3,102-acre lake in Thunder Bay District, Ontario. The lake tops out around 57 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 3,117 acres wrapped in 45.9 miles of bank, broken up by 16 islands. With a shoreline index of 5.9, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 43% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 6.6 mi end to end and 3.6 mi across at its widest. It sits in Thunder Bay District. Kamikau Lake sits 2 mi east — the closest neighbouring chart.
Spring lake trout on Weikwabinonaw Lake hold shallow, usually 10 to 40 ft. By summer they slide out to 17 to 57 ft, and by winter most fish are in 14 to 57 ft. The chart's best answer is Deep basin — deep basin, 48 ft, prime for summer. Prime time lands in early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
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 (14 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 17 to 57 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (48 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Rock reef (7 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 14 to 57 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (48 ft) | White tube jig, Airplane jig |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 17 to 57 ft, and winter fish settle into 17 to 57 ft. Deep basin is the standout, a deep basin at roughly 48 ft, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 17 to 57 ft, and winter fish settle into 17 to 57 ft. Deep basin is the standout, a deep basin at roughly 48 ft, rated prime for summer cisco (lake herring). Time it for early morning. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.

The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 15 to 35 ft before dropping to 20 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 26 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (7 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (26 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (26 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (26 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (26 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (26 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 6 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Sharp break (12 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
