18-acre lake in Nipissing District, Ontario. The lake tops out around 29 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:
Drawn out, this is 18 acres of water rimmed by 0.9 miles of bank. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 65% of this chart, as modeled. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. The water lies in Nipissing District. Closest neighbour on DepthScout: Montreuil Lake, 2 mi north of here.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 9 to 29 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 25 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
