183-acre lake in Nipissing District, Ontario. The lake tops out around 180 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 183 acres wrapped in 4 miles of bank. With a 2.1 development index there's bank structure worth casting at, in moderation. Roughly 13% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 1.5 mi, about 0.4 mi across. It sits in Nipissing District. Its nearest charted neighbour, Cut Lake, is 1 mi to the northeast.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Shallow bay flat first on the milk run — a feeding flat near 6 ft that grades good for spring. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| 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 | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 50 to 120 ft, and by winter most fish are in 20 to 80 ft. If you only fish one area, make it Break off the point: a drop-off around 81 ft that scores prime in winter. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (45 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Break off the point (81 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (45 ft) | Heavy casting spoon, Jigging rap over reefs |
