89-acre lake in Algoma District, Ontario. The lake tops out around 72 ft. The depth data here comes from the Ontario MNRF survey of 1988 (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 89 acres of water rimmed by 3 miles of bank, with 2 islands in the mix. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 45% of this chart. The basin spans about 0.8 mi end to end and 0.4 mi across at its widest. You'll find it in Algoma District. The nearest mapped water is Applesauce Lake, 1 mi to the west.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 25 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |

In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 22 to 72 ft before dropping to 18 to 72 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 72 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
