592-acre lake in Thunder Bay District, Ontario. The lake tops out around 70 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 594 acres, worked by 7.4 miles of shoreline, broken up by 4 islands. A development index of 2.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 31% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1.8 mi long by 1.1 mi wide at the broadest reach. It sits in Thunder Bay District. Harp Lake sits 2 mi west — the closest neighbouring chart.
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 21 to 70 ft, and winter fish settle into 25 to 70 ft. Deep basin is the standout, a deep basin at roughly 70 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.

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, 13 ft, prime for winter. 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 | Back-bay flat (10 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (13 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
