Depth
4% of Lac aux Grandes Pointes is deeper than 30 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 1978 records a maximum depth of 60.7 m, drawn from 154 depth contours.
