Kent Lake is a tough lake to fish. It's the 2nd most fished inland lake in Michigan so the fishing pressure is heavy on most weekends.
The best place for numbers of bass is the portion of the lake on the other side of I-96. Fish along the drop by the freeway. I've done best with a darter head jig with either a 4" worm or 3" or 4" grub. I also like jerk baits. Perch colored crankbaits & minnow baits have done very well for me. My favorite lure for that lake is a perch Storm Wiggle Wart, which I haven't been able to find anywhere ever since Rapala bought Storm out. I've caught my biggest Michigan Largemouth out of that lake on a wiggle wart.
I was going to fish Kent today but I was too lazy to get up. I might head out there in 2 weeks.
Here's the link to my report the last time I fished Kent Lake.
