I always start by looking for a "hard edge" like a harbor sea wall or thick bullrushes with 3-6 feet of water running up against it.
53 degrees and rising is what kicks 'em into gear. These fish will still live in the 5'-15' stuff for a few more weeks but will picnic in the shallows on warm afternoons.
There is just one more week to go before full-on Walleye mode, time to hit the shallows!
Cheers and hook-sets!
