Habitat in both N Fk and S Fk was sufficient to support large numbers of returning adults in the early and mid 1980's. Freshwater habitat conditions have not deteriorated in the 30 years since then, so a reasonable person would have to conclude that freshwater habitat there is still capable of supporting healthy numbers of steelhead.
Remember that during the mid 1980's, rivers all across W WA were also seeing large numbers of steelhead returning, followed by an abrupt decline in returns thereafter. Steelhead returns in streams everywhere followed much the same pattern as the Toutle.
I'm not advocating one way or the other on the selection of the Toutle as a gene bank candidate, just saying that judging the quality of the habitat in the Toutle (or any other river) based on adult returns can lead to false conclusions because fails to incorporate the ocean influence that is currently driving the low returns.
You know, I certainly don't have it figured out but let's take a look at something for a second.
As much as I hate to admit it, I'm 90+% sure this is going to work...
Example, the Lewis River is the only river in the LCR that has a self-sustaining population of Fall Chinook. One thing that is very interesting is that it hasn't been planted with hatchery fish since the early 1970's. So again, it's a self-sustaining population of Fall Chinook capable of all the CR netting and in-river harvest. It has shut down a handful of years but for the most part it has sustained harvest. How is it the only river in the LCR that's like it? Keep in mind it's escapement is 6600 returning fish, that's 6600! Not the measly amounts all the other rivers in the LCR get with their hatchery plants..... I heard from some reliable resourse's (spawn counter's) the Lewis received 25,000+ fall kings returned in 2013.... That's amazing!
The Lewis has no hatchery plants that have jacked up the native population, that's how.... It certainly isn't a pristine watershed at 21 river miles in which 7 of them are tidewater. It certainly isn't pristine habitat as it's been rip-rapped and channeled in many places and it certainly isn't pristine habitat with it's DAM....
The Gray's River is one of the few left that meets escapement some years with wild winter steelhead, it does get hatchery fish but has a hatchery on a side tributary which sucks most hatchery fish from the river and keeping them from spawning with the natives...
The Kalama is second best at meeting escapement for steelhead, ironically it has a falls/hatchery that selects and sorts hatchery fish out and only allows wild fish to the spawning grounds....
It does suck losing hatchery steelhead plants, without question... I hope they're onto something. I'd love nothing more than to have what my dad and friends had in the late 70's and early 80's before the steelhead #'s diminished.. I'd love to see those 20+ pound natives coming in full force....
How we didn't see this in the early 90's baffles me... It's truly sad to have seen it go this long. Hopefully it's not too late. But I'm all about the EFL going to a gene bank. I hope in 5-10 years I can float that river and see those big pigs I used to catch.
