54-acre lake in Nipissing District, Ontario. The lake tops out around 40 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1968, a decades-old survey (an MNRF lake survey). The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Side Rock Lake runs 55 acres with 2.1 miles of edge. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 76% of the water is 15 ft or less, the band where the food chain lives. Call it 0.9 mi long by 0.2 mi wide at the broadest reach. The water lies in Nipissing District. Closest neighbour on DepthScout: Malloch Lake, 0 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 30 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.
