This saline lake is known for its pink colour on clear windy days, caused by Dunaliella salina algae, and its high salt content, up to 40% in some areas.
Due to high precipitations in 2022 and increasing urbanisation, the lake and multiple areas around it have been flooded for months, endangering local economy.
- Its depth rose from 2-3 m to 6 m, decreasing its salt content. It caused a colour change troublesome for the touristic industry. Furthermore, most coastal infrastructures that have been affected were dedicated to tourism.
- 7000 T of already mined salt worth $235 000 has been lost. 3000 workers will lose their job if the salt remains inaccessible with the traditional technique.
