Causeway Separating Lake Urmia into Two Halves, Iran

The northern half of Lake Urmia, in Iran, appears greenish, while the southern half is rusty red in color. The lake is divided into northern and southern parts separated by a causeway, in which a 1500m gap provides little exchange of water between the two parts. The causeway is visible in this image, near the center of the lake. Due to drought and increased demands for agricultural water in the lake’s basin, the salinity of the lake has risen to more than 300 g/L during recent years, and large areas of the lake bed have been desiccated. These dessicated areas appear as white salt flats.
