2,055-acre lake in Kenora District, Ontario. The lake tops out around 25 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 2,056 acres, worked by 17.9 miles of shoreline, broken up by 2 islands. With a shoreline index of 2.8, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 73% of this chart, as modeled. Figure 3.7 mi of water from one end to the other, 1.9 mi at the beam. It sits in Kenora District. Its nearest charted neighbour, Godden Lake, is 3 mi to the southwest.
In spring, cisco (lake herring) run shallow here, mostly 6 to 25 ft. Summer keeps them at 8 to 25 ft, and they winter in 8 to 25 ft. Deep basin is the standout, a deep basin at roughly 21 ft, rated prime for spring 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.
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 | 6 to 25 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (21 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 8 to 25 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (21 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (11 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 8 to 25 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (21 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 8 to 25 ft for winter. The spot to know is Break off the point, a drop-off in about 11 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.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |

In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 8 to 25 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 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.

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, 3 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 (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (11 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (11 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 |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Summer is an 8 to 25 ft game here, winter an 8 to 25 ft one. The chart's best answer is Main-lake point — point, 8 ft, prime for fall. Best bite is early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.

Main-lake point is the standout, a point at roughly 8 ft, rated prime for summer rock bass. Time it for the evening. You won't need more than a ned rig (small) or a marabou jig most summer days.
