My shore experience with walleye has been limited to the Erie Canal, where the water is very murky green and maximum depth is ~10'. They readily take grubs on jigheads, but I've used crankbaits much more. They've taken a wide variety of cranks in various brands, sizes, shapes and colors. Some of the baits I use more than others are #5 Shad Raps, Bomber 6A, Deep Baby N, Deep Flat A and others.
Sundown is probably a good time, as they're reputed to be light-sensitive. However, that hasn't affected me because the water is so murky. However, other guys have told me that it's much harder to catch them during the day further downstream where the water is clearer.
Good luck. Walleyes can be good fighters, not acrobatic, but strong, consistently pulling toward the bottom.
