405-acre lake in Algoma District, Ontario. The lake tops out around 131 ft. The depth data here comes from the Ontario MNRF survey of 1980 (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 407 acres of water rimmed by 9.9 miles of bank — 7 islands included. An index of 3.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 25% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 1.8 mi end to end and 1.1 mi across at its widest. The water lies in Algoma District. For a second option, Kwagama Lake lies 4 mi northwest.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Spring brook trout concentrate at Main-lake point, a prime-rated point around 1 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
