Depth
69% of Irish Lake is shallower than 3 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 2007 records a maximum depth of 6 m, drawn from 55 depth contours.
