37-acre lake in Nipissing District, Ontario. The lake tops out around 21 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 37 acres of water rimmed by 1.2 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 51% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 0.5 mi, about 0.2 mi across. You'll find it in Nipissing District. Closest neighbour on DepthScout: Bronson Lake, 1 mi north of here.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 6 to 21 ft, and winter fish settle into 3 to 20 ft. The spot to know is Deep basin, a deep basin in about 18 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.
| Season | Depth | Best window | Start at | Go-to baits |
