Depth
42% of Tee Lake is shallower than 3 m, and 35% 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 records a maximum depth of 12.2 m, drawn from 6 depth contours.
