232-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 36 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 233 acres of water rimmed by 5.8 miles of bank. That shoreline is heavily fingered (development index 2.7) — bays, points and pockets everywhere, which multiplies the fishable edge. About 55% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1.7 mi with a 0.5-mi widest point. The water lies in Muskoka District Municipality. For a second option, Cassidy Lake lies 1 mi southwest.
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Back-bay flat: a weed flat around 6 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (36 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (36 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 11 to 36 ft. Top water on the chart: Main-lake point, a point in the 11 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (11 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (20 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (11 ft) | Jerkbait, Blade bait |
| Winter | 11 to 36 ft | midday | Break off the point (20 ft) | Blade bait, Hair jig |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for largemouth bass in spring. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (20 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (11 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (20 ft) | Blade bait, Jigging spoon |
Spring rock bass on Bass Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 5 to 20 ft, and by winter most fish are in 12 to 30 ft. The chart's best answer is Main-lake point — point, 11 ft, prime for summer. Prime time lands in the evening. The summer box starts with a ned rig (small) or a marabou jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Secondary point (8 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (11 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Break off the point (20 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Break off the point (20 ft) | Tungsten jig + plastic, Small spoon + spike |
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 3 to 12 ft, wintering in 10 to 25 ft. Spring brown bullhead concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. 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 (2 ft) | |
| Summer | 3 to 12 ft | night & dusk | Back-bay flat (6 ft) | |
| Fall | 5 to 15 ft | dusk | Back-bay flat (6 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (36 ft) |
In spring, burbot run shallow here, mostly 11 to 36 ft. Summer keeps them at 11 to 36 ft, and they winter in 9 to 36 ft. Deep basin is the standout, a deep basin at roughly 36 ft, rated prime for spring burbot. Time it for after dark and midday. You won't need more than a heavy jig + cut bait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 11 to 36 ft | night & dusk | Deep basin (36 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 11 to 36 ft | night & midday | Deep basin (36 ft) | Heavy jig + cut bait |
| Fall | 11 to 36 ft | night & dusk | Deep basin (36 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 9 to 36 ft | night & dusk | Deep basin (36 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
6 pieces of structure are mapped here — Deep basin, around 36 ft, is the deepest of them.
