Pit lakes form when open-cut mining operations cease and the remaining pit fills with ground, surface and rain water. Mine pits, and therefore pit lakes, tend to have high depth-to-surface-area ratios with relatively flat bottoms and steep sides in order to minimise resource extraction costs (n.b., for the purposes of this review we are focussing on large …
