36-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 72 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What the data behind the map says about each species, season by season:
The drawn water covers 36 acres wrapped in 1.5 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 38% of the surface on the model — that's where the groceries are. The basin spans about 0.5 mi end to end and 0.3 mi across at its widest. Muskoka District Municipality claims this one. If the bite dies, Rose Lake is 1 mi to the northeast.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |

| Winter | 15 to 35 ft | midday & dawn | Break off the point (32 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, rock bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 5 to 20 ft before dropping to 12 to 30 ft for winter. Summer rock bass concentrate at Main-lake point, a prime-rated point around 18 ft. Fish it in the evening and you'll meet the bite. You won't need more than a ned rig (small) or a marabou jig most summer days.

Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a micro tube or a sponge spider (fly) most summer days.
