3,925-acre lake in Parry Sound District, Ontario. The lake tops out around 80 ft. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 3,943 acres wrapped in 49.8 miles of bank, with 27 islands in the mix. An index of 5.7 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 41% of the surface — that's where the groceries are. Call it 8.6 mi long by 2.2 mi wide at the broadest reach. Parry Sound District claims this one. If the bite dies, Beaver Lake is 2 mi to the southwest.
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Warm water sends them out to 24 to 80 ft; cold water stacks them in 25 to 70 ft. Top water on the chart: Deep basin, a deep basin in the 79 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Sharp break (42 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 24 to 80 ft | dawn | Deep basin (79 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (5 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Sharp break (42 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. Warm water sends them out to 40 to 80 ft; cold water stacks them in 20 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 79 ft range, prime in summer. 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 | Break off the point (10 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (79 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Rock reef (5 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Sharp break (42 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Sharp break is the standout, a drop-off at roughly 22 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Sharp break (22 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Sharp break (22 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Sharp break (22 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts sauger in skinny water — 4 to 18 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 45 ft. Rock reef is the standout, a rock pile at roughly 5 ft, rated prime for spring sauger. Plan around early morning and the evening in the warm months. A bottom bouncer + crawler or a 3-way rig with stickbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Rock reef (5 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (10 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |
| Fall | 12 to 35 ft | dusk & dawn | Sharp break (22 ft) | Jig + big minnow, Blade bait |
| Winter | 15 to 45 ft | dusk | Sharp break (42 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
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: Weed flat, a weed flat in the 3 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 | Weed flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Sharp break (22 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Sharp break (22 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 2 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 (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
