433-acre lake in Algoma District, Ontario. The lake tops out around 120 ft. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 435 acres of water rimmed by 5.9 miles of bank, with a single island in the mix. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. 34% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 1.5 mi of water from one end to the other, 1.1 mi at the beam. The water lies in Algoma District. For a second option, Magrath Lake lies 3 mi south.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Secondary point is the standout, a point at roughly 12 ft, rated prime for spring brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
