1,569-acre lake in Thunder Bay District, Ontario. The lake tops out around 20 ft. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 1,577 acres, worked by 8.1 miles of shoreline, with a single island in the mix. With a 1.5 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 67% of this chart. Figure 2.2 mi of water from one end to the other, 1.8 mi at the beam. Thunder Bay District claims this one. Hornick Lake sits 5 mi west — the closest neighbouring chart.
Start shallow in spring: lake whitefish sit in 6 to 20 ft that time of year. They don't go far with the seasons — 6 to 20 ft covers summer, 6 to 20 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 20 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 | 6 to 20 ft | midday & dawn | Break off the point (20 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 5 to 20 ft | dusk | Break off the point (20 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. Break off the point is the standout, a drop-off at roughly 20 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 (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 20 ft | dusk & dawn | Break off the point (20 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft | dusk & night | Break off the point (20 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft | dusk & dawn | Deep basin (20 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 6 to 20 ft, wintering in 6 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. 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 (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 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 3 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 (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow feeding flat (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow feeding flat (10 ft) | Tip-ups, Large jigging spoon |
