Rating depth structure for yellow perch.

107-acre lake near Montmorency County. The lake tops out around 55 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
The outline encloses 94 acres, worked by 1.8 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. About 20% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.6 mi end to end and 0.4 mi across at its widest. Montmorency County claims this one. If the bite dies, Crooked Lake is 2 mi to the southeast.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 8 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (33 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (33 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (33 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: rock bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 20 ft; cold water stacks them in 12 to 30 ft. Top water on the chart: Secondary point, a point in the 14 ft range, prime in summer. Fish it in the evening and you'll meet the bite. Throw a ned rig (small) or a marabou jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (3 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Secondary point (14 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Secondary point (14 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Break off the point (33 ft) | Tungsten jig + plastic, Small spoon + spike |
