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 litre). In some cases, salt lakes have a higher concentration of salt than sea water, such lakes can also be termed hypersaline lakes. An alkalic salt lake that has a high content of carbonate is sometimes termed a soda lake.
