CM is probably Christine McWilliams

ah, the vet, of course.

If you want it to be fish farm related send it to AM she has her ways.

Yes I ment KM oops

Same thing happens from the displacement and wake of jet boats this time of year if run irresponsibly close to shore where these fish are migrating. You see a lot of it on the Harry when cutty fishing.
I am a boat owner and not passing blame, just another possibility.

I have seen it as there well but it is not extensive, just a few fry here and there. Sticklebacks in the fall. I wonder if heavy boat traffic is causing accelerated erosion however. I'd bet that's more of a problem in summer when the water is higher and ski boats etc are active.

I agree not extensive, but similier numbers being reported here.
"couple at Gill"
"6 at Agassiz"
"16 or so"

Not trying to down play it either, as any loss is something our fisheries can not afford right now.

anyone know how much turbidity can those smolts handle?  I find it incredible how cloudy the water can be and that the fish can tolerate it.

Good question, here's why it's difficult to come up with a means of measuring turbidity as it relates to mortality.

I believe what the turbidity is caused by, ie. the fines, is important as well. Some forms of silica are hard on gill filaments so this could be a possible cause of death, or one of many.

I looked at the water today, no visibility at all, water is dropping but will be on the rise big time soon.
