x2. Think nymphs, little buggers, etc. Some chironomids might be good. Put one off a dropper.
Have you got a line to get it deep? That would probably be wise.
I'm about the same latitude in Kansas and have caught them on what looked to be a kind of caddis at that time of year. Standard elk hair caddis matched it. I've also got them on a foam rubber legged spider that way.
Surprisingly, on warm, sunny afternoons early in the year, I can often catch bluegills on the surface. Methinks they are taking advantage of water that warms up a degree or two.
