372-acre lake in Kenora 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 the Ontario MNRF survey of 1974, a decades-old survey (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 375 acres of water rimmed by 5.2 miles of bank. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. Roughly 55% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 1.6 mi with a 0.8-mi widest point. You'll find it in Kenora District. The nearest mapped water is Grey Trout Lake, 2 mi to the southwest.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 24 to 80 ft before dropping to 20 to 80 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 70 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
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 | Break off the point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 24 to 80 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (70 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (70 ft) | White tube jig, Airplane jig |
Spring lake whitefish on Little Grey Trout Lake hold shallow, usually 15 to 45 ft. They move out to 24 to 80 ft in summer and finish the year down in 25 to 70 ft. Put Deep basin first on the milk run — a deep basin near 70 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (10 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 24 to 80 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (70 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (10 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (70 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Break off the point. It's a drop-off holding about 10 ft of water and rates prime come summer. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| 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 | Break off the point (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
