Maharloo Lake, a seasonal salt lake in Iran, is featured in this image captured by the Copernicus Sentinel-2 mission. Maharloo sits at an altitude of around 1,400 meters above sea level and is located around 27 kilometers southeast of Shiraz, in southwest Iran. Yearly evaporation in the desert region is much greater than the yearly rainfall, meaning the lake is often very dry.
Owing to the high evaporation rate, the lake’s bed has been covered by salt over time. This increased salinity in the lake’s waters has allowed certain algae to thrive and cover the surface. The water includes a variety of organisms that display colors ranging from pink to orange to red, with the strength of the color differing in various periods of the year. Usually, the deeper the lake is, the darker the colors of the water.
Given the lake is seasonal, water levels will drop in the summer and rise again in the winter. In this image, the lake appears dark orange, which means that the lake is very shallow but still contains some water.
As is the case with many desert lakes, salt washed down from the surrounding mountains accumulates and can be seen in the image as a white crust along the lake’s shores. In some parts of the lake, facilities have been built for salt extraction (visible in this image along the southern shore).
The lake’s excessive salinity prevents organisms, especially fish, from living in the lake. However, some birds migrate to Maharloo during the summer months, including flamingo. Shiraz, visible in the top-left of the image, is the fourth-most-populous city of Iran. Shiraz International Airport can be seen just south of the city.
