Depth
14% of Lake Manitou is shallower than 3 m, and 29% is deeper than 20 m.
How to read it: the lake’s area is sorted from the shore to the deepest point. Where the curve is flat, large areas share one depth (flats and weed beds); where it drops, depth changes quickly (drop-offs).
The government depth survey records a maximum depth of 48.8 m, drawn from 122 depth contours.
