AQUAGUIDE POND MANAGEMENT SERIES What is it? Turnover is the gentle, natural mixing of pond and lake waters.It is caused by changing temperatures in surface watersbrought on by the progression of the seasons. In Missouriâscontinental-temperate climate, most ponds and lakes turn overin both the fall and the spring.
A variation is the hot lahar ordinarily produced by the heating of the crater lake water by the quiet upwelling of lava or an explosion. Lahars move downslope at very high speeds and may extend for tens of miles. A lahar deposit usually has a hummocky or hilly surface. They often cause much death and destruction, as at Herculaneum during the eruption of Vesuvius in ad 79.
