Serene reflections - a parody. Here is water storage, in a commonplace dam, excavated on a country property.
More good news. Much of our low lying coastal lands have acid sulphate soils and care needs to be taken if the soil is disturbed by digging etc because, I think, it causes water and acid to develope and create problems. Strangly, as a result, some nice ponds of extraordinarily clear water are not good at all but are abnormal. Perhaps thats counter-intuitive. The ecology is in delicate balance.
