9,519-acre lake in Cochrane District, Ontario. The lake tops out around 50 ft. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
The outline encloses 9,562 acres, worked by 21.7 miles of shoreline — 3 islands included. With a 1.6 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 83% of this chart. End to end it runs roughly 5.9 mi, about 3.6 mi across. Cochrane District claims this one. Clearwater Lake sits 4 mi northwest — the closest neighbouring chart.
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. Midsummer fish sit out in 15 to 50 ft before dropping to 15 to 50 ft for winter. The spot to know is Deep basin, a deep basin in about 49 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Shallow feeding flat (20 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 15 to 50 ft | dawn | Deep basin (49 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (3 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 15 to 50 ft | midday & dawn | Deep basin (49 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: cisco (lake herring) in 10 to 40 ft. Midsummer fish sit out in 15 to 50 ft before dropping to 15 to 50 ft for winter. The spot to know is Deep basin, a deep basin in about 49 ft of water that rates prime for cisco (lake herring) in summer. Plan around early morning in the warm months. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
| 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 50 ft | dawn | Deep basin (49 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Rock reef (3 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 15 to 50 ft | dawn | Deep basin (49 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 10 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (49 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, sauger run shallow here, mostly 4 to 18 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 45 ft for winter. Winter sauger concentrate at Deep basin, a prime-rated deep basin around 49 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bottom bouncer + crawler or a 3-way rig with stickbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Rock reef (3 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 | Break off the point (10 ft) | Jig + big minnow, Blade bait |
| Winter | 15 to 45 ft | dusk | Deep basin (49 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Shallow bay flat, a weed flat in about 12 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. 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 (12 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 | Break off the point (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Shallow feeding flat (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Back-bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (12 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (12 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (12 ft) | Tip-ups, Large jigging spoon |
