20-acre lake near Missaukee County. The lake tops out around 19 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Loon Lake runs 20 acres with 1 miles of edge. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 95% of this chart. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. You'll find it in Missaukee County. For a second option, Dyer Lake lies 7 mi southwest.
Spring yellow perch on Loon Lake hold shallow, usually 3 to 12 ft. They move out to 6 to 19 ft in summer and finish the year down in 6 to 19 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 19 ft | dawn | Deep basin (17 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 19 ft | midday | Deep basin (17 ft) | Jigging spoon (small), Perch rig / spreader |

Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 6 to 19 ft; cold water stacks them in 6 to 19 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for fall smallmouth bass. Plan around early morning and the evening in the warm months. A drop shot (goby/minnow) or a ned rig covers the summer program.

|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |

You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
