Piccaninnie Ponds Deterioration

Piccaninnie Ponds is listed as a wetland of international importance under the Ramsar Convention. It is located in the lower south east of South Australia. Over 110m deep, it is an extraordinary example of a coastal spring, marking the final outflow for the ancient water that flows from the north as part of the unconfined aquifer. Ron and Valerie Taylor filmed 'Pics' in their 1966 classic “The Cave Divers”. Famous underwater photographer David Doubilet captured its beauty for National Geographic in 1984. This video shows images and video taken between 2008 and late 2004. But now Pics is in trouble. It might be considered the canary in the coal mine, one of the early signs of the trouble the wider South East is facing as the water table is dropping. Our drying climate alongside increasing human use of water in this area for agriculture, forestry and even drinking; means that there is simply insufficient water flowing through this sytem to keep it healthy. Increasing water temperature and nutrient loads are both a symptom of the lack of groundwater flow, and a cause of the current algal overgrowth and poor water clarity. A vicious cycle. Like all complex systems there is no easy answer, and no single cause. The caretakers, SA's National Parks and Wildlife Service, are in an impossible position. If they dam up the outlet the levels will rise but the transit time of water through the system will slow - worsening algal growth. If they speed up the water flow through the system, the levels will drop overall exposing more peat and plants to die off. Short of a massive improvement in rainfall at the right time of year, it is hard to see the system recovering any time soon. I think it is time we invested in restoring the aquifer to save not only these natural resources, but the industry and tourism that the area relies on. Let's not wait until there's nothing to drink!
