69-acre lake in Simcoe County, Ontario. The lake tops out around 16 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Otter Lake draws 68 acres inside 2.1 miles of shoreline. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. The shallow band under 15 ft claims about 94% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 0.8 mi with a 0.3-mi widest point. The water lies in Simcoe County. For a second option, MacLean Lake lies 1 mi northwest.
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 5 to 16 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| 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 |

The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. As the season builds they drop to 5 to 16 ft, wintering in 5 to 16 ft. Top water on the chart: Main-lake point, a point in the 8 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |

Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
