Rudkhane-ye-Khoshk, a seasonal river flowing through the city of Shiraz, brings most of the flood water to the lake bed during intensive precipitation events. The lake water typically evaporates by the end of summer and exposes the white lake bed. By mid-summer and due to high evaporation rates and salt concentrations, the lake water turns pinkish red as a result of the red tide within the lake.
