1,897-acre lake in Cochrane District, Ontario. The lake tops out around 26 ft. The depth data here comes from the Ontario MNRF survey of 1986 (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 1,906 acres, worked by 10.6 miles of shoreline, with 5 islands in the mix. With a 1.7 development index there's bank structure worth casting at, in moderation. About 65% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 2.7 mi with a 2-mi widest point. Cochrane District claims this one. Guilfoyle Lake 17 sits 1 mi east — the closest neighbouring chart.
Start shallow in spring: lake whitefish sit in 8 to 26 ft that time of year. They don't go far with the seasons — 8 to 26 ft covers summer, 8 to 26 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 26 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 | 8 to 26 ft | midday & dawn | Break off the point (10 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 8 to 26 ft | dawn | Deep basin (26 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 7 to 26 ft | dusk | Break off the point (10 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 8 to 26 ft | midday & dawn | Deep basin (26 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: cisco (lake herring) sit in 7 to 26 ft that time of year. They don't go far with the seasons — 8 to 26 ft covers summer, 8 to 26 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 26 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 | 7 to 26 ft | dawn & dusk | Deep basin (26 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 8 to 26 ft | dawn | Deep basin (26 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (10 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 8 to 26 ft | dawn | Deep basin (26 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, 8 to 26 ft, and winter fish settle into 8 to 26 ft. Break off the point is the standout, a drop-off at roughly 10 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 | Main-lake point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 26 ft | dusk & dawn | Break off the point (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 26 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 26 ft | dusk & dawn | Deep basin (26 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 8 to 26 ft, wintering in 8 to 26 ft. Top water on the chart: Deep basin, a deep basin in the 26 ft range, prime in fall. 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 (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 26 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 26 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 26 ft | midday & dawn | Deep basin (26 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 |
| Winter | 5 to 15 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
