You may run into heavy hatches of Zebra Caddis midday through afternoons on the Hoosie. Itís large, size 10-12. Try a fluttering caddis style pattern with gray body, brown mottled wings and brown hackle for the dry size 10-12, or swing big size 6-10 Brown and Blue Deep/Emergent Sparkle pupa (body mix of olive brown and blue, bubble light tan, light brown wings of deer hair or lemon wood duck and head of dark purple marabou or dubbing or black bead.) these can also be great for smallmouth if you fish warmer water sections.
