ROD “summer baseflows” continue to be released from Lewiston Dam at about 450 cubic feet per second until October 15 – when flows reduce to 300 cubic feet per second. Current river flow gauges can be found on our homepage, click here<https://www.trrp.net/> and scroll to the middle of the page.
Air temperatures and sun exposure are slowly falling as we approach the fall equinox and river temperatures are following suit. The start to the fall season marks the beginning of the fall run chinook who are making their way upriver. We have heard reports of spring run chinook redd creation and spawning in the upper river near the Sven Olbretson restoration site. Additionally, crews from the California Department of Fish and Wildlife and the Yurok Tribe have begun their fall spawning and carcass surveys.
Fish health in the upper Trinity remains favorable while temperatures in the lower Trinity are warmer than desired and remain in “yellow” cautionary status.

A group of pink salmon return home to the waters where they were born, bringing with them a pulse of nutrients that helps drive stream and forest ecosystems. From old-growth trees to aquatic insects, hundreds of species rely on the large amount of marine-derived nutrients that salmon provide. As salmon numbers have declined throughout the Pacific Northwest, this important ecological resource has been lost from many forest and river environments in the region. It’s now estimated that only 3-7% of the nutrients salmon deliver make it back into freshwater environments.
David Herasimtschuk
“As humans, our everyday lives are sustained by the behaviors and interactions of forest organisms,” photographer David Herasimtschuk writes of old growth forests. “Yet, because these processes and relationships occur in places and at scales rarely observed, our connection with forest biodiversity and the role it plays in nurturing our well-being often goes completely unnoticed.” Continue Reading …<https://www.npr.org/sections/the-picture-show/2024/09/03/g-s1-5057/photographer-captures-life-in-old-growth-forests>

Teams and Technology Trace Klamath River Recovery by Tracking New Salmon Returns<https://www.fisheries.noaa.gov/feature-story/teams-and-technology-trace-klamath-river-recovery-tracking-new-salmon-returns?utm_medium=email&utm_source=govdelivery> | NOAA Fisheries
The removal of four dams on the Klamath River will reopen more habitat<https://www.fisheries.noaa.gov/feature-story/worlds-biggest-dam-removal-project-open-420-miles-salmon-habitat-fall> to Pacific salmon than all previous dam removals in the West combined. Now it will have a monitoring program to match—designed by top salmon scientists to track when and how many fish of different species return and where they go.
“The world’s eyes are on the Klamath Basin right now,” said Damon Goodman, Mount Shasta-Klamath Regional Director of CalTrout, who helped develop the monitoring program with other fish scientists, tribes, and state and federal agencies. “It’s our responsibility to have credible, transparent, and solid data that tells us—how is this working for the fish?” Continue reading …<https://www.fisheries.noaa.gov/feature-story/teams-and-technology-trace-klamath-river-recovery-tracking-new-salmon-returns?utm_medium=email&utm_source=govdelivery>

Watching native fishes vanish<https://californiawaterblog.com/2024/09/01/watching-native-fishes-vanish/> |California Water Blog
By Andrew L. Rypel and Peter B. Moyle
It’s an odd, disturbing feeling – watching populations of native fish species collapse and then disappear. Sometimes it happens quickly, other times it’s a series of slowstep change events. The end result is the same though – smaller populations, extinctions, less biodiversity. We put up a little fight, and occasionally have moderate success. But by and large, the overall trend is down, the pace of change quickening, and it is relentless. We’ve watched it over our careers, and maybe some of you have too. Either as biologists or water professionals, or perhaps as long-time readers of this blog. This summer has been no different. It has been an avalanche of stories, all with variations on this theme. Here, we provide a synopsis of some recent events, along with wider thoughts on what watching this happen means. The following stories are by no means comprehensive, so if there are additional items we missed, feel free to discuss and link to them in the comments below.

--Trinity River Watershed: Animal Spotlight--

Common Green Darner  Anax junius
If you’ve been lucky enough to spend time on the Trinity River lately, you will notice a plethora of brassy-green colored dragonflies hovering above the river fervently darting to and fro. The species you are most likely viewing is the common green darner Anax junius. Common is in it’s name, and that is certainly the case, for this ancient yet abundant species that has been on the earth for over 300 million years, that’s even before the dinosaurs!
