15-acre lake in Ontario. The lake tops out around 24 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 14 acres of water rimmed by 0.9 miles of bank. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. 78% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. You'll find it in Greater Sudbury / Grand Sudbury. For a second option, Morgan L. 42 lies 2 mi northeast.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 7 to 24 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.
