32-acre lake near Kalkaska County. The lake tops out around 15 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Island Lake maps at 33 acres behind 1.3 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. It sits in Kalkaska County. Its nearest charted neighbour, Guernsey Lake, is 2 mi to the southwest.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. They don't go far with the seasons — 5 to 15 ft covers summer, 5 to 15 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 5 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 15 ft | dusk & dawn | Break off the point (5 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 15 ft | dusk & night | Break off the point (5 ft) | Jigging rap, Jig + big minnow |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 5 to 15 ft; cold water stacks them in 5 to 15 ft. Deep basin is the standout, a deep basin at roughly 15 ft, rated prime for fall yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
