120-acre lake in Algoma District, Ontario. The lake tops out around 17 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (an MNRF lake survey). The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Prince Lake draws 120 acres inside 2 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. Tip to tip the water measures near 0.6 mi with a 0.4-mi widest point. You'll find it in Algoma District. For a second option, Monocle Lake lies 7 mi southwest.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 5 to 17 ft, and winter fish settle into 3 to 17 ft. The spot to know is Deep basin, a deep basin in about 10 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 17 ft | dawn & dusk | Deep basin (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 17 ft | dawn | Deep basin (10 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 5 to 17 ft; cold water stacks them in 5 to 17 ft. Main-lake point is the standout, a point at roughly 1 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 5 to 17 ft | dawn & dusk | Break off the point (1 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 17 ft | midday & dawn | Main-lake point (1 ft) | Jerkbait, Blade bait |
| Winter | 5 to 17 ft | midday | Break off the point (1 ft) | Blade bait, Hair jig |
When the water first warms, rock bass slide up into 2 to 10 ft. Summer is a 4 to 17 ft game here, winter a 5 to 17 ft one. Start at Deep basin. It's a deep basin holding about 10 ft of water and rates prime come winter. The feeding windows run the evening. Keep a ned rig (small) or a marabou jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (1 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 4 to 17 ft | dusk | Main-lake point (1 ft) | Ned rig (small), Marabou jig |
| Fall | 5 to 17 ft | midday | Break off the point (1 ft) | Small tube jig, Inline spinner |
| Winter | 5 to 17 ft | midday | Deep basin (10 ft) | Tungsten jig + plastic, Small spoon + spike |
The spring pattern is a shallow one: brown bullhead in 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 5 to 17 ft for winter. The spot to know is Deep basin, a deep basin in about 10 ft of water that rates prime for brown bullhead in winter. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (1 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (1 ft) | |
| Fall | 5 to 15 ft | dusk | Deep basin (10 ft) | |
| Winter | 5 to 17 ft | midday | Deep basin (10 ft) |
