82-acre lake in Algoma District, Ontario. The lake tops out around 26 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Supple Lake runs 82 acres with 2.9 miles of edge. A development index of 2.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. 79% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 0.8 mi with a 0.4-mi widest point. The water lies in Algoma District. For a second option, Gervais L. 11 lies 0 mi north.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 8 to 26 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 22 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.
