Depth
35% of McIntosh Lake is shallower than 3 m, and 27% is deeper than 10 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 1975 records a maximum depth of 27.4 m, drawn from 29 depth contours.
