310-acre lake in Kenora District, Ontario. The lake tops out around 36 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 an MNRF lake survey by the Ontario MNRF. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 311 acres wrapped in 6 miles of bank, with a single island in the mix. A development index of 2.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 63% of the water is 15 ft or less, the band where the food chain lives. Figure 2 mi of water from one end to the other, 0.5 mi at the beam. Kenora District claims this one. If the bite dies, Tackaberry Lake is 2 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.

In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 11 to 36 ft. Break off the point is the standout, a drop-off at roughly 21 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) 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 | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (21 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 11 to 36 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (21 ft) | Jigging rap, Jig + big minnow |
| Winter | 11 to 36 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (36 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, northern pike slide up into 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. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| 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 | 8 to 20 ft | dawn & dusk | Break off the point (21 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (21 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: cisco (lake herring) sit in 9 to 36 ft that time of year. They don't go far with the seasons — 11 to 36 ft covers summer, 11 to 36 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 36 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
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 | 9 to 36 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (36 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 11 to 36 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (36 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (21 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 11 to 36 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (36 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Start shallow in spring: lake whitefish sit in 11 to 36 ft that time of year. They don't go far with the seasons — 11 to 36 ft covers summer, 11 to 36 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 36 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
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 | 11 to 36 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (21 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 11 to 36 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (36 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (21 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 11 to 36 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (36 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Deep basin, a deep basin in the 36 ft range, prime in fall. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| 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 | 10 to 30 ft | dawn | Break off the point (21 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (36 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (36 ft) | Tungsten jig + spikes, Rattle spoon (small) |

Anglers target walleye, northern pike, cisco (lake herring), lake whitefish, yellow perch on Blair Lake.
Break off the point is the top-rated area: a drop-off in about 21 ft of water that rates prime for walleye in fall. Open the map above to see every rated spot for each species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
