4,997-acre lake in Rainy River District, Ontario. The lake tops out around 180 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 5,019 acres wrapped in 34.7 miles of bank, broken up by 31 islands. A development index of 3.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 13% of the surface — that's where the groceries are. Tip to tip the water measures near 4.7 mi with a 3.4-mi widest point. Rainy River District claims this one. Smoulder Lake sits 3 mi south — the closest neighbouring chart.
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 50 to 120 ft game here, winter a 20 to 80 ft one. The chart's best answer is Break off the point — drop-off, 62 ft, prime for winter. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.

|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Sharp break (43 ft) | Casting spoon over shoals, Jerkbait (shallow) |

A blade bait vertical or a small jigging spoon covers the summer program.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. The spot to know is Sharp break, a drop-off in about 43 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
