🍂🐟 Fall means prime time to help McCloud River Redband Trout! We teamed up with @CaliforniaDFW & Streamwise to build deeper, longer-lasting pools that protect this state species of special concern during droughts. Next up: monitoring results & expanding habitat restoration!

CA's rivers face a new threat – golden mussels. These tiny filter-feeders harm fish, clog pipes, & spread fast. We're partnering with @CaliforniaDFW, @Inyo_NF, & others to develop management strategies protecting Sierra watersheds. See how YOU can help:

🐟 🏗️ A few weeks ago, our Iron Canyon Fish Passage project broke ground at Big Chico Creek. The project will restore access for steelhead & spring-run Chinook to their historical distribution in the Creek. Completion slated for 2027! More via @KRCR7 https://t.co/NKu023j3MN

🚧🐟 Construction is underway on the Scott River! Led by the Yurok Tribe, w/ Farmers Ditch Co. & CalTrout, this project will restore fish habitat, improve flows, & balance ag + enviro needs—key to post-dam recovery across the Klamath River watershed. 🔗 https://t.co/33LBXFlYRb

Last night, 200,000 #salmon smolts were released at Point Richmond with GSSA, CDFW, EBMUD, the City of Richmond & Richmond PAL. Over 20 kids joined Salty Lady Sportfishing to learn about salmon and witness the release—many experiencing the bay for the first time!

🌊 There's a lot of chatter around dam removal on the Eel. We're cutting through the noise to share the most important facts (hint: economic reasons often drive dam removal). 🔍 Dive into our latest blog post to get the full story! https://t.co/igjCkGQKQI

[Golden State Salmon Association @goldenstsalmon]

The restoration of Putah Creek has led to the return of Chinook #salmon completing their natural life cycle. UC Davis researchers analyzed fish found between 2016 & 2021, revealing some returning salmon originated there and were not strays from elsewhere

Putah Creek is one of the greatest env'tl comeback stories I've been a part of. And as Ethan's new paper in @ESAApplications shows (summarized in blog 👇) - the proof is in the pudding/data. And with new models, we can learn how to make env'tl flows/mgmt even better still 💪🏞️🐟

History made on the Eel River! 🚨 A landmark agreement will remove two obsolete dams, creating CA’s longest free-flowing river 🌊, restoring salmon runs 🐟 & securing water for communities. Led by Round Valley Indian Tribes & key partners. Learn more: https://t.co/COqR1HZd3J

This winter, 25K acres of Sacramento Valley rice fields are growing food for endangered Chinook salmon! 🌾🐟 Scientists say 3.5M fish could double in weight thanks to nutrient-rich water from the fields. Bigger fish=better survival chances! 🐛➡️🐟 Watch: https://t.co/eoxGQJvZc2

🌊 Meet Farrah Tyler, a CalTrout Fellow mapping the future of the Eel River watershed! Using GIS, she’s protecting threatened salmon & crushing it as a triathlete. 🐟 Her advice: "Follow environments you love & people doing good work.” 🌎 Read more: https://t.co/DFy0SuJmEV

The Yurok Fisheries Department is analyzing scales from the 1st cohort of salmon to spawn above the former Klamath River dams in a century.
The scale samples came fish that reproduced in Spencer, Jenny, Shovel, and Fall Creeks as well as the main-stem Klamath.

This was a fun blog to contribute to. Those that know me can probably guess which ones I added or worked on most 😉

Happy holidays all! 🎄🎅

Big congrats to Rachelle Tallman on publication of her experimental salmon-rice work in River Research and Applications! Thsi work shows how growth & in-field survival of juvenile Chinook salmon is high in rice. These results are impt for managers 🧵⬇️
