1,089-acre lake in Algoma District, Ontario. The lake tops out around 79 ft. The depth data here comes from the Ontario MNRF survey of 1978, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 1,094 acres of water rimmed by 8.5 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 6% of the surface — that's where the groceries are. Tip to tip the water measures near 2.9 mi with a 1.2-mi widest point. You'll find it in Algoma District. Closest neighbour on DepthScout: Foot Lake, 2 mi south of here.
When the water first warms, lake whitefish slide up into 15 to 45 ft. Summer is a 24 to 79 ft game here, winter a 25 to 70 ft one. Start at Deep basin. It's a deep basin holding about 78 ft of water and rates prime come summer. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.

Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
