241-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 1974, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 242 acres of water rimmed by 4.1 miles of bank, with 2 islands in the mix. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. 82% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 1.3 mi with a 0.5-mi widest point. The water lies in Muskoka District Municipality. For a second option, Pickering Lake lies 1 mi north.
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. Main-lake point is the standout, a point at roughly 6 ft, rated prime for fall smallmouth bass. Time it for early morning and the evening. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (6 ft) | Ned rig, Tube jig |
| Summer | 6 to 20 ft | dawn & dusk | Break off the point (9 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 20 ft | midday & dawn | Main-lake point (6 ft) | Jerkbait, Blade bait |
| Winter | 6 to 20 ft | midday | Break off the point (9 ft) | Blade bait, Hair jig |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 6 to 20 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 20 ft | midday | Break off the point (9 ft) | Blade bait, Jigging spoon |
Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 6 to 18 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Back-bay flat (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 6 to 20 ft. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for brown bullhead in winter. Warm-month bites cluster around 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 | 5 to 15 ft | dusk | Back-bay flat (6 ft) | |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) |
