370-acre lake in Rainy River District, Ontario. The lake tops out around 40 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. Every species below gets its seasonal read from the same numbers driving the chart.
Keckush Lake maps at 368 acres behind 7.5 miles of shoreline. A development index of 2.8 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 98% of the water is 15 ft or less, the band where the food chain lives. Call it 2.2 mi long by 0.8 mi wide at the broadest reach. Rainy River District claims this one. Companion Lakes sits 2 mi south — the closest neighbouring chart.
Start shallow in spring: lake whitefish sit in 12 to 40 ft that time of year. They don't go far with the seasons — 12 to 40 ft covers summer, 12 to 40 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 40 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.
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 | 12 to 40 ft chart-limited; documented 15 to 45 ft | midday & dawn | Shallow feeding flat (13 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 12 to 40 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (40 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (2 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 12 to 40 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (40 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. They don't go far with the seasons — 12 to 40 ft covers summer, 12 to 40 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 40 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.
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 | 10 to 40 ft | dawn & dusk | Deep basin (40 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 12 to 40 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (40 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (2 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 12 to 40 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (40 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, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Deep basin is the standout, a deep basin at roughly 40 ft, rated prime for winter 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 (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Shallow feeding flat (13 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Deep basin (40 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (40 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 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Deep basin, a deep basin in the 40 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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow feeding flat (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (40 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (40 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 1 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 (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow feeding flat (13 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow feeding flat (13 ft) | Tip-ups, Large jigging spoon |
When the water first warms, burbot slide up into 12 to 40 ft. There's no big seasonal slide here — summer means 12 to 40 ft, winter 10 to 40 ft. Start at Deep basin. It's a deep basin holding about 40 ft of water and rates prime come spring. The feeding windows run after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.

|---|---|---|---|---|
| Spring | 12 to 40 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (40 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 12 to 40 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (40 ft) | Heavy jig + cut bait |
| Fall | 12 to 40 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (40 ft) | Glow spoon + minnow head, Blade bait (slow) |

Keckush Lake is about 40 ft (12 m) deep at its deepest point. 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.
Anglers target lake whitefish, cisco (lake herring), walleye, yellow perch, northern pike, burbot on Keckush Lake.
Deep basin is the top-rated area: a deep basin in about 40 ft of water that rates prime for lake whitefish in summer. The interactive chart above rates every spot for each species and season.
For lake whitefish, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
