2,414-acre lake in Kenora District, Ontario. The lake tops out around 49 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 1979, a decades-old survey (an MNRF lake survey). What the data behind the map says about each species, season by season:
Onepine Lake maps at 2,425 acres behind 31.9 miles of shoreline, broken up by 7 islands. An index of 4.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 92% of the surface — that's where the groceries are. End to end it runs roughly 4.4 mi, about 2.7 mi across. It sits in Kenora District. Cairns Lake sits 9 mi southeast — the closest neighbouring chart.
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 15 to 49 ft, then a winter hold in 12 to 49 ft. Put Deep basin first on the milk run — a deep basin near 45 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
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 | 10 to 40 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 15 to 49 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (45 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 49 ft chart-limited; documented 10 to 50 ft | dusk & dawn | Main-lake point (1 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 12 to 49 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (45 ft) | White tube jig, Airplane jig |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 15 to 49 ft, wintering in 15 to 49 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 45 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Shallow feeding flat (18 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 15 to 49 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (45 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | open water | Small spoon (gold), Jig + plastic larva |
| Winter | 15 to 49 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (45 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Deep basin, a deep basin in the 45 ft range, prime in winter. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| 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 | Shallow feeding flat (18 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Deep basin (45 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (45 ft) | Jigging spoon + minnow head, Rattle bait |
Spring northern pike on Onepine Lake hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (18 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow feeding flat (18 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
Early season burbot use the shallows, holding in 15 to 49 ft. Even in summer they hold at 15 to 49 ft; winter keeps them in 12 to 49 ft. Put Deep basin first on the milk run — a deep basin near 45 ft that grades prime for spring. In summer the feeding windows fall in after dark and midday. Tie on a heavy jig + cut bait and you're in the game.

Onepine Lake is about 49 ft (15 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (an MNRF lake survey).
Anglers target lake trout, lake whitefish, walleye, northern pike, burbot on Onepine Lake.
Deep basin is the top-rated area: a deep basin in about 45 ft of water that rates prime for lake trout in summer. The map above holds the full rated-spot list for every species and season.
For lake trout, 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.
