1,161-acre lake in Thunder Bay District, Ontario. The lake tops out around 5 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 1973, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 1,166 acres wrapped in 9.7 miles of bank, with 10 islands in the mix. With a 2 development index there's bank structure worth casting at, in moderation. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 2.3 mi, about 1.4 mi across. It sits in Thunder Bay District. Its nearest charted neighbour, Upper Kaogomok Lake, is 11 mi to the southwest.
Start shallow in spring: lake whitefish sit in 2 to 5 ft that time of year. They don't go far with the seasons — 2 to 5 ft covers summer, 2 to 5 ft covers winter. The spot to know is Deep basin, a deep basin in about 5 ft of water that rates good for lake whitefish in summer. Warm-month bites cluster around early morning. 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 | 2 to 5 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (4 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 2 to 5 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (5 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 1 to 5 ft chart-limited; documented 8 to 30 ft | dusk | Break off the point (4 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 2 to 5 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (5 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, walleye run shallow here, mostly 1 to 5 ft. Summer keeps them at 2 to 5 ft, and they winter in 2 to 5 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 4 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 2 to 5 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (4 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 2 to 5 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (4 ft) | Jigging rap, Jig + big minnow |
| Winter | 2 to 5 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (5 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 1 to 5 ft. The depth story barely changes: 2 to 5 ft through summer, 2 to 5 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. 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 | 1 to 5 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 5 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 5 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 5 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 1 to 5 ft. There's no big seasonal slide here — summer means 2 to 5 ft, winter 2 to 5 ft. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

Buck Lake is about 5 ft (2 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1973, a decades-old survey (a transect sounding survey).
Anglers target lake whitefish, walleye, yellow perch, northern pike on Buck Lake.
Deep basin is the top-rated area: a deep basin in about 5 ft of water that rates good for lake whitefish in summer. The interactive chart above rates every spot for each species and season.
For lake whitefish, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
