Teach, sorry bud...I should have been more specific.

I was in Clarkston...we were fishing the Snake/Clearwater confluence. Of course, that doesn't help a whole lot since you were asking about the Tucannon/Lyon's Ferry area. Again...sorry about that. Didn't mean to lead ya to believe I was actually fishing Lyon's Ferry. The only thing I know about that area right now is what I saw when I drove through there.
My brother hits the steelies almost every day. Since my last trip was a few weeks ago I'll give him a call tonight and see what depth he's hittin' them at right now. I'll let ya know what I find out.
FYI: If you drive through Washtucna and past the Palouse Falls turn-off, keep your eyes open for the Muleys. I spotted a really nice 4X5 in there on that same trip. All in all I saw about 100 head, about 10 small bucks (Spikes and forkeys) and that one big one.
Again, good luck and I'll let ya know what I find out.
