55-acre lake in Nipissing District, Ontario. The lake tops out around 22 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Butler Lake draws 55 acres inside 1.9 miles of shoreline. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. End to end it runs roughly 0.9 mi, about 0.2 mi across. You'll find it in Nipissing District. For a second option, Blueberry L. lies 1 mi west.
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.
