40-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 17 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1913, a decades-old survey (an MNRF lake survey). What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 40 acres wrapped in 1.3 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. End to end it runs roughly 0.5 mi, about 0.3 mi across. Muskoka District Municipality claims this one. Its nearest charted neighbour, Dotty Lake, is 1 mi to the northeast.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 5 to 17 ft, and winter fish settle into 5 to 17 ft. Deep basin is the standout, a deep basin at roughly 12 ft, rated prime for fall 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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 17 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 17 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 17 ft | midday & dawn | Deep basin (12 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 5 to 17 ft, then a winter hold in 5 to 17 ft. Put Break off the point first on the milk run — a drop-off near 7 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 5 to 17 ft | dawn & dusk | Break off the point (7 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 17 ft | midday & dawn | Break off the point (7 ft) | Jerkbait, Blade bait |
| Winter | 5 to 17 ft | midday | Break off the point (7 ft) | Blade bait, Hair jig |
In spring, pumpkinseed run shallow here, mostly 1 to 8 ft. Midsummer fish sit out in 2 to 10 ft before dropping to 5 to 17 ft for winter. Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 1 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 17 ft | dawn | Deep basin (12 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season brown bullhead use the shallows, holding in 2 to 8 ft. Summer is a 3 to 12 ft game here, winter a 5 to 17 ft one. The chart's best answer is Deep basin — deep basin, 12 ft, prime for 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 (1 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (1 ft) | |
| Fall | 5 to 15 ft | dusk | Deep basin (12 ft) | |
| Winter | 5 to 17 ft | midday | Deep basin (12 ft) |
