Where to start...

"Unfortunately even dropping down to size 1 hooks, and later adding corkies to help float the hooks up to keep it from under their bellies"

Hmm, I got an idea...MOVE. If you are constantly fouling fish and are incapable of fishing for them without fouling them, move to a different spot.

Wait, here comes another one...put a freakin float on and fish off the bottom. Chinook will take guts and wool fished off the bottom.

So you snagged between 60 and 80 fish and your comming back? Accidentaly snagging the ODD fish is okay, snagging numerous fish in low water is just plain snagging.

"Lots of fun...I may head back up tomorrow "

Don't bother, we got enough snaggers in this country already, why don't you do your snagging locally.

"Actually the 35 was initially fair hooked but while running down the rapids I felt it come loose and "reset" in the side. "
