The pink lake

Sometimes during the year Lake Urmia waters turn pink. This curious phenomenon is visible also from space: blue water turn to a pink-red bright colour. This happens during the warmest months of the year and it’s caused by the fact that this Lake is drying up. Urmia lake is infact disappearing, just like the Aral Lake. Lake Urmia, in north-western Iran, was the largest salt-water lake in the Middle East in the ’90s, but in 2008 it shrunk to half the size.

Less water means that the water left is saltier. Beacuse of the water conditions many migratory birds including flamingos, pelicans, ducks and egrets don’t stop here anymore. The desiccation of Lake Urmia is also destroying one of the world’s largest natural habitats of the brine shrimp Artemia, a hardy species that can tolerate water that are eight times more saltier than ocean water. In this Lake, from april to june, the water color changes and turns blood-red because of algae and bacteria that flourish here. The coastline of the Lake, as we can see from space,  is whitish beacuse of the salt that sets down where water completely evaporates.
