Depth

68% of White Otter Lake is shallower than 3 m, and 17% is deeper than 5 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 from 1970 records a maximum depth of 9.1 m, drawn from 23 depth contours.
