I usually use 9/0 and big green sunfish especially if im targeting flathead. The deep water can be productive when the lake starts heating up around mid to late summer.At night big catfish come up shallow to feed if you're gonna be daytime fishing you may need to try deeper or good cover.
If you are going to be here early to mid june the fish should be either pre spawn or on the nest so the creek and river arms should be your main focus.
