I, uh, I was so impressed to see a 2000 study by Meretsky that you had us listed, and she was finding that, uh, since 1978, according to her records, that, the, the, the information shows a decline in condition in the lower basin humpback chub, '78, coincident with the decline in the population size.

Steve CarruthersGUEST
That was all the way back in 1978, and I think that's, that's the main thing that I got out of Meretsky's paper.

Steve CarruthersGUEST
Do you remember what was going on with her and, and what, what that means? That there was a ...

Steve CarruthersGUEST
Records show a decline in condition in '78, and we'd only been studying these things-

... all the way to the ocean and binding it, sequestering up those organics, it is sizable the quantity of organics that are moved through the, the arteries and veins of our river systems.

But my observations on that bluehead sucker, when we were doing our stuff after reclamation had approached me, saying that we'll give you a large research project if you hire Chuck Minkley in your organization.

Steve CarruthersGUEST
But what I'm getting at is in the early days of our trammel netting and We didn't use hoop nuts back in then.

Steve CarruthersGUEST
We were starting electrofishing, but it didn't do us a damn bit of good on flannelmouths, really, or blueheads.

And that, the, the boatmen had to be on their toes to know where we're camping, at what water level we're at, and what water level we might have in the morning when we wanna get everybody on the boats.

Steve CarruthersGUEST
I can remember at Stone Creek having to take a snout boat completely apart and hike it back down to the river, so put it back together again so we could get everybody on it.

Steve CarruthersGUEST
That's the kind of fluctuating flow that Mike's talking about, and the idea was we had some feeling that those kinds of massive fluctuations in flow were somehow affecting the fishery.

Steve CarruthersGUEST
And it's interesting, you called them bonytail a few minutes ago, and I really wanna get into that.
