25-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 13 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Species by species, here's what the data says the year looks like.
The drawn water covers 25 acres wrapped in 0.8 miles of bank. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. Muskoka District Municipality claims this one. If the bite dies, Hesners Lake is 2 mi to the east.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 4 to 13 ft, wintering in 4 to 13 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 13 ft | dawn | Deep basin (11 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 13 ft | midday | Deep basin (11 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 13 ft | midday & dawn | Deep basin (11 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. They move out to 3 to 12 ft in summer and finish the year down in 4 to 13 ft. If you only fish one area, make it Deep basin: a deep basin around 11 ft that scores prime in winter. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 4 to 13 ft | dusk | Deep basin (11 ft) | |
| Winter | 4 to 13 ft | midday | Deep basin (11 ft) |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 11 ft.
