thanks to all.
I have personally seen a steelhead taken from the head of a riffle.
And I've also read that trout can hold and be taken from riffles. and steelheads are kinda large trout, right? from reading I also know that steelhead doesnt like an open place and it's highly unlikely to find him in just a few feet of clear water where he can be seen.

but we are not talking about low and clear water on the sky anymore, it jumped up 9 feet in just one night
things get easier - let's welcome new fresh fish
