In the spring I tend to vertical jig, fish 3-ways with cranks, floating jig head/minnow or plastic or flies or pitch ring worms rather than pull lead for no other reason than growing up fishing Dubuque, Prairie du Chien, Lynxville and Genoa, that’s what we did. Old habits are hard to break. Incidentally, back then we always called pulling 3-ways “draggin'” and the technique now widely known as “draggin'” was simply drifting jigs -even though we were under power and really weren’t drifting.
In May thru mid-June I spend a lot of time in 3′-5′ pulling Flicker Shads 10′ to 20′ back behind planer boards. It seems like I always have to cover significant stretches of shoreline to find them but when you do there is typically a bunch of very aggressive fish. When they get spooky from being run over too many times I go back through and pick off more either draggin’ with Gulp, casting cranks or pitching jigs/plastics depending on the location. Once you find them you can usually look for similar places elsewhere on the lake and like magic, fish are there too. When that bite either doesn’t develop (or I can’t find them) Slow Death rigs usually work deeper.
I feel as though bright sunny days kick-start the food chain on Lake Wisconsin and some walleyes tend to move very shallow to feed. When the algae blooms I believe you can throw all of the preconceived notions about walleyes and light sensitivity out the window. I think Lake Wisconsin’s dark water + significant algae bloom = welding goggle type visibility allowing them to roam super shallow in relative comfort. I also believe because of this the lures with UV paint finishes will continue to excel under these conditions.
I have found a pretty good summer-time lead core bite that lasts for about a week in 15′-20′ during a period loosely defined as some time from the last week of June through the middle of July. Annually the majority of big fish in my boat come during this period and from this tactic. 2012 was the exception, perhaps due to the drought. I need to pay more attention to the mayfly hatches and see if this plays a role in when this bite takes place. I know I don’t get them during a hatch but am curious if they stage there prior to or after.
However, in late August 2012 fishing in the same area as I usually do pulling lead, but instead using the technique described by Boog for suspended walleyes, my nephew popped an 8lber + more to take home for supper. That day sticks out in my memory as that big fish ate a shad rap just as John Schultz was cruising by in his new rig.
