166-acre lake in Parry Sound District, Ontario. The lake tops out around 33 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 1977, a decades-old survey (an MNRF lake survey). The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 166 acres wrapped in 3.7 miles of bank. A middling shoreline index (2.1) gives it some bays to work without being a maze. About 66% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 1 mi end to end and 0.6 mi across at its widest. Parry Sound District claims this one. Its nearest charted neighbour, Long Lake, is 1 mi to the south.
In spring, cisco (lake herring) run shallow here, mostly 8 to 33 ft. Summer keeps them at 10 to 33 ft, and they winter in 10 to 33 ft. Spring cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 33 ft. Fish it in early morning and you'll meet the bite. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 33 ft | dawn & dusk | Deep basin (33 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 10 to 33 ft | dawn | Deep basin (33 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (8 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 10 to 33 ft | dawn | Deep basin (33 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 10 to 33 ft. Deep basin is the standout, a deep basin at roughly 33 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 | 10 to 30 ft | dawn | Break off the point (8 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 10 to 33 ft. Put Break off the point first on the milk run — a drop-off near 8 ft that grades prime for fall. 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 | Secondary point (6 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (8 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (8 ft) | Jerkbait, Blade bait |
| Winter | 10 to 33 ft | midday | Break off the point (8 ft) | Blade bait, Hair jig |
Spring largemouth bass on Trout Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 10 to 33 ft. The chart's best answer is Secondary point — point, 6 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |

| Winter | 10 to 33 ft | midday | Break off the point (8 ft) | Blade bait, Jigging spoon |
In spring, pumpkinseed run shallow here, mostly 1 to 8 ft. Midsummer fish sit out in 2 to 10 ft before dropping to 6 to 18 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.

|---|---|---|---|---|
| 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) |

| Winter | 6 to 18 ft | dawn | Break off the point (8 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 10 to 25 ft one. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. 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) | |
