244-acre lake in Algoma District, Ontario. The lake tops out around 60 ft. The depth data here comes from the Ontario MNRF survey of 1965, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
On the chart, Peak Lake draws 245 acres inside 5.5 miles of shoreline, with a single island in the mix. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 24% of the water is 15 ft or less, the band where the food chain lives. Call it 1.5 mi long by 0.7 mi wide at the broadest reach. The water lies in Algoma District. The nearest mapped water is Emerald Lake, 2 mi to the southwest.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 18 to 60 ft, and winter fish settle into 15 to 60 ft. Deep basin is the standout, a deep basin at roughly 60 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.
