186-acre lake in Timiskaming District, Ontario. The lake tops out around 95 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. The depth data here comes from the Ontario MNRF survey of 1967, a decades-old survey (an MNRF lake survey). Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 186 acres, worked by 3.9 miles of shoreline. With a 2 development index there's bank structure worth casting at, in moderation. About 74% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1.3 mi with a 0.4-mi widest point. Timiskaming District claims this one. If the bite dies, Scott Lakes is 4 mi to the southeast.
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. Midsummer fish sit out in 40 to 90 ft before dropping to 25 to 70 ft for winter. The spot to know is Deep basin, a deep basin in about 90 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (6 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Deep basin (90 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (6 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (90 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: cisco (lake herring) in 10 to 40 ft. Midsummer fish sit out in 40 to 80 ft before dropping to 20 to 60 ft for winter. The spot to know is Deep basin, a deep basin in about 90 ft of water that rates prime for cisco (lake herring) in summer. 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 (90 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (90 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (6 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (90 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 1 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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (6 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (90 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Break off the point. It's a drop-off holding about 6 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (6 ft) | Tip-ups, Large jigging spoon |
