244-acre lake in Algoma District, Ontario. The lake tops out around 70 ft. The depth data here comes from the Ontario MNRF survey of 1972, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 246 acres wrapped in 4.9 miles of bank. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 39% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 1.9 mi end to end and 0.5 mi across at its widest. It sits in Algoma District. If the bite dies, Fish Lake is 1 mi to the southeast.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Back-bay flat is the standout, a weed flat at roughly 7 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
