268-acre lake in Parry Sound District, Ontario. The lake tops out around 60 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 1968, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
Sucker Lake maps at 269 acres behind 4.8 miles of shoreline — one island included. With a 2.1 development index there's bank structure worth casting at, in moderation. 9% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 1.3 mi of water from one end to the other, 0.8 mi at the beam. It sits in Parry Sound District. Carter Lake sits 1 mi southwest — the closest neighbouring chart.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 18 to 60 ft, then a winter hold in 15 to 60 ft. Start at Deep basin. It's a deep basin holding about 60 ft of water and rates prime come summer. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (40 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 18 to 60 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (60 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (40 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 60 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (60 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: cisco (lake herring) in 10 to 40 ft. As the season builds they drop to 18 to 60 ft, wintering in 20 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 60 ft range, prime in summer. Time it for early morning. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (40 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 18 to 60 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (60 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 | 20 to 60 ft | dawn | Deep basin (60 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 40 ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| 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 | open water | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (40 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (40 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 20 to 45 ft. If you only fish one area, make it Break off the point: a drop-off around 40 ft that scores prime in winter. Best bite is early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (1 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (1 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (40 ft) | Blade bait, Hair jig |
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is an 8 to 20 ft game here, winter a 15 to 35 ft one. Start at Break off the point. It's a drop-off holding about 40 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| 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 | open water | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (40 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: rock bass in 2 to 10 ft. As the season builds they drop to 5 to 20 ft, wintering in 12 to 30 ft. Top water on the chart: Main-lake point, a point in the 1 ft range, good in summer. Time it for the evening. Summer baits: a ned rig (small) or a marabou jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (1 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (1 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | open water | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | open water | Tungsten jig + plastic, Small spoon + spike |
