1,669-acre lake in Rainy River District, Ontario. The lake tops out around 47 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 rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 1,691 acres, worked by 31.9 miles of shoreline, with 14 islands in the mix. An index of 5.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 91% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 3.4 mi, about 1.8 mi across. It sits in Rainy River District. If the bite dies, Nym Lake is 3 mi to the south.
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Break off the point — drop-off, 8 ft, prime for fall. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| 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 (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow feeding flat (15 ft) | Tip-ups, Large jigging spoon |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 20 to 45 ft one. The chart's best answer is Break off the point — drop-off, 8 ft, prime for fall. Best bite is early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (8 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (8 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Deep basin (40 ft) | Blade bait, Hair jig |
Structure-wise the chart holds 7 features, led in depth by Deep basin at roughly 40 ft.
