9,856-acre lake in Kenora District, Ontario. The lake tops out around 74 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Every species below gets its seasonal read from the same numbers driving the chart.
Churchill Lake maps at 9,893 acres behind 138.5 miles of shoreline, broken up by 37 islands. An index of 9.9 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 50% of this chart, as modeled. Tip to tip the water measures near 13.4 mi with a 6.9-mi widest point. It sits in Kenora District. If the bite dies, St. Raphael Lake is 5 mi to the south.
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 22 to 74 ft, and winter fish settle into 25 to 70 ft. Deep basin is the standout, a deep basin at roughly 63 ft, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
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 | 15 to 45 ft | midday & dawn | Break off the point (33 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 22 to 74 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (63 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (6 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (63 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 22 to 74 ft, and winter fish settle into 20 to 60 ft. Deep basin is the standout, a deep basin at roughly 63 ft, rated prime for summer cisco (lake herring). Time it for early morning. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.

The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 15 to 35 ft before dropping to 20 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 33 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (6 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (33 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (33 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (33 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: sauger in 4 to 18 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 45 ft. Top water on the chart: Rock reef, a rock pile in the 6 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bottom bouncer + crawler or a 3-way rig with stickbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Rock reef (6 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |

In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |

| Winter | 15 to 35 ft | midday & dawn | Break off the point (33 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 6 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
