Lake St. Lucia

Italy

Lake St Lucia (also Lake Saint Lucia) is an estuarine lake system in northern KwaZulu-Natal, South Africa. It is the largest estuarine lake in Africa and in Southern Africa, covering an area of approximately 325–350 km2 (125–135 sq mi) and accounting for roughly 80% of KwaZulu-Natal's total estuarin

e area. The lake forms the central feature of the iSimangaliso Wetland Park, South Africa's first UNESCO World Heritage Site, which was inscribed in December 1999, and it has been designated a Ramsar Wetland of International Importance since 1986. The lake system is noted for its extreme environmental variability. Salinity levels fluctuate from near-freshwater conditions to more than 200 parts per thousand (ppt), nearly six times the salinity of seawater, making Lake St Lucia a global reference system for estuarine research. More than 60 years of peer-reviewed scientific research culminated in the 2013 Cambridge University Press monograph Ecology and Conservation of Estuarine Ecosystems: Lake St Lucia as a Global Model.
