1,579-acre lake in Rainy River District, Ontario. The lake tops out around 160 ft. The depth data here comes from the Ontario MNRF survey of 1969, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Drawn out, this is 1,586 acres of water rimmed by 21.3 miles of bank, broken up by 9 islands. An index of 3.8 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 22% of this chart. End to end it runs roughly 3.9 mi, about 1.5 mi across. The water lies in Rainy River District. The nearest mapped water is Warner Lake, 2 mi to the northwest.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 50 to 120 ft, and winter fish settle into 20 to 80 ft. Main-lake point is the standout, a point at roughly 12 ft, rated prime for spring lake trout. Time it for early morning. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
