1,516-acre lake in Thunder Bay District, Ontario. The lake tops out around 40 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 1,523 acres, worked by 19 miles of shoreline, with 12 islands in the mix. An index of 3.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 34% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 3.4 mi, about 1.8 mi across. Thunder Bay District claims this one. If the bite dies, Blunder Lake is 4 mi to the west.
Start shallow in spring: lake whitefish sit in 12 to 40 ft that time of year. They don't go far with the seasons — 12 to 40 ft covers summer, 12 to 40 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 40 ft range, prime in summer. Fish it in early morning and you'll meet the bite. 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 | 12 to 40 ft | midday & dawn | Break off the point (21 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 12 to 40 ft | dawn | Deep basin (40 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (21 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 12 to 40 ft | midday & dawn | Deep basin (40 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. They don't go far with the seasons — 12 to 40 ft covers summer, 12 to 40 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 40 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (40 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 12 to 40 ft | dawn | Deep basin (40 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (21 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 12 to 40 ft | dawn | Deep basin (40 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Break off the point is the standout, a drop-off at roughly 21 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (21 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (21 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (40 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 21 ft range, prime in summer. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| 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 (21 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (21 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (40 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. In summer the feeding windows fall in 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 | Shallow feeding flat (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (21 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 |
When the water first warms, burbot slide up into 12 to 40 ft. There's no big seasonal slide here — summer means 12 to 40 ft, winter 10 to 40 ft. Start at Deep basin. It's a deep basin holding about 40 ft of water and rates prime come spring. The feeding windows run after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 12 to 40 ft | night & dusk | Deep basin (40 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
