71-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 55 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 70 acres wrapped in 2.3 miles of bank. A middling shoreline index (2) gives it some bays to work without being a maze. Roughly 47% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 0.9 mi of water from one end to the other, 0.3 mi at the beam. It sits in Muskoka District Municipality. If the bite dies, Dotty Lake is 1 mi to the southeast.
Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 17 to 55 ft, wintering in 17 to 55 ft. Summer cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 47 ft. Warm-month bites cluster around early morning. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.

A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

The summer box starts with a drop shot (goby/minnow) or a ned rig.

Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Warm-month bites cluster around the evening and early morning.
