I have heard there are some cold water springs through out the river that keeps them alive. But was only talk from anglers.
When I did hazelbaker last, I did really well from the yak. Dragged a ZMan jerkbait or fluke jerkbait and would give it a pretty constant pop, pop, pop, rest and repeat. Got a few with the TRD that way too. Last year in the Kiski, did the same with tube jigs and did well.
I struggle with the senkos while drifting. Seems like they seem to work better while anchored or wading. I did get a few with them, but action was so much better for me with the dragging approach. I’m sure it changes daily though.
I’ve had my kayak for about 20 years. Used it a good bit for 2-3 years, bought a boat and it sat unused for about 10 years. The past year I think that I used it 5 times, which is by far the most that I have used since the first few years. I will try to use it a bit more next year. I’ll have to explore more areas that I can paddle up and drift down. Do you know if there is a public launch point at Layton/Hazelbaker area?
