995-acre lake in Sudbury District, Ontario. The lake tops out around 80 ft. 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.
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.
| 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 | 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.
| 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 | 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) |
