Why would you need to wade out in the water ?. The walleye will move up shallow enough that you can cast to them. Best to try it after dark. They often move up to 1' or 2' deep.
This time of year, early morning or late evening, cast along the rip rap with a slow retrieve. Small shallow diving crankbaits are the ticket.
Like the Kid said, fish the wind blown shore, bundle up, that wind off the water is very cold.
I was out in the boat 3:00 am easter morning. Used my spot light, seen several glowing eyes right up against the shore line.
I didn't catch anything. I had a bad headache so I only fished one hour, then left.
