I understood it as Tuna described-likely caused by unusual conditions last winter.
This season- seeming more normal hopefully will change things back to normal -think without a lot of return fishes- think it will be mostly cookies for a while-cept for those that make it through the times.
Like to see release only for anything bigger- like a slot size limit-at least for a while.
NOT saying no steel will survive as they seem to be getting over it in the river after a while but many seem to have died.
That's all IFFFF the bait was the only factor and IFFF its cleared up this season with weather.
The jury is still out on Kings and Hos.
Lake reports all season were of few big Kings- at least on our end. I understood it that shorts likely made the numbers in the States Lake Report.
Could Kings have been dying off sooner than the Steel for some reason causing the extremely poor run- if ya call that a run ???
Saw far less spawn activity this year with them.
(yea yea it was OK in the zones--below that wasn't normal though from where I walked)
Still more questions than answers.
Next couple of years will tell about the Kings --without a definitive disease answer-- returns from the banner runs should be excellent barring other factors.
Frankly I would bet we have issues for a while with them.
Hate to be so negative.
