20-acre lake in Timiskaming District, Ontario. The lake tops out around 20 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. What the data behind the map says about each species, season by season:
Traced from the shoreline, Thin Lake runs 20 acres with 2.1 miles of edge. The 3.3 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 91% of this chart, as modeled. Figure 0.6 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Timiskaming District. Closest neighbour on DepthScout: Tud Lake, 1 mi southwest of here.
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 17 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.
