59-acre lake in Timiskaming District, Ontario. The lake tops out around 46 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 59 acres of water rimmed by 2.7 miles of bank. The 2.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Roughly 60% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.6 mi end to end and 0.5 mi across at its widest. The water lies in Timiskaming District. The nearest mapped water is Bergeron Lake, 1 mi to the east.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Break off the point, a drop-off in about 21 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (12 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (21 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (12 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (21 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. Expect a summer slide to 14 to 46 ft, then a winter hold in 14 to 46 ft. Start at Deep basin. It's a deep basin holding about 39 ft of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (21 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 14 to 46 ft | dawn | Deep basin (39 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (21 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 14 to 46 ft | midday & dawn | Deep basin (39 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. Expect a summer slide to 14 to 46 ft, then a winter hold in 14 to 46 ft. Start at Deep basin. It's a deep basin holding about 39 ft of water and rates prime come spring. Prime time lands in early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (39 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 14 to 46 ft | dawn | Deep basin (39 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (21 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 14 to 46 ft | dawn | Deep basin (39 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (21 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (21 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (39 ft) | Tungsten jig + spikes, Rattle spoon (small) |
