33-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 53 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 33 acres wrapped in 1.1 miles of bank. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 37% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. Muskoka District Municipality claims this one. South Tasso Lake sits 1 mi north — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 24 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
