856-acre lake in Cochrane District, Ontario. The lake tops out around 30 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1985 (an MNRF lake survey). Species by species, here's what the data says the year looks like.
On the chart, Twopeak Lake draws 854 acres inside 7.8 miles of shoreline. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 74% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 2.4 mi end to end and 1.2 mi across at its widest. The water lies in Cochrane District. Closest neighbour on DepthScout: Wasicho Lake, 2 mi north of here.
When the water first warms, lake whitefish slide up into 9 to 30 ft. There's no big seasonal slide here — summer means 9 to 30 ft, winter 9 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 26 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 30 ft | midday & dawn | Break off the point (23 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 9 to 30 ft | dawn | Deep basin (26 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (23 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (26 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, cisco (lake herring) slide up into 8 to 30 ft. There's no big seasonal slide here — summer means 9 to 30 ft, winter 9 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 26 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 30 ft | dawn & dusk | Deep basin (26 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 9 to 30 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 (23 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 9 to 30 ft | dawn | Deep basin (26 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 9 to 30 ft game here, winter a 9 to 30 ft one. The chart's best answer is Break off the point — drop-off, 23 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 9 to 30 ft | dusk & dawn | Break off the point (23 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 9 to 30 ft | dusk & night | Break off the point (23 ft) | Jigging rap, Jig + big minnow |
| Winter | 9 to 30 ft | dusk & dawn | Deep basin (26 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Twopeak Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 9 to 30 ft. The chart's best answer is Deep basin — deep basin, 26 ft, prime for fall. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (26 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 1 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (23 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (2 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
