168-acre lake in Nipissing District, Ontario. The lake tops out around 22 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Coldspring Lake runs 168 acres with 3.2 miles of edge. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 88% of this chart, as modeled. Call it 1.4 mi long by 0.3 mi wide at the broadest reach. You'll find it in Nipissing District. Closest neighbour on DepthScout: Kennedy Lake, 3 mi northeast of here.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 7 to 22 ft, and winter fish settle into 3 to 20 ft. The spot to know is Deep basin, a deep basin in about 19 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.
