922-acre lake in Nipissing District, Ontario. The lake tops out around 76 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 923 acres of water rimmed by 11.8 miles of bank. With a shoreline index of 2.8, this water is all arms and coves — edge habitat well beyond its acreage. 36% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 3.5 mi with a 1.5-mi widest point. You'll find it in Nipissing District. The nearest mapped water is Laurel Lake, 3 mi to the north.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated good for spring brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (34 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (19 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 23 to 76 ft; cold water stacks them in 19 to 76 ft. Deep basin is the standout, a deep basin at roughly 65 ft, rated prime for summer lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 23 to 76 ft | dawn | Deep basin (65 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (19 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 19 to 76 ft | dawn | Deep basin (65 ft) | White tube jig, Airplane jig |
Early season cisco (lake herring) use the shallows, holding in 10 to 40 ft. Summer is a 23 to 76 ft game here, winter a 20 to 60 ft one. The chart's best answer is Deep basin — deep basin, 65 ft, prime for summer. Best bite is early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (34 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 23 to 76 ft | dawn | Deep basin (65 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (65 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring puts burbot in skinny water — 25 to 70 ft is the zone. Warm water sends them out to 23 to 76 ft; cold water stacks them in 15 to 60 ft. Deep basin is the standout, a deep basin at roughly 65 ft, rated prime for spring burbot. Plan around after dark and midday in the warm months. A heavy jig + cut bait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (65 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 23 to 76 ft | night & midday | Deep basin (65 ft) | Heavy jig + cut bait |
| Fall | 23 to 76 ft | night & dusk | Deep basin (65 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (65 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
