416-acre lake in Sudbury District, Ontario. The lake tops out around 52 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Species by species, here's what the data says the year looks like.
The drawn water covers 419 acres wrapped in 10.5 miles of bank, broken up by an island. That shoreline is heavily fingered (development index 3.7) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 65% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 2.3 mi with a 1.2-mi widest point. Sudbury District claims this one. If the bite dies, Mackie Lake is 2 mi to the southeast.
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 16 to 52 ft before dropping to 16 to 52 ft for winter. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 44 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (23 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 16 to 52 ft | dawn | Deep basin (44 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (23 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 16 to 52 ft | midday & dawn | Deep basin (44 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 23 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (13 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (23 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (23 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (23 ft) | Jigging spoon + minnow head, Rattle bait |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 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 and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
Spring burbot on Mishap Lake hold shallow, usually 16 to 52 ft. Depth-wise the year is flat: 16 to 52 ft in summer, 13 to 52 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 44 ft that grades prime for spring. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 16 to 52 ft | night & dusk | Deep basin (44 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 16 to 52 ft | night & midday | Deep basin (44 ft) | Heavy jig + cut bait |
| Fall | 16 to 52 ft | night & dusk | Deep basin (44 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 13 to 52 ft | night & dusk | Deep basin (44 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
