291-acre lake in Thunder Bay District, Ontario. The lake tops out around 30 ft. The depth data here comes from the Ontario MNRF survey of 2003 (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 292 acres wrapped in 12.5 miles of bank. With a shoreline index of 5.2, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 85% of this chart. Tip to tip the water measures near 2.9 mi with a 1.3-mi widest point. It sits in Thunder Bay District. If the bite dies, Loch Lomond is 6 mi to the south.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 25 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (25 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (3 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 8 to 30 ft. There's no big seasonal slide here — summer means 9 to 30 ft, winter 8 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 25 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 30 ft | dawn & dusk | Main-lake point (5 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 9 to 30 ft | dawn | Deep basin (25 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 6 to 30 ft | dusk & dawn | Main-lake point (5 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 8 to 30 ft | dawn | Deep basin (25 ft) | White tube jig, Airplane jig |
Come spring, look for chinook salmon tight to the bank in 4 to 30 ft. Through summer count on 9 to 30 ft; the winter hold is 9 to 30 ft. Start at Deep basin. It's a deep basin holding about 25 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A flasher + fly (green/white) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 30 ft | dawn & dusk | Break off the point (3 ft) | Trolled spoon (orange/gold), Stickbait off planer boards |
| Summer | 9 to 30 ft | dawn & dusk | Deep basin (25 ft) | Flasher + fly (green/white), Magnum spoon on downrigger |
| Fall | 6 to 30 ft | dawn & dusk | Main-lake point (5 ft) | J-plug (glow), Flasher + fly |
| Winter | 9 to 30 ft | midday | Deep basin (25 ft) | Small spoon on a slow troll, Stickbait deep |
Come spring, look for coho salmon tight to the bank in 3 to 25 ft. They move out to 9 to 30 ft in summer and finish the year down in 9 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 25 ft that scores prime in summer. Best bite is early morning and the evening. A dodger + fly or a medium spoon above the thermocline is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (5 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 9 to 30 ft | dawn & dusk | Deep basin (25 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 6 to 30 ft | dawn & dusk | Main-lake point (5 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 9 to 30 ft | midday | Deep basin (25 ft) | Small spoon, slow troll |
Start shallow in spring: lake whitefish sit in 9 to 30 ft that time of year. They don't go far with the seasons — 9 to 30 ft covers summer, 9 to 30 ft covers winter. The spot to know is Deep basin, a deep basin in about 25 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 | 9 to 30 ft | midday & dawn | Break off the point (3 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 9 to 30 ft | dawn | Deep basin (25 ft) | Blade bait vertical, Small jigging spoon |

| Winter | 9 to 30 ft | midday & dawn | Deep basin (25 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: cisco (lake herring) sit in 8 to 30 ft that time of year. They don't go far with the seasons — 9 to 30 ft covers summer, 9 to 30 ft covers winter. The spot to know is Deep basin, a deep basin in about 25 ft of water that rates prime for cisco (lake herring) in spring. Warm-month bites cluster around early morning. 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 | 8 to 30 ft | dawn & dusk | Deep basin (25 ft) | Small silver spoon, Tiny swim jig (white) |
