I two would like an answer to this question. I have paddled my you know what off looking. I have done the best from the dock about 1/2 way out on the north side. I have seen thousands of them all over the lake but none seem to want anything to do with eating. I have seen them coming to the surface in large groups and boiling the top of the water. They might be getting ready to spawn then the bite will be on.
Try using the 1" purple mini-twister tails on a 1/64oz lead head jig. If needed, you can tip it with a redworm. I've KILLED the gills out there on this combo. Hope you find the biters. I haven't fished Mogadore yet this year. I'm addicted to those West Branch crappies!!!
