51-acre lake in Timiskaming District, Ontario. The lake tops out around 41 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 season-by-season read for each species follows, from the map's own numbers.
The outline encloses 52 acres, worked by 2.2 miles of shoreline. With a shoreline index of 2.2, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 56% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.8 mi end to end and 0.3 mi across at its widest. Timiskaming District claims this one. If the bite dies, Beland Lake is 1 mi to the southwest.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 12 to 41 ft in summer and finish the year down in 10 to 41 ft. If you only fish one area, make it Deep basin: a deep basin around 35 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 12 to 41 ft | dawn | Deep basin (35 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 8 to 41 ft | dusk & dawn | Main-lake point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 10 to 41 ft | dawn | Deep basin (35 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: cisco (lake herring) in 10 to 40 ft. Midsummer fish sit out in 12 to 41 ft before dropping to 12 to 41 ft for winter. The spot to know is Deep basin, a deep basin in about 35 ft of water that rates prime for cisco (lake herring) in spring. Plan around early morning in the warm months. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (35 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 12 to 41 ft | dawn | Deep basin (35 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (18 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 12 to 41 ft | dawn | Deep basin (35 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Shallow bay flat, a weed flat in about 5 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (18 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (35 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (35 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. Midsummer fish sit out in 2 to 10 ft before dropping to 6 to 18 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 5 ft of water that rates prime for pumpkinseed in spring. Plan around the evening and early morning in the warm months. Summer baits: a micro tube or a sponge spider (fly) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (5 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (5 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (5 ft) | Tungsten ice jig + plastic, Tiny spoon |
