110-acre lake in Sudbury District, Ontario. The lake tops out around 39 ft. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 111 acres of water rimmed by 4 miles of bank, with 2 islands in the mix. The 2.7 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 88% of this chart. Call it 1.1 mi long by 0.6 mi wide at the broadest reach. The water lies in Sudbury District. Closest neighbour on DepthScout: Solski L. 35, 1 mi east of here.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Break off the point, a drop-off in the 11 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
