and stand with them in the effort to rebuild our salmon runs and revive California's commercial and recreational fisheries.'
'The naturally spawning Sacramento River salmon populations have been the primary driver of California's commercial and recreational salmon fisheries for decades,' said Jay Rowan, CDFW Fisheries branch chief. 'Poor spawning and migration conditions for fall-run Chinook during the past two droughts have resulted in low returning adult numbers the last three years. These low adult returns not only affected fishing seasons but also reduced the number of spawning adults and, consequently, the number of juvenile salmon available to take advantage of the good river conditions to rebound this part of the run. The extra effort by our hatchery staff to maximize production has allowed us to take measures this year to speed up the rebuilding of these critical Sacramento River natural spawning areas. This significant shift in strategy speaks to CDFW's long-term commitment to boosting these important salmon populations.'
The 3.5 million fish being released into the main stem of the Sacramento River are part of an additional 9.7 million salmon produced in 2025 above normal production goals, funded in partnership with ocean and inland fishing groups. CDFW's hatchery operations, in coordination with the state Department of Water Resources, East Bay Municipal Utility District, and the federal Bureau of Reclamation, will raise and release more than 28 million fall-run Chinook salmon in total in 2025.
CDFW's Sacramento River salmon releases are being timed with increases in water flows that have been shown to improve survival in their journey to the Pacific Ocean and also with salmon releases from the U.S. Fish and Wildlife Service's Coleman National Fish Hatchery in Shasta County to overwhelm predators with a massive volume of released fish.
Additionally, CDFW has provided the Coleman National Fish Hatchery with 10 million salmon eggs to help meet its production goals and offset low adult salmon returns to the federal fish hatchery located on Battle Creek about 3 miles east of the Sacramento River in Anderson.
The juvenile salmon released into the Sacramento River are expected to imprint on the main stem during their migration to the ocean, which in three years upon their return to freshwater is expected to increase the number of adults utilizing important natural spawning areas within the main stem.

California's Yurok Tribe gets back ancestral lands that were taken over 120 years ago
ON THE KLAMATH RIVER, Calif. (AP) — As a youngster, Barry McCovey Jr. would sneak through metal gates and hide from security guards just to catch a steelhead trout in Blue Creek amid northwestern California redwoods. Since time immemorial, his ancestors from the Yurok Tribe had fished, hunted and gathered in this watershed flanked by coastal forests. But for more than 100 years, these lands were owned and managed by timber companies, severing the tribe's access to its homelands. When McCovey started working as a fisheries technician, the company would let him go there to do his job. 'Snorkeling Blue Creek ... I felt the significance of that place to myself and to our people, and I knew then that we had to do whatever we could to try and get that back,' McCovey said. After a 23-year effort and $56 million, that became reality. Roughly 73 square miles (189 square kilometers) of homelands have been returned to the Yurok, more than doubling the tribe's land holdings, according to a deal announced Thursday. Completion of the land-back conservation deal along the lower Klamath River — a partnership with Western Rivers Conservancy and other environmental groups — is being called the largest in California history. The Yurok Tribe had 90% of its territory taken during the California Gold Rush in the mid-1800s, suffering massacres and disease from settlers. 'To go from when I was a kid and 20 years ago even, from being afraid to go out there to having it be back in tribal hands … is incredible,' said McCovey, director of the Yurok Tribal Fisheries Department. ___ EDITOR'S NOTE: This is part of a series of on how tribes and Indigenous communities are coping with and combating climate change. ___ Land Back is a global movement seeking the return of homelands to Indigenous people through ownership or co-stewardship. In the last decade, nearly 4,700 square miles (12,173 square kilometers) were returned to tribes in 15 states through a federal program. Organizations are aiding similar efforts. There's mounting recognition that Indigenous people's traditional knowledge is critical to addressing climate change. Studies found the healthiest, most biodiverse and resilient forests are on protected native lands where Indigenous people remained stewards. Beth Rose Middleton Manning, a University of California, Davis professor of Native American Studies, said Indigenous people's perspective — living in relation with the lands, waterways and wildlife — is becoming widely recognized, and is a stark contrast to Western views. 'Management of a forest to grow conifers for sale is very different from thinking about the ecosystem and the different plants and animals and people as part of it and how we all play a role,' she said. The Yurok people will now manage these lands and waterways. The tribe's plans include reintroducing fire as a forest management tool, clearing lands for prairie restoration, removing invasive species and planting trees while providing work for some of the tribe's more than 5,000 members and helping restore salmon and wildlife. Protecting a salmon sanctuary One fall morning in heavy fog, a motorboat roared down the turbid Klamath toward Blue Creek — the crown jewel of these lands — past towering redwoods, and cottonwoods, willows, alders. Suddenly, gray gave way to blue sky, where an osprey and bald eagle soared. Along a bank, a black bear scrambled over rocks. The place is home to imperiled marbled murrelets, northern spotted owls and Humboldt martens, as well as elk, deer and mountain lions. The Klamath River basin supports fish — steelhead, coho and Chinook salmon — that live in both fresh and saltwater. The Klamath was once the West Coast's third largest salmon-producing river and the life force of Indigenous people. But the state's salmon stock has plummeted so dramatically — in part from dams and diversions — that fishing was banned for the third consecutive year. 'We can't have commercial fishing because populations are so low,' said Tiana Williams-Claussen, director of the Yurok Tribe Wildlife Department. 'Our people would use the revenue to feed their families; now there's less than one salmon per Yurok Tribe member.' Experts say restoring Blue Creek complements the successful, decades-long fight by tribes to remove the Klamath dams — the largest dam removal in U.S. history. This watershed is a cold-water lifeline in the lower Klamath for spawning salmon and steelhead that stop to cool down before swimming upstream. That's key amid climate-infused droughts and warming waters. 'For the major river to have its most critical and cold-water tributary … just doing its job is critical to the entire ecosystem,' said Sue Doroff, co-founder and former president of Western Rivers Conservancy. Altered lands, waterways For more than 100 years, these lands were owned and managed for industrial timber. Patchworks of 15 to 20 acres (6.07 to 8.09 hectares) at a time of redwoods and Douglas firs have been clear cut to produce and sell logs domestically, according to Galen Schuler, a vice president at Green Diamond Resource Company, the previous land owner. Schuler said the forests have been sustainably managed, with no more than 2% cut annually, and that old growth is spared. He said they are 'maybe on the third round' of clear cutting since the 1850s. But clear cutting creates sediment that winds up in streams, making them shallower, more prone to warming and worsening water quality, according to Josh Kling, conservation director for the conservancy. Sediment, including from roads, can also smother salmon eggs and kill small fish. Culverts, common on Western logging roads, have also been an issue here. Most 'were undersized relative to what a fish needs for passage,' Kling said. Land management decisions for commercial timber have also created some dense forests of small trees, making them wildfire prone and water thirsty, according to Williams-Claussen. 'I know a lot of people would look at the forested hillsides around here and be like, 'It's beautiful, it's forested.' But see that old growth on the hill, like way up there?' asked Sarah Beesley, fisheries biologist for the Yurok Tribe, sitting on a rock in Blue Creek. 'There's like one or two of those.' Fire bans, invasive plants and encroachment of unmanaged native species have contributed to loss of prairies, historically home to abundant elk and deer herds and where the Yurok gathered plants for cultural and medicinal uses. Western Rivers Conservancy bought and conveyed land to the tribe in phases. The $56 million for the conservation deal came from private capital, low interest loans, tax credits, public grants and carbon credit sales that will continue to support restoration. Restoration plans The tribe aims to restore historic prairies by removing invasive species and encroaching native vegetation. The prairies are important food sources for elk and the mardon skipper butterfly, said Kling from the conservancy. Trees removed from prairies will be used as logjams for creeks to create habitat for frogs, fish and turtles. The tribe will reintroduce fire to aid in prairie restoration and reestablish forest diversity and mature forests to help imperiled species bounce back. Members know its going to take decades of work for these lands and waterways to heal. 'And maybe all that's not going to be done in my lifetime,' said McCovey, the fisheries director. 'But that's fine, because I'm not doing doing this for myself.' ___ The Associated Press receives support from the Walton Family Foundation for coverage of water and environmental policy.
