335-acre lake in Algoma District, Ontario. The lake tops out around 70 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 1959, a decades-old survey (an MNRF lake survey). The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 333 acres, worked by 3.6 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 54% of this chart. End to end it runs roughly 1.3 mi, about 0.7 mi across. It sits in Algoma District. Mole Lake sits 1 mi northeast — the closest neighbouring chart.
Spring brook trout on Corine Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Main-lake point — point, 1 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow feeding flat (10 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 21 to 70 ft, then a winter hold in 18 to 70 ft. Start at Deep basin. It's a deep basin holding about 70 ft of water and rates prime come summer. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
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 | 21 to 70 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (70 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (49 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 18 to 70 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (70 ft) | White tube jig, Airplane jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Put Break off the point first on the milk run — a drop-off near 49 ft that grades good for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow feeding flat (10 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (49 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: cisco (lake herring) in 10 to 40 ft. As the season builds they drop to 21 to 70 ft, wintering in 20 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 70 ft range, prime in summer. Time it for early morning. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
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 | open water | Small silver spoon, Tiny swim jig (white) |
| Summer | 21 to 70 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (70 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (70 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |

Corine Lake is about 70 ft (21 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1959, a decades-old survey (an MNRF lake survey).
Anglers target brook trout, lake trout, rainbow trout, cisco (lake herring) on Corine Lake.
Deep basin is the top-rated area: a deep basin in about 70 ft of water that rates prime for lake trout in summer. Open the map above to see every rated spot for each species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
