29-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 20 ft. The depth data here comes from the Ontario MNRF survey of 1975, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 29 acres, worked by 1 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 65% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 0.3 mi with a 0.3-mi widest point. It sits in Muskoka District Municipality. Bigwind Lake sits 1 mi northwest — the closest neighbouring chart.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 6 to 20 ft for winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. 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 | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Summer pushes them deeper, 2 to 10 ft, and winter fish settle into 6 to 18 ft. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for pumpkinseed in winter. Warm-month bites cluster around the evening and early morning. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | open water | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (20 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. Expect a summer slide to 3 to 12 ft, then a winter hold in 6 to 20 ft. Start at Deep basin. It's a deep basin holding about 20 ft of water and rates prime come winter. Prime time lands in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | open water | |
| Summer | 3 to 12 ft | night & dusk | open water | |
| Fall | 5 to 15 ft | dusk | open water | |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) |
