“There are salmon everywhere on the landscape right now”

"A little more than a year after the historic removal of four hydroelectric dams on the Klamath River, California Department of Fish and Wildlife (CDFW) scientists are seeing salmon reoccupying just about every corner of their historic habitat.
" 'The speed at which salmon are repopulating every nook and cranny of suitable habitat upstream of the dams in the Klamath Basin is both remarkable and thrilling,' said Michael Harris, Environmental Program Manager of CDFW’s Klamath Watershed Program. 'There are salmon everywhere on the landscape right now, and it’s invigorating our work.'
"While adult returns of salmon are ongoing and final estimates won’t be available until January, initial reports indicate a stronger fall-run Chinook salmon return than last year with widespread dispersal of the fish. Recent signs of salmon recovery throughout the Klamath Basin include:
- The Oregon Department of Fish and Wildlife and Klamath Tribes report seeing widespread salmon spawning within the Oregon portion of the Klamath River, including within multiple tributaries upstream of Klamath Lake where salmon haven’t been seen in more than century.
- Fish-counting stations on newly accessible tributaries within the former reservoir footprints in California have recorded 208 adult Chinook salmon in Jenny Creek and 260 adult Chinook salmon in Shovel Creek to date. While multiple state and federal agencies,Tribes and non-governmental organizations are monitoring salmon throughout the Klamath Basin, CDFW is particularly focused on monitoring these newly accessible tributaries. CDFW field crews are surveying regularly for salmon nests and adult fish.
- CDFW snorkel crews this summer documented juvenile salmon and/or steelhead occupying nearly all of the newly accessible tributaries in the reservoir footprints. In Fall Creek, one of the newly accessible tributaries upstream of the former Iron Gate Dam location, approximately 65,000 wild juvenile Chinook salmon were counted.
- CDFW’s Fall Creek Fish Hatchery, a $35 million state-of-the-art facility in its second year of operation, began spawning returning fall-run Chinook salmon in mid-October. To date, the hatchery has spawned 416 female fish and collected roughly 1.27 million eggs – four times the number of salmon spawned this time last year. More than 1,200 Chinook salmon have entered the hatchery so far.
- Temperature monitoring in 2024 and 2025 along the mainstem Klamath River following the removal of the four dams reveals the return of natural, seasonal fluctuations of water temperatures benefiting salmon. Post-dam removal water temperatures are cooling sooner in the fall when adult fall-run Chinook salmon are returning and need that cool water most followed by warming temperatures in the spring when juvenile salmon are rearing and out-migrating to the ocean.
- Scientists are seeing a lower prevalence of Ceratonova shasta – or C. shasta – a parasite that plagued juvenile salmon prior to dam removal. Harmful algal blooms in the Klamath River are smaller now and less frequent since dam removal.
A primary goal of Klamath River dam removal was the reestablishment of viable, wild, self-sustaining populations of salmon and other anadromous fish species for conservation, for their ecological benefits, and to enhance Tribal, commercial and recreational fisheries."
