Horseshoe Lake maps at 596 acres behind 9.1 miles of shoreline, with a single island in the mix. With a shoreline index of 2.7, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 81% of the water is 15 ft or less as modeled, the band where the food chain lives.

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 7 to 24 ft before dropping to 7 to 24 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
