202-acre lake in Sudbury District, Ontario. The lake tops out around 53 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What the data behind the map says about each species, season by season:
The drawn water covers 204 acres wrapped in 7.9 miles of bank, broken up by 2 islands. An index of 3.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 74% of the surface on the model — that's where the groceries are. The basin spans about 2.4 mi end to end and 0.5 mi across at its widest. Sudbury District claims this one. If the bite dies, View Lake is 1 mi to the east.
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 16 to 53 ft before dropping to 16 to 53 ft for winter. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 45 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 (24 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 16 to 53 ft | dawn | Deep basin (45 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (24 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 16 to 53 ft | midday & dawn | Deep basin (45 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
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 |
