31-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 14 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 31 acres of water rimmed by 0.8 miles of bank. The basin is a simple one (shoreline index 1) — close to a bowl, so the structure on the chart matters more than the bank. 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 0.3 mi wide at the broadest reach. You'll find it in Muskoka District Municipality. For a second option, Fawn Lake lies 3 mi southwest.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 4 to 14 ft game here, winter a 4 to 14 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| 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 14 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 14 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 14 ft | midday & dawn | Deep basin (12 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 4 to 14 ft before dropping to 4 to 14 ft for winter. Winter smallmouth bass concentrate at Shoreline break, a prime-rated drop-off around 6 ft. Fish it in early morning and the evening and you'll meet the bite. 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 | open water | Ned rig, Tube jig |
| Summer | 4 to 14 ft | dawn & dusk | Shoreline break (6 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 4 to 14 ft | midday & dawn | Shoreline break (6 ft) | Jerkbait, Blade bait |
| Winter | 4 to 14 ft | midday | Shoreline break (6 ft) | Blade bait, Hair jig |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 4 to 14 ft; cold water stacks them in 4 to 14 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. 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 | 4 to 14 ft | dawn & dusk | Shoreline break (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 14 ft | midday & dawn | Shallow bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 14 ft | midday | Shoreline break (6 ft) | Blade bait, Jigging spoon |
Come spring, look for rock bass tight to the bank in 2 to 10 ft. They move out to 4 to 14 ft in summer and finish the year down in 4 to 14 ft. If you only fish one area, make it Shoreline break: a drop-off around 6 ft that scores prime in fall. Best bite is the evening. A ned rig (small) or a marabou jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | 1/16 oz jig + grub, Small inline spinner |
| Summer | 4 to 14 ft | dusk | Shoreline break (6 ft) | Ned rig (small), Marabou jig |
| Fall | 4 to 14 ft | midday | Shoreline break (6 ft) | Small tube jig, Inline spinner |
| Winter | 4 to 14 ft | midday | Deep basin (12 ft) | Tungsten jig + plastic, Small spoon + spike |
Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. They move out to 2 to 10 ft in summer and finish the year down in 4 to 14 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is 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 | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 4 to 14 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Warm water sends them out to 3 to 12 ft; cold water stacks them in 4 to 14 ft. Top water on the chart: Deep basin, a deep basin in the 12 ft range, prime in winter. Fish it in after dark and the evening and you'll meet the bite.
| 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 14 ft | dusk | Deep basin (12 ft) | |
| Winter | 4 to 14 ft | midday | Deep basin (12 ft) |
Count 4 structure marks on this chart. The deepest, Deep basin, sits near 12 ft.
