There is much to be said about that, but then again the underwater structure doesn't usually change much. Once you find a Walleye hole and figure out how to fish it, getting a limit is pretty easy to do.
There is a lake in Minnesota, just north of Duluth that I went fishing with my dad and uncles from the time I was about 8 until I shipped off to basic training at 17. They had been fishing this lake for many years and knew where each and every Walleye or Northern was hiding. Years later when on leave went back up there on my own along with a few friends. The locals said the fish weren't biting and were not bothering to go out. We went out in a rented boat with one of my old Johnson outboards and came back in several hours later each with a limit of Walleyes and several 30 inch plus Northern Pike (I like the Northerns, good eating as long as careful about Y bones) and the locals couldn't believe it. Which reminds me about a quip about fishing. There is a reason it's called
Fishing, and not
Catching.
One of those is that you are not going to catch fish by sitting in a bar. Winneconne is possibly the only exception to that rule. You can sit at the bar and watch your rods while having a Brewski or two, or sit out on the patio. There is a service window going to the bar behind you where said Brewskis can pass to you out on the patio.
