I saw this post and thought it might help
Walleye season opened on Saturday, May 6th. Anglers who braved the rain and wind did manage to get some walleye both in shallow and deep water. With round gobies now abundant in the lake, it may require some adjustment in the way anglers fish for walleye. The same thing was required when zebra mussels become established in the lake and the water went from turbid to clear, fishing methods needed to be changed to match the conditions. Gobies are very bottom oriented fish so sometimes just getting a foot or two off bottom will help to avoid some of them. If using worm harnesses try trolling instead of drifting, the faster speed keeps them higher off bottom and also helps to avoid some of the gobies. Using artificial lures instead of live bait can also help. Walleye tend to be "well fed" in goby waters and can be difficult to catch; full fish are generally harder to catch than hungry fish. Sometimes going for reaction bites can help, fish hit out of reflex instead of hunger. This can be accomplished by giving erratic action to your lures by speeding them out, slowing them down, stopping them briefly, giving short quick jerks with the rod, etc.
