1,481-acre lake in Algoma District, Ontario. The lake tops out around 110 ft. The depth data here comes from the Ontario MNRF survey of 1965, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 1,488 acres, worked by 33.8 miles of shoreline — 51 islands included. An index of 6.3 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 40% of this chart. End to end it runs roughly 3.8 mi, about 2.6 mi across. It sits in Algoma District. Wabigoon Lake sits 2 mi southeast — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Main-lake point. It's a point holding about 13 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
