995-acre lake in Sudbury District, Ontario. The lake tops out around 80 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 a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
On the chart, David Lake draws 999 acres inside 24.4 miles of shoreline, broken up by 29 islands. With a shoreline index of 5.5, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 35% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 3.1 mi end to end and 1.9 mi across at its widest. The water lies in Sudbury District. For a second option, Boundary Lake lies 1 mi southwest.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 24 to 80 ft, wintering in 20 to 80 ft. Top water on the chart: Deep basin, a deep basin in the 80 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger 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 | 10 to 40 ft | dawn & dusk | Main-lake point (11 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 24 to 80 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (80 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (11 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (80 ft) | White tube jig, Airplane jig |
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. Expect a summer slide to 24 to 80 ft, then a winter hold in 25 to 70 ft. Start at Deep basin. It's a deep basin holding about 80 ft of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
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 | 15 to 45 ft | midday & dawn | Break off the point (20 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 24 to 80 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (80 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (20 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (80 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 8 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 10 to 25 ft. The spot to know is Shallow bay flat, a weed flat in about 8 ft of water that rates prime for brown bullhead in spring. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (8 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (8 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (8 ft) | |
| Winter | 10 to 25 ft | midday | open water |
