You will not do badly at all using the patterns used for Trout in your area.
I know cause when I started flyfishing for panfish in the late 70's panfish flies were unheard of in Iowa.
Any black gnats, royal coachman etc. and Wooly Buggers or wooly worms work great. Matching the Hatch works for any fish, so whatever hatches in your area. Poppers are Great Fun too.
