In the 1960s-1980s BCC (before climate change), I lived on the edge of Sydney's Narrabeen Lake/Lagoon. It is like a miniature Coorong. Depending on how much rain falls on the catchment, for long periods it is open to the sea (Narrabeen Lagoon) and at other times the mouth is blocked by a sand bar (Narrabeen Lake). There were often cries from locals with opposing views on whether it was better to be a saltwater lagoon, or a freshwater lake. Sometimes the salties won and bulldozers fiddled with nature in dry times, by cutting a channel through the sand spit to let the sea in. Other times the freshies won because there was not enough flow to keep the channel open. During the change-over periods, there was a terrible stench that came from the salt-fresh interface caused by zillions of dying organisms failing to cope with the changes to their environment. Nature is a wonderful thing — as long as you don't try and change it too much.
