482-acre lake in Simcoe County, Ontario. The lake tops out around 40 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 485 acres of water rimmed by 26.1 miles of bank, with 70 islands in the mix. A development index of 8.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. 63% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 3.5 mi long by 0.9 mi wide at the broadest reach. You'll find it in Simcoe County. Closest neighbour on DepthScout: Eastern L., 1 mi north of here.
The spring pattern is a shallow one: lake trout in 10 to 40 ft. The depth story barely changes: 12 to 40 ft through summer, 10 to 40 ft in winter. The spot to know is Deep basin, a deep basin in about 38 ft of water that rates prime for lake trout in summer. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.

Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
