141-acre lake in Nipissing District, Ontario. The lake tops out around 40 ft. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 142 acres of water rimmed by 3.6 miles of bank — 2 islands included. A development index of 2.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 49% of the water is 15 ft or less, the band where the food chain lives. Call it 1.2 mi long by 0.3 mi wide at the broadest reach. The water lies in Nipissing District. Closest neighbour on DepthScout: Marten Lake, 3 mi northwest 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 18 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.
