258-acre lake in Parry Sound District, Ontario. The lake tops out around 39 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 261 acres, worked by 13.4 miles of shoreline, broken up by an island. A development index of 5.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 66% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 2.5 mi of water from one end to the other, 1.2 mi at the beam. It sits in Parry Sound District. Its nearest charted neighbour, North Channel (French River), is 3 mi to the north.
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 5 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
