589-acre lake in Thunder Bay District, Ontario. The lake tops out around 26 ft. The depth data here comes from the Ontario MNRF survey of 1983 (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 591 acres, worked by 10.3 miles of shoreline, with 4 islands in the mix. An index of 3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 69% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 2 mi long by 1.2 mi wide at the broadest reach. It sits in Thunder Bay District. Its nearest charted neighbour, Heathcote Lake, is 5 mi to the northeast.
Spring puts lake whitefish in skinny water — 8 to 26 ft is the zone. Summer fish stay in 8 to 26 ft, and winter fish hold in 8 to 26 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 26 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
