317-acre lake in Cochrane District, Ontario. The lake tops out around 30 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
Gurney Lake maps at 319 acres behind 6.6 miles of shoreline, with 2 islands in the mix. With a shoreline index of 2.6, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 80% of the surface — that's where the groceries are. The basin spans about 2 mi end to end and 0.7 mi across at its widest. It sits in Cochrane District. Its nearest charted neighbour, Maxwell Lake, is 2 mi to the south.
Start shallow in spring: cisco (lake herring) sit in 8 to 30 ft that time of year. They don't go far with the seasons — 9 to 30 ft covers summer, 9 to 30 ft covers winter. The spot to know is Deep basin, a deep basin in about 28 ft of water that rates prime for cisco (lake herring) in spring. Warm-month bites cluster around early morning. 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 | 8 to 30 ft | dawn & dusk | Deep basin (28 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 9 to 30 ft | dawn | Deep basin (28 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (13 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 9 to 30 ft | dawn | Deep basin (28 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 9 to 30 ft before dropping to 9 to 30 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 13 ft. Fish it in the evening and early morning and you'll meet the bite. 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 | 9 to 30 ft | dusk & dawn | Break off the point (13 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 9 to 30 ft | dusk & night | Break off the point (13 ft) | Jigging rap, Jig + big minnow |
| Winter | 9 to 30 ft | dusk & dawn | Deep basin (28 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 30 ft for winter. The spot to know is Deep basin, a deep basin in about 28 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. 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 | 10 to 30 ft | dawn | Deep basin (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (28 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (28 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. The feeding windows run 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 (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (13 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 |
