313-acre lake in Algoma District, Ontario. The lake tops out around 202 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 312 acres of water rimmed by 5.8 miles of bank, broken up by an island. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 10% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 1.9 mi of water from one end to the other, 0.7 mi at the beam. The water lies in Algoma District. The nearest mapped water is Caribou Lake, 1 mi to the northwest.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 50 to 120 ft, and winter fish settle into 20 to 80 ft. Break off the point is the standout, a drop-off at roughly 91 ft, rated prime for summer lake trout. Time it for early morning. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (51 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Break off the point (91 ft) | White tube jig (deep), Magnum spoon on downrigger |

In spring, burbot run shallow here, mostly 25 to 70 ft. Summer pushes them deeper, 50 to 120 ft, and winter fish settle into 15 to 60 ft. Break off the point is the standout, a drop-off at roughly 91 ft, rated good for summer burbot. Time it for after dark and midday. You won't need more than a heavy jig + cut bait most summer days.

|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (172 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
