On 9/6 we also were out there perching on the fringes of that big pack of boats off lakeside. After a couple hours putting zero perch in the cooler we tried for an hour a few miles off of Perry’s monument until the weather made us pull up the anchor—also zero perch despite a bunch of marks on the fish finder. We slowly motored over to ~2-3 miles off the SE corner of Kelley’s during the downpour and once the rain stopped, we decided to switch gears like you and go after walleye. We did a NNE troll and put 4 nice size eyes in the cooler and lost another right at the boat (with a handful of shorts mixed in but no sheepshead) in a matter of an hour & a half. Was surprised at the grade of fish considering I thought they were all far out east this time of year. The rod pulling a fire red spoon behind a 50TT 75 feet back did most of the catching.
