52-acre lake in Timiskaming District, Ontario. The lake tops out around 16 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 53 acres, worked by 1.9 miles of shoreline. With a 1.9 development index there's bank structure worth casting at, in moderation. Roughly 98% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 0.6 mi, about 0.4 mi across. It sits in Timiskaming District. Its nearest charted neighbour, Mowat Lake, is 1 mi to the northwest.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 5 to 16 ft, then a winter hold in 2 to 16 ft. Put Deep basin first on the milk run — a deep basin near 14 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| 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 | 5 to 16 ft | dawn & dusk | Deep basin (14 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 | 2 to 16 ft | dawn | Deep basin (14 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring rainbow trout on Belle Isle Lake hold shallow, usually 4 to 16 ft. Depth-wise the year is flat: 4 to 16 ft in summer, 3 to 16 ft once it turns cold. The chart's best answer is Break off the point — drop-off, 7 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 16 ft | dawn & dusk | Break off the point (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 16 ft | dawn | Break off the point (7 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 5 to 16 ft before dropping to 5 to 16 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 16 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
