You were in the right area, maybe just the wrong time. I went out late this afternoon to see if the house my Dad has been using came through the "flood" OK and decided to drop a line when I was there. When I first dropped the hook down the hole a walleye screamed up off the bottom and slammed it 5 feet off the bottom. So out of curiosity I just sat there and jigged 4 to 5 feet off the bottom and they kept coming up and slamming it. They never touched the dead stick that was set 1 foot off the bottom. All I can think of is that with the snow cover gone they could really see something up against the sunlight. I hadn't seen the walleyes that aggressive all winter. maybe it was because I was fishing in a hole about 20 inches wide due to the water running down it.
No I don't think so cuz I have a big roll of duct tape and a bunch of white sheets. I'll wrap me, the Jeep and the dog in white sheets. We'll be just like ghosts. OOPS, just remembered that the snow is all gone. I really think that after all the years we each could stick a pin in a lake map guessing where the other one would be and we would each be within 1/4 mile. From his description fishing tech was right on the eastern edge of your favorite area.
