Depth
46% of Lac des Îlets is shallower than 3 m, and 30% 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 1969 records a maximum depth of 10.1 m, drawn from 6 depth contours.
