221-acre lake in Sudbury District, Ontario. The lake tops out around 33 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 1980 (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 222 acres wrapped in 4.6 miles of bank, with a single island in the mix. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 1.1 mi of water from one end to the other, 0.8 mi at the beam. It sits in Sudbury District. Its nearest charted neighbour, Londonderry Lake, is 3 mi to the northeast.
Start shallow in spring: lake whitefish sit in 10 to 33 ft that time of year. They don't go far with the seasons — 10 to 33 ft covers summer, 10 to 33 ft covers winter. The spot to know is Deep basin, a deep basin in about 15 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 33 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (1 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 10 to 33 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (15 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (1 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 10 to 33 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (15 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 10 to 33 ft for winter. The spot to know is Deep basin, a deep basin in about 15 ft of water that rates prime for yellow perch in fall. 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| 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 | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates good come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| 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 | open water | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Deep basin (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
