5,625-acre lake in Thunder Bay District, Ontario. The lake tops out around 39 ft. The depth data here comes from the Ontario MNRF survey of 1978, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 5,651 acres wrapped in 79.4 miles of bank, with 59 islands in the mix. That shoreline is heavily fingered (development index 7.5) — bays, points and pockets everywhere, which multiplies the fishable edge. About 58% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 9 mi end to end and 5.7 mi across at its widest. It sits in Thunder Bay District. Its nearest charted neighbour, Edar Lake, is 6 mi to the south.
The spring pattern is a shallow one: lake whitefish in 12 to 39 ft. The depth story barely changes: 12 to 39 ft through summer, 12 to 39 ft in winter. Top water on the chart: Deep basin, a deep basin in the 38 ft range, prime in summer. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 12 to 39 ft | midday & dawn | Sharp break (23 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 12 to 39 ft | dawn | Deep basin (38 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (4 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 12 to 39 ft | midday & dawn | Deep basin (38 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: cisco (lake herring) in 10 to 39 ft. The depth story barely changes: 12 to 39 ft through summer, 12 to 39 ft in winter. Top water on the chart: Deep basin, a deep basin in the 38 ft range, prime in spring. Time it for early morning. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 39 ft | dawn & dusk | Deep basin (38 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 12 to 39 ft | dawn | Deep basin (38 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Rock reef (4 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 12 to 39 ft | dawn | Deep basin (38 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 15 to 35 ft; cold water stacks them in 12 to 39 ft. Sharp break is the standout, a drop-off at roughly 23 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Sharp break (23 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 39 ft | dusk & night | Sharp break (23 ft) | Jigging rap, Jig + big minnow |
| Winter | 12 to 39 ft | dusk & dawn | Deep basin (38 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Weed flat, a weed flat in the 5 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Weed flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Sharp break (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Sharp break (23 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (38 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Weed flat: a weed flat around 5 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Weed flat (5 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Sharp break (16 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Sharp break (16 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Weed flat (5 ft) | Tip-ups, Large jigging spoon |
Come spring, look for burbot tight to the bank in 12 to 39 ft. Through summer count on 12 to 39 ft; the winter hold is 10 to 39 ft. Start at Deep basin. It's a deep basin holding about 38 ft of water and rates prime come spring. Prime time lands in after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 12 to 39 ft | night & dusk | Deep basin (38 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 12 to 39 ft | night & midday | Deep basin (38 ft) | Heavy jig + cut bait |
| Fall | 12 to 39 ft | night & dusk | Deep basin (38 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 10 to 39 ft | night & dusk | Deep basin (38 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
