50-acre lake in Parry Sound District, Ontario. The lake tops out around 50 ft. The depth data here comes from the Ontario MNRF survey of 1974, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Gilbank Lake maps at 50 acres behind 1.7 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. 21% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.6 mi, about 0.3 mi across. It sits in Parry Sound District. Its nearest charted neighbour, Turtle Lake, is 1 mi to the northeast.
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 15 to 50 ft, wintering in 15 to 50 ft.

A blade bait vertical or a small jigging spoon covers the summer program.
