80-acre lake in Haliburton County, Ontario. The lake tops out around 45 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 81 acres of water rimmed by 1.9 miles of bank. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. Roughly 52% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.7 mi end to end and 0.3 mi across at its widest. You'll find it in Haliburton County. The nearest mapped water is Rence Lake, 1 mi to the south.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 20 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
