Locations look to be anywhere from Toledo water intake area and east to the reefs. NE of the reefs towards North Bass, then all the water east of Kellys, north of Vermilion and Lorain and Geneva has been hot where our #2 boat has been for 6 weeks taking huge coolers of eyes. A 300 pound cooler of eyes taken this past Saturday in Geneva ! Perch has heated up all over the lake with good catches from same areas mentioned above.
