28-acre lake in Algoma District, Ontario. The lake tops out around 56 ft. The depth data here comes from the Ontario MNRF survey of 2025 (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 28 acres of water rimmed by 1.1 miles of bank. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 23% of the surface — that's where the groceries are. Tip to tip the water measures near 0.3 mi with a 0.3-mi widest point. The water lies in Algoma District. Closest neighbour on DepthScout: Rheaume Lake, 2 mi southeast of here.
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 6 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.
