Clouds can be a walleye anglers best friend. Walleye feed better in low light conditions such as early morning, evening and at night. On cloudy days, walleye will usually remain more active and some fish will move shallower than they would if it were sunny. For example, on a clear water lake, you may have to fish 20 to 30 feet deep on a sunny day during the middle of the day to catch walleye, but on a cloudy day, you may be able to find walleye in 10 to 20 feet of water during the middle of the day. In darker water, walleye may move up into 5 to 10 feet of water from 10 to 20 feet of water. For most anglers, it’s easier to catch walleye when these fish move into shallower water.
