402-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 33 ft. The depth data here comes from the Ontario MNRF survey of 2003 (an MNRF lake survey). Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 404 acres wrapped in 11.6 miles of bank — 4 islands included. A development index of 4.1 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 54% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 3.1 mi long by 0.6 mi wide at the broadest reach. It sits in Muskoka District Municipality. Its nearest charted neighbour, Lake Joseph, is 2 mi to the northwest.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 10 to 33 ft.

A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
