35-acre lake in Algoma District, Ontario. The lake tops out around 20 ft. The depth data here comes from the Ontario MNRF survey of 2004 (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
On the chart, Cub Bear Lake draws 35 acres inside 1.1 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 74% of this chart. Call it 0.4 mi long by 0.2 mi wide at the broadest reach. You'll find it in Algoma District. For a second option, Little White Bear Lake lies 0 mi north.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 3 to 20 ft. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
