Rating depth structure for lake whitefish.

373-acre lake in Sudbury District, Ontario. The lake tops out around 50 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The season-by-season read for each species follows, from the map's own numbers.
Earl Lake maps at 374 acres behind 5.1 miles of shoreline, with a single island in the mix. With a 1.9 development index there's bank structure worth casting at, in moderation. About 33% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 1.3 mi with a 0.8-mi widest point. It sits in Sudbury District. If the bite dies, Indian Lake is 2 mi to the east.
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Summer pushes them deeper, 15 to 50 ft, and winter fish settle into 15 to 50 ft. The spot to know is Deep basin, a deep basin in about 43 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.
| 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 | 15 to 50 ft | dawn | Deep basin (43 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 | 15 to 50 ft | midday & dawn | Deep basin (43 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
