When I lived in northern ontario once the mid-summer heat & sun drove the walleye into deeper water we would fish them at night as they came into the shallows to feed once the water temp dropped a couple degrees. We used to fish them in real rocky areas with medium to large round rock. Our two favorite baits were a crayfish suspended just off bottom under a slip float or a leopard frog hooked to a floating jig and tossed out on the surface. Caught most of our larger walleye that way. On the Ottawa River when the walleye were feeding heavy on crayfish they would be coughing them up as you reeled them in. We would see lots of crayfish parts being spit out. Ottawa River crayfish were often an orangey/reddish colour. We would nail walleye feeding on those red crayfish by jigging orange coloured twister tails off bottom.
Here is one my buddy caught on an orange twister tail with 1/4 oz jighead in 26' of water on the Ottawa. This was our first fish of the evening. We caught and released over 100 in 4 hours that evening.
