794-acre lake in Kenora District, Ontario. The lake tops out around 28 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 798 acres, worked by 15.6 miles of shoreline, with 3 islands in the mix. An index of 3.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 76% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 2.4 mi with a 1.6-mi widest point. Kenora District claims this one. Its nearest charted neighbour, Crossland Lake, is 2 mi to the northwest.
Spring puts cisco (lake herring) in skinny water — 7 to 28 ft is the zone. Summer fish stay in 8 to 28 ft, and winter fish hold in 8 to 28 ft. Deep basin is the standout, a deep basin at roughly 24 ft, rated prime for spring cisco (lake herring). Plan around early morning in the warm months. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.
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 | 7 to 28 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (24 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 8 to 28 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (24 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 | 8 to 28 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (24 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 8 to 28 ft, and winter fish settle into 8 to 28 ft. The spot to know is Break off the point, a drop-off in about 13 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 28 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (13 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 8 to 28 ft, wintering in 8 to 28 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

Spring northern pike on Guernsey Lake hold shallow, usually 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. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 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 (3 ft) | Tip-ups, Large jigging spoon |
