63-acre lake in Timiskaming District, Ontario. The lake tops out around 27 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Species by species, here's what the data says the year looks like.
The drawn water covers 63 acres wrapped in 1.9 miles of bank. A middling shoreline index (1.7) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 59% of the surface on the model — that's where the groceries are. End to end it runs roughly 0.7 mi, about 0.3 mi across. It sits in Timiskaming District. If the bite dies, Maurice L. is 1 mi to the east.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 8 to 27 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 23 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 27 ft | dawn & dusk | Deep basin (23 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (12 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 7 to 27 ft, then a winter hold in 5 to 27 ft. Start at Break off the point. It's a drop-off holding about 12 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 7 to 27 ft | dawn & dusk | Break off the point (12 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 8 to 27 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 27 ft | dawn | Break off the point (12 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 23 ft.
