Small Skykomish Steelhead

[RC]

I spoke to a hatchery worker a few years ago that told me the changes we’re seeing is the result of the WFC decision that changed hatchery management for skamania steelhead. I believe they are using a stock of steelhead tied more closely to the Snohomish system, which are smaller?  Hopefully someone else can shed some more light on this, but bottom line is that this is the future of steelhead fishing on the Snohomish system. The worker also told me all the new pens up there are for raising chinook to come back to reiter, but who knows if we’ll be able to fish for them.

I caught 14” rainbows in the upper Sky drainage thin blue lines this past year with almost regularity. A 16” fish(rainbow) on the main river seems totally conceivable without any other thoughts coming to mind. There are definitely at least some resident fish in the main stem.

On the right track here, I believe. Not all hatchery released Steelhad smolts migrate to the salt. Some residualization takes place, particularly when the smolts get too big in the pond, or become precocious. At some facilities, smolts are allowed to volitionally leave the pond when ready; after a period of time, those that don’t leave are considered residualized and are planted in lakes.

The Skamania stock are the summer fish. Winter fish have always been Chambers Creek stock. They are supposed to be using wild summer broodstock for the summer program now. They may not be as big as Skamania stock but still a good move as far as I'm concerned. I'd be very surprised to see them ever use wild winter fish for their hatchery stock based on run timing alone.

I heard that during covid the state opened the gates and let all the fish out. So they were letting smolts out and that's what's returning now. The fish are returning a year before they should be.

I don't think that's how it works. Steelhead are biologically tuned to head to salt at a certain age. Just because they are let loose from the ponds doesn't mean they head straight to the salt.

We floated the river today and I l only landed one fish. Nice Rainbow  that was 17-18” or so. Pretty slow day of fishing.

Could it be a combination of issues? Maybe food quality/supply in saltwater?
Maybe released early and set up as residents? Brood stock?  I moved a few years ago from that area, Lake Stevens, and I sure do miss fishing the Sky. Beautiful country.

Salmon guys have theorized for a long time that if you have a lot of Jack's around one year, the following years adult run should be robust. That's all hypothetical though.

There's a lot wrong with the Skykomish system but most of it happens down in the Snohomish and tide water. The number of pinnipeds in the lower end of that river is extreme and smolt hardly have a chance.

Most of our rivers don't have enough feed in them to support many smolt that spend a year or more in the system before heading out because the robust runs of late fall spawning salmon (chum mainly, silvers too) have become so depressed that the biomass in the river continues to decline. We need those carcasses to decompose in the rivers to grow bugs for those smolt to eat. It's a vicious cycle.

Not certain on this but there was a lawsuit filed a few years ago and the state was forced to dump a bunch of steelhead into Rock Lake at my parent's place in Whitman County. I believe it was because they were not considered native to the river they intended to stock on the West side. Could this be what your referring to?

I  fed fish in a rearing pond in Skykomish that were released into the South fork of the Sky. Part of the exercise was to clip a fin at Reiter Hatchery first. Back then we caught many Hatchery fish for years. Of coarse their off spring were native. Used to be some really nice steelhead caught back then.
