Local Tournament Help

this weekend I am fishing a tournament with a friend. We will be fishing on a 60 acre man made lake. I got lots of bites last night (missed a 3.5 up shallow on the wacky rig) when it was 75 and sunny clear skies.today, I had lots of trouble getting anything. I was to lazy to go out in the boat. It was 63 and rainy overcast. The main forage in the lake is bluegill and perch. One side is shallow with semi submerged weeds. Got several bites there. the other side has a deep channel of 8-15 feet. along that bank are boulders. the bottom is mucky and weedy. there are several docks. average bass is 2 pounds. size but not quantity. I need help. thanks
