262-acre lake in Nipissing District, Ontario. The lake tops out around 60 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 1971, a decades-old survey (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
On the chart, Clemow Lake draws 262 acres inside 4.9 miles of shoreline. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 51% of the surface — that's where the groceries are. The basin spans about 1.6 mi end to end and 0.5 mi across at its widest. You'll find it in Nipissing District. For a second option, Greenleaf Lake lies 3 mi southwest.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 18 to 60 ft; cold water stacks them in 15 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 50 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
