668-acre lake in Haliburton County, Ontario. The lake tops out around 120 ft. The depth data here comes from the Ontario MNRF survey of 1968, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 671 acres wrapped in 10.3 miles of bank — 2 islands included. A development index of 2.8 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 19% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1.8 mi long by 1.4 mi wide at the broadest reach. It sits in Haliburton County. Its nearest charted neighbour, Silver Buck Lake, is 2 mi to the east.
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 15 to 35 ft. Shallow bay flat is the standout, a feeding flat at roughly 6 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

The summer box starts with a bucktail or a weedless spoon over cabbage.

Early season burbot use the shallows, holding in 25 to 70 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 15 to 60 ft.
