3,273-acre lake in Thunder Bay District, Ontario. The lake tops out around 59 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Species by species, here's what the data says the year looks like.
The outline encloses 3,288 acres, worked by 60 miles of shoreline, broken up by 26 islands. With a shoreline index of 7.5, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 87% of the surface — that's where the groceries are. The basin spans about 9.8 mi end to end and 3.1 mi across at its widest. Thunder Bay District claims this one. If the bite dies, Loganberry Lake is 6 mi to the southeast.
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 18 to 59 ft before dropping to 18 to 59 ft for winter. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 48 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Sharp break (15 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 18 to 59 ft | dawn | Deep basin (48 ft) | Blade bait vertical, Small jigging spoon |

The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Top water on the chart: Sharp break, a drop-off in the 15 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Shoreline point (6 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Sharp break (15 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Sharp break (15 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deepest basin (46 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Weed flat is the standout, a weed flat at roughly 6 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Weed flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |

| Fall | 12 to 35 ft | midday | Sharp break (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Sharp break (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Weed flat first on the milk run — a weed flat near 6 ft that grades prime for spring. In summer the feeding windows fall in 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 | Weed flat (6 ft) | #5 inline spinner, Spoon (red/white) |
