747-acre lake in Thunder Bay District, Ontario. The lake tops out around 33 ft. The depth data here comes from the Ontario MNRF survey of 1982 (a transect sounding survey). Species by species, here's what the data says the year looks like.
The drawn water covers 750 acres wrapped in 11.9 miles of bank, with 4 islands in the mix. The 3.1 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 90% of this chart. The basin spans about 2.4 mi end to end and 1.2 mi across at its widest. It sits in Thunder Bay District. If the bite dies, Loganberry Lake is 2 mi to the west.
In spring, lake whitefish run shallow here, mostly 10 to 33 ft. Summer keeps them at 10 to 33 ft, and they winter in 10 to 33 ft. Deep basin is the standout, a deep basin at roughly 32 ft, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
