242-acre lake in Parry Sound District, Ontario. The lake tops out around 49 ft. The depth data here comes from the Ontario MNRF survey of 2011 (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 243 acres of water rimmed by 8.4 miles of bank, with 4 islands in the mix. The 3.9 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 45% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 1.5 mi of water from one end to the other, 0.7 mi at the beam. The water lies in Parry Sound District. Closest neighbour on DepthScout: Carruthers Lake, 1 mi west of here.
Early season cisco (lake herring) use the shallows, holding in 10 to 40 ft. Expect a summer slide to 15 to 49 ft, then a winter hold in 15 to 49 ft. Put Deep basin first on the milk run — a deep basin near 49 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (49 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 15 to 49 ft | dawn | Deep basin (49 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 15 to 49 ft | dawn | Deep basin (49 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Start at Shallow bay flat. It's a weed flat holding about 5 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (32 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (32 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (32 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 20 to 45 ft. The spot to know is Main-lake point, a point in about 13 ft of water that rates prime for smallmouth bass in fall. Warm-month bites cluster around early morning and the evening. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Secondary point (12 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (13 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (13 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (32 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. As the season builds they drop to 8 to 20 ft, wintering in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (5 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (13 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (13 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (32 ft) | Blade bait, Jigging spoon |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 6 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 5 ft that grades prime for spring. In summer the feeding windows fall in the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (5 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (5 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (5 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 10 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 5 ft, rated prime for spring brown bullhead. Time it for after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (5 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (5 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (5 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (49 ft) |
