Quinte Fishing

First post here, been fishing Quinte for years, taking my father in law out this weekend, he tends to lose interest when I take him trolling the deeper water for trophies this time of year, but he loves jigging and trolling Thomson's in the summer, are there any walleye he might find there this time of year? I think he'd even be happy with some perch, just curious. Any advice would be apprecieated. Thanks in advance
