It has a salinity of 3,000 mg/l, over 40 times as salty as Mono Lake and is the world's saltiest large water body. Almost nothing can survive in this water except highly specialized green algae and red archaeobacteria which are of great scientific interest.
It has a surface area currently of 810 square kilometers, 1/3 smaller than its natural size. It has a depth of 330 meters.
