63-acre lake in Parry Sound District, Ontario. The lake tops out around 47 ft. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 63 acres of water rimmed by 2.9 miles of bank. The 2.6 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 77% of this chart. Call it 0.7 mi long by 0.4 mi wide at the broadest reach. The water lies in Parry Sound District. Closest neighbour on DepthScout: Sugar Bush Lake, 1 mi west of here.
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 10 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring brown bullhead. Time it for after dark and the evening.

|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |

| Fall | 5 to 15 ft | dusk | Back-bay flat (5 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (46 ft) |
