Depth
20% of Chandos Lake is shallower than 3 m, and 26% 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 from 1961 records a maximum depth of 45.7 m, drawn from 78 depth contours.
