159-acre lake in Algoma District, Ontario. The lake tops out around 66 ft. The depth data here comes from the Ontario MNRF survey of 1978, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
The drawn water covers 159 acres wrapped in 4.4 miles of bank. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. 44% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 1.3 mi with a 0.5-mi widest point. Algoma District claims this one. If the bite dies, Pebble Lake is 1 mi to the southeast.
Spring brook trout on Claim Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (39 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (7 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, splake slide up into 5 to 25 ft. Summer is a 25 to 60 ft game here, winter a 10 to 45 ft one. Start at Break off the point. It's a drop-off holding about 39 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a trolled spoon at the thermocline or a white tube jig (deep) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (39 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Secondary point (13 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (39 ft) | Jigging spoon tipped with minnow head, Small white tube |
The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. Midsummer fish sit out in 2 to 10 ft before dropping to 6 to 18 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 7 ft of water that rates prime for pumpkinseed in spring. Plan around the evening and early morning in the warm months. Summer baits: a micro tube or a sponge spider (fly) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (7 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (7 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (7 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (7 ft) | Tungsten ice jig + plastic, Tiny spoon |
