The fish aren’t goin to return past iron gate dam. Anadromous fish return to spawn in the creeks in which they were born. The salmon have spawned in the creeks below iron gate for decades, hence that is where they will return. Removing the dams will improve the overall health of the river, but it is going to take serious work beyond removing the dams to get the fish to utilize all that previously inaccessible river.
if the habitat is there they will find it, no help needed. ‘salmon-king of fish, the demise of a species’ is a great book on the subject. covers biology of the fish, regard through history, and the past impacts, and the future for them. it’s a good read,
Salmon are really good at returning to their native spawning ground…
But up to 15% of chinook “stray” and find new habitat.
The evolutionary advantage is obvious. They gotta mix up those genes and discover new habitat.
They built a hatchery on jenny creek just above the first two dams and released a lot of salmon already. As before it will be mostly a hatchery run in the upper river.
Then how are there atlantic salmon in East lake? If spawn are exposed to the trace chemicals of a particular spawning grounds they will return there. When they had the aquaculture farm in Newport the returning fish would literally jump onto the conveyer belt for processing.
The folks that study such things for a living say otherwise, and the fish, (with some help yes) will return past that dam. All of them actually.
USGS? Hundreds of miles: https://www.usgs.gov/faqs/how-far-do-salmon-travel
Col. River inter Tribal Fish Comm? Even farther. https://critfc.org/fish-and-watersheds/columbia-river-fish-species/columbia-river-salmon/
(snip) “Spring chinook were extinct from the Walla Walla River for more than 80 years. The last run of more than a few fish was reported in 1925. Nine Mile (Reese) Dam, constructed in 1905, preceded the disappearance of spring chinook and caused the Walla Walla River to run dry each summer for nearly 100 years.”
2001, river flows all year again. 2004 first 200 “reprogrammed” fish return. 2009, 1100. 2012, 5,500 and an enough later on to open a fish hatchery of salmon native to the once dry river. (snip)
Guess what came back to the Walla Walla? The salmon. Guess what also will come back to the Klamath with some help? Also salmon. And other fish.

Art brings us back to that perfect state of mind–reality. Thank you Terry Torgerson.

It’s weird that you would write with such confidence when you have such little knowledge of the subject.
Anadromous fish, such as salmon, return to the general area where they were born, guided by environmental cues, not just the exact creek.
that’s not what happened in New England and those rivers were impassible for 100s of years.
You mean serious work leading to hatchery releases up there? 🙂

They were planted there
