Excellent info being shared here when it comes to River Boaters verses River Waders. I'll tell ya'll what though...I've been standing in waist high water when a boat came through and it didn't make any difference at all as far as catching is concerned...for right when that boat past me I was reeling in just after he passed and I hooked into one. I have read in magazine articles that in the major rivers like the Ohio and Mississippi that a good place to try is behind the path of a barge because they tend to stir up all kinds of stuff and the fish know it and become a little more aggressive. I guess this same train of thought holds true for any river big or small.
