Summertime brings walleyes to sand bars and general shallow spots in the water, where they can easily get to feed on minnows and crayfish, but they move into deeper waters where they are attracted to slightly larger fish. Generally, the fish down below are more appetizing to the Walleyes than whatever your bait is, so it is best to start catching them earlier on.

In the fall, the Walleyes start to move into generally deeper waters, where again, there are plenty of smaller fish to eat such as the minnows. The middle of September is when Walleyes drop to an average of 30 feet deep, where they float around steep slopes. When Walleyes enter deep water, their feeding is more aggressive, particularly toward midday, so if you are fishing in the autumn you will have the best luck midday.

Putting three or four minnows on a slip-sinking rig work the best, because the Walleyes would go right after them, so you can catch the largest Walleyes in this timeframe. Obviously, you should use live bait, because Walleyes are too smart to really fall for a plastic lure or other such item. Well, they might, but live bait will often work better.

Walleyes, at this time of year, tend to move rather slowly at night because the water is cooling down, so you can catch larger Walleyes at night. It’s not an easy fish to catch, but it gives good bragging rights.
 
Finally, in the winter, when ice fishing starts, Walleyes will linger at around 10 to 12 feet, where there will be rather lethargic fish for them to eat.

They’ll be at the lake flats, and they go to 20 feet in January. Depending on what the snow and other weather looks like, the Walleye might move to shallower or deeper waters in winter. The brighter the day, the deeper they’ll go to keep themselves shrouded.
