665-acre lake in Kenora District, Ontario. The lake tops out around 14 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 1986 (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
The outline encloses 666 acres, worked by 8.4 miles of shoreline, broken up by an island. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. End to end it runs roughly 2.3 mi, about 0.8 mi across. Kenora District claims this one. Its nearest charted neighbour, Whitemud Lake, is 2 mi to the south.
Spring puts walleye in skinny water — 4 to 14 ft is the zone. Summer fish stay in 4 to 14 ft, and winter fish hold in 4 to 14 ft. Winter walleye concentrate at Deep basin, a prime-rated deep basin around 13 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) 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 | 4 to 14 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 4 to 14 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Main-lake point (5 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 4 to 14 ft chart-limited; documented 12 to 40 ft | dusk & night | Main-lake point (5 ft) | Jigging rap, Jig + big minnow |
| Winter | 4 to 14 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (13 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 4 to 14 ft, and winter fish settle into 4 to 14 ft. The spot to know is Deep basin, a deep basin in about 13 ft of water that rates prime for yellow perch in fall. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.

| 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 | 4 to 14 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 14 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (13 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 14 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (13 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 4 to 14 ft, then a winter hold in 4 to 14 ft. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

| 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 | 4 to 14 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Main-lake point (5 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 14 ft chart-limited; documented 6 to 18 ft | midday & dawn | Main-lake point (5 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 14 ft chart-limited; documented 5 to 15 ft | midday | Main-lake point (5 ft) | Tip-ups, Large jigging spoon |
Come spring, look for burbot tight to the bank in 4 to 14 ft. Through summer count on 4 to 14 ft; the winter hold is 4 to 14 ft. If you only fish one area, make it Deep basin: a deep basin around 13 ft that scores prime in spring. Best bite is after dark and midday. A heavy jig + cut bait is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 14 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (13 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 4 to 14 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (13 ft) | Heavy jig + cut bait |
| Fall | 4 to 14 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (13 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 4 to 14 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (13 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
The spring pattern is a shallow one: lake whitefish in 4 to 14 ft. The depth story barely changes: 4 to 14 ft through summer, 4 to 14 ft in winter. The spot to know is Deep basin, a deep basin in about 13 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.

6 pieces of structure are mapped here — Deep basin, around 13 ft, is the deepest of them.
