2,229-acre lake in Kenora District, Ontario. The lake tops out around 13 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 the Ontario MNRF survey of 1981 (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 2,239 acres wrapped in 46.9 miles of bank, broken up by 61 islands. An index of 7.1 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The basin spans about 4.7 mi end to end and 3.1 mi across at its widest. Kenora District claims this one. If the bite dies, Gooseneck Lake is 4 mi to the east.
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.

Spring puts lake whitefish in skinny water — 4 to 13 ft is the zone. Summer fish stay in 4 to 13 ft, and winter fish hold in 4 to 13 ft. Deep basin is the standout, a deep basin at roughly 13 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 13 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (3 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 4 to 13 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (13 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 3 to 13 ft chart-limited; documented 8 to 30 ft | dusk | Break off the point (3 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 4 to 13 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (13 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: walleye sit in 3 to 13 ft that time of year. They don't go far with the seasons — 4 to 13 ft covers summer, 4 to 13 ft covers winter. The spot to know is Deep basin, a deep basin in about 13 ft of water that rates prime for walleye in winter. 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.

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 4 to 13 ft, wintering in 4 to 13 ft. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 13 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 Swan Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 4 to 13 ft, and by winter most fish are in 4 to 13 ft. The chart's best answer is Shallow bay flat — weed flat, 2 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.

Spring smallmouth bass on Swan Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 4 to 13 ft, and by winter most fish are in 4 to 13 ft. The chart's best answer is Break off the point — drop-off, 3 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.

Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 4 to 13 ft, then a winter hold in 4 to 13 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
