Salt lake

One of two salt lakes in the northern end of the Danakil Depression known as Lake Karum

A salt lake or saline lake is a landlocked body of water that has a concentration of salts (typically sodium chloride) and other dissolved minerals significantly higher than most lakes (often defined as at least three grams of salt per liter).[1] In some cases, salt lakes have a higher concentration of salt than sea water; such lakes can also be termed hypersaline lake, and may also be pink lakes on account of their color. An alkalic salt lake that has a high content of carbonate is sometimes termed a soda lake.[2]

One saline lake classification differentiates between:

  • subsaline: 0.5–3‰ (0.05-0.3%)[2]
  • hyposaline: 3–20‰ (0.3-2%)[2]
  • mesosaline: 20–50‰ (2-5%)[2]
  • hypersaline: greater than 50‰ (5%)[2]
  • Large saline lakes make up 44% of the volume and 23% of the area of lakes worldwide[2]
