162-acre lake near Van Buren County. The lake tops out around 20 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 203 acres wrapped in 2.3 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. About 89% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.8 mi of water from one end to the other, 0.7 mi at the beam. It sits in Van Buren County. If the bite dies, Cable Lake is 1 mi to the southeast.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 6 to 20 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
