673-acre lake in Thunder Bay District, Ontario. The lake tops out around 5 ft. The depth data here comes from the Ontario MNRF survey of 1976, a decades-old survey (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 676 acres of water rimmed by 5.6 miles of bank — 3 islands included. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 1.5 mi end to end and 1.3 mi across at its widest. The water lies in Thunder Bay District. The nearest mapped water is West Lacasse Lake, 4 mi to the west.
Early season yellow perch use the shallows, holding in 1 to 5 ft. Even in summer they hold at 2 to 5 ft; winter keeps them in 2 to 5 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 5 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 5 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 5 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 1 to 5 ft. Summer keeps them at 2 to 5 ft, and they winter in 2 to 5 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |

| Fall | 2 to 5 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
