115-acre lake in Nipissing District, Ontario. The lake tops out around 98 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Lost Dog Lake runs 116 acres with 2.5 miles of edge. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. 7% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 0.7 mi of water from one end to the other, 0.5 mi at the beam. The water lies in Nipissing District. Closest neighbour on DepthScout: Sisco Lake, 1 mi northeast of here.
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 Secondary point, a prime-rated point around 13 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.

A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
