599-acre lake in Algoma District, Ontario. The lake tops out around 164 ft. The depth data here comes from the Ontario MNRF survey of 2023 (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 601 acres, worked by 12.3 miles of shoreline, with 5 islands in the mix. A development index of 3.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 18% of the water is 15 ft or less, the band where the food chain lives. Call it 2.3 mi long by 1.2 mi wide at the broadest reach. It sits in Algoma District. If the bite dies, Crystal Lake is 1 mi to the southeast.
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Put Main-lake point first on the milk run — a point near 13 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
