27-acre lake in Nipissing District, Ontario. The lake tops out around 23 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 27 acres of water rimmed by 1.3 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 80% of this chart, as modeled. 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: Norway Lake, 1 mi north of here.

The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
