8,227-acre lake in Kenora District, Ontario. The lake tops out around 120 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 8,263 acres, worked by 75.4 miles of shoreline, with 40 islands in the mix. The 5.9 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 36% of this chart. Figure 7.2 mi of water from one end to the other, 5.7 mi at the beam. It sits in Kenora District. If the bite dies, Duck L. is 3 mi to the south.
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 40 to 90 ft, and winter fish settle into 25 to 70 ft. Rock reef is the standout, a rock pile at roughly 9 ft, rated prime for fall 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.
