throw some of those jiggin rod holders in front of the holes and get more lines out there man. I'd chum the heck outa the hole your jiggin too.
I fished that lake quite a few times last year, tried different bait, different depths, spots, everything, it just seems to be a slow lake, or slow year, cause everyone else I fished with wasnt getting much either.it always seemed to be a one fish a day kinda lake. there are some huge pike in there though.
