527-acre lake in Parry Sound District, Ontario. The lake tops out around 40 ft. The depth data here comes from the Ontario MNRF survey of 1975, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 529 acres, worked by 20.5 miles of shoreline, with 17 islands in the mix. That shoreline is heavily fingered (development index 6.4) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 65% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 4.9 mi end to end and 1.3 mi across at its widest. Parry Sound District claims this one. Harris Lake sits 3 mi east — the closest neighbouring chart.
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. They don't go far with the seasons — 12 to 40 ft covers summer, 12 to 40 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 40 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (40 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 12 to 40 ft | dawn | Deep basin (40 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (3 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 12 to 40 ft | dawn | Deep basin (40 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 4 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow feeding flat (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (40 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (40 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 12 to 40 ft. If you only fish one area, make it Main-lake point: a point around 6 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (6 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (6 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (6 ft) | Jerkbait, Blade bait |
| Winter | 12 to 40 ft | midday | Break off the point (3 ft) | Blade bait, Hair jig |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Deep basin (40 ft) | Blade bait, Jigging spoon |
Start shallow in spring: rock bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 20 ft; cold water stacks them in 12 to 30 ft. Top water on the chart: Main-lake point, a point in the 6 ft range, prime in summer. Fish it in the evening and you'll meet the bite. Throw a ned rig (small) or a marabou jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (6 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (6 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Main-lake point (6 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Deep basin (40 ft) | Tungsten jig + plastic, Small spoon + spike |
