Nothing like stream smallies on the surface. My local water is a little smaller than yours, and the smallies top out at about 13 inches, but there are lots in the 9 - 11 inch range. What were you catching them on? I use orange and olive stimulators. If the fish are not looking up, try hanging a pheasant tail in a size 10 or 12 off the back of a hopper or stimulator.
