6,029-acre lake in Cochrane District, Ontario. The lake tops out around 60 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 a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 6,056 acres of water rimmed by 36.7 miles of bank, with 8 islands in the mix. An index of 3.4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 53% of this chart. End to end it runs roughly 7.5 mi, about 2.8 mi across. You'll find it in Cochrane District. Closest neighbour on DepthScout: Lost Otter Lake, 4 mi southwest of here.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Put Break off the point first on the milk run — a drop-off near 29 ft that grades prime for fall. In summer the feeding windows fall in 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 | Rock reef (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (29 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (29 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (29 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Pierre Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. Put Break off the point first on the milk run — a drop-off near 29 ft that grades prime for summer. The feeding windows run 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 | Break off the point (29 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (29 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (29 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 1 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. 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 | Shallow feeding flat (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (7 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Main-lake point (7 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: burbot sit in 18 to 60 ft that time of year. They don't go far with the seasons — 18 to 60 ft covers summer, 15 to 60 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 58 ft range, prime in spring. Fish it in after dark and midday and you'll meet the bite. Throw a heavy jig + cut bait until the fish tell you otherwise.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 18 to 60 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (58 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 18 to 60 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (58 ft) | Heavy jig + cut bait |
| Fall | 18 to 60 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (58 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (58 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. Summer is an 18 to 60 ft game here, winter a 20 to 60 ft one. Start at Deep basin. It's a deep basin holding about 58 ft of water and rates prime come summer. The feeding windows run 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 | 10 to 40 ft | dawn & dusk | Break off the point (29 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 18 to 60 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (58 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |

When the water first warms, sauger slide up into 4 to 18 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 45 ft. If you only fish one area, make it Rock reef: a rock pile around 4 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bottom bouncer + crawler or a 3-way rig with stickbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Rock reef (4 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (29 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |

| Winter | 15 to 45 ft | dusk | Break off the point (29 ft) | Heavy jigging spoon, Jig + minnow (vertical) |

Break off the point is the top-rated area: a drop-off in about 29 ft of water that rates prime for walleye in fall. The interactive chart above rates every spot for each species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
