We fished that same area sunday. The perch were schooled up real tight,you would see the pack come on the screen of the fishfinder and all the rods would catch doubles and triples as fast as you could get the rods back down then the screen cleared and nothing,wait a couple minutes and the same thing... all big fish. Just wondering what ramp did you use? We put in at the ramp way down the channel,the docks were out for the year. Can you pay to use the ramp down by the end of the no wake? I drove over those hump too,on the fishfinder you could see the fish sitting right on the sides of the sharp dropoffs. The hump on the north side that goes from 16 to 12fow had a lot of fish on it, I want to try it just before dark one night this week.
