Consider that weather is a huge factor in how aggressive a fish is.

Stable weather means a good bite.

A post-cold front is always tough.

Never remain on the water in the presence of thunder and lightning, although some of the best fishing may occur before high pressure pushes out a low pressure front.

Use sonar to find walleyes after they migrate to deeper water.

Many anglers fish structure, but Johnson fishes walleyes. He uses sonar to hold position over structure, but doesn't drop a lure until he sees fish.

For suspended fish: Motor quickly through open water until you spot suspended forage surrounded by walleyes. Work a crankbait or spinner rig around the edges and through the middle until you catch all the biters.

One of Johnson's hard-and-fast rules is always use lively fresh bait when fishing for walleyes. He stores his leeches in a leech locker in his livewell to keep them healthy and active. His night crawlers are always kept in fresh bedding in a cooler, so when he threads one onto a No. 4 hook, the worm is wiggling. When the "crawler" goes limp, it's time to put on a new one. Minnows also must be strong, and active, lively bait catches more fish.
