251-acre lake in Timiskaming District, Ontario. The lake tops out around 70 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. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 250 acres wrapped in 3 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. 34% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 1 mi, about 0.7 mi across. It sits in Timiskaming District. If the bite dies, Bidgood Pothole is 1 mi to the northeast.
Early season splake use the shallows, holding in 5 to 25 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 10 to 45 ft. Put Break off the point first on the milk run — a drop-off near 15 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a trolled spoon at the thermocline or a white tube jig (deep) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (11 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (15 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (11 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (15 ft) | Jigging spoon tipped with minnow head, Small white tube |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 21 to 70 ft, and winter fish settle into 25 to 70 ft. Deep basin is the standout, a deep basin at roughly 70 ft, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (15 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 21 to 70 ft | dawn | Deep basin (70 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (15 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (70 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 21 to 70 ft, and winter fish settle into 20 to 60 ft. Deep basin is the standout, a deep basin at roughly 70 ft, rated prime for summer cisco (lake herring). Time it for early morning. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (15 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 21 to 70 ft | dawn | Deep basin (70 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (15 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (70 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. Summer yellow perch concentrate at Break off the point, a prime-rated drop-off around 15 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
