475-acre lake in Thunder Bay District, Ontario. The lake tops out around 35 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1972, a decades-old survey (an MNRF lake survey). Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 478 acres, worked by 9.2 miles of shoreline. That shoreline is heavily fingered (development index 3) — bays, points and pockets everywhere, which multiplies the fishable edge. 98% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 2.2 mi end to end and 1.2 mi across at its widest. It sits in Thunder Bay District. Its nearest charted neighbour, Mosher Lake, is 5 mi to the northeast.
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 11 to 35 ft for winter. The spot to know is Deep basin, a deep basin in about 29 ft of water that rates prime for walleye in winter. 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.
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 | 4 to 15 ft | dusk & dawn | Break off the point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Deep basin (29 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 11 to 35 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (29 ft) | Jigging rap, Jig + big minnow |
| Winter | 11 to 35 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (29 ft) | Jigging spoon + minnow head, Rattle bait |
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, 1 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 (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (18 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow feeding flat (18 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
