72-acre lake near Montmorency 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. Species by species, here's what the data says the year looks like.
The chart traces 1.7 miles of shoreline here. With a 1.8 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 98% of the surface — that's where the groceries are. Call it 0.5 mi long by 0.4 mi wide at the broadest reach. It sits in Montmorency County. If the bite dies, Rush Lake is 2 mi to the northwest.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 6 to 19 ft before dropping to 6 to 19 ft for winter. The spot to know is Deep basin, a deep basin in about 17 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. 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 (2 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 |
| Winter | 6 to 19 ft | midday & dawn | Deep basin (17 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. Summer is a 6 to 19 ft game here, winter a 6 to 19 ft one. Start at Break off the point. It's a drop-off holding about 7 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Secondary point (3 ft) | Ned rig, Tube jig |
| Summer | 6 to 19 ft | dawn & dusk | Break off the point (7 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 19 ft | midday & dawn | Break off the point (7 ft) | Jerkbait, Blade bait |
| Winter | 6 to 19 ft | midday | Break off the point (7 ft) | Blade bait, Hair jig |
Start shallow in spring: rock bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 5 to 19 ft, and winter fish settle into 6 to 19 ft. The spot to know is Break off the point, a drop-off in about 7 ft of water that rates prime for rock bass in fall. Warm-month bites cluster around the evening. 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 (2 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 19 ft | dusk | Break off the point (7 ft) | Ned rig (small), Marabou jig |
| Fall | 6 to 19 ft | midday | Break off the point (7 ft) | Small tube jig, Inline spinner |
| Winter | 6 to 19 ft | midday | Deep basin (17 ft) | Tungsten jig + plastic, Small spoon + spike |
