267-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. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 230 acres, worked by 6.2 miles of shoreline, with 9 islands in the mix. With a shoreline index of 2.9, this water is all arms and coves — edge habitat well beyond its acreage. 21% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 1 mi end to end and 0.6 mi across at its widest. Thunder Bay District claims this one. If the bite dies, O'Meara Lake is 4 mi to the north.
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Main-lake point is the standout, a point at roughly 34 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 | Secondary point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Main-lake point (34 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Main-lake point (34 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Main-lake point (34 ft) | Jigging spoon + minnow head, Rattle bait |
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 6 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 (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Back-bay flat (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
