A salt lake or saline lake is a landlocked body of water that has a concentration of salts and other dissolved minerals significantly higher than most lakes. 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.

An endorheic lake is a collection of water within an endorheic basin,or sink,with no evident outlet. Endorheic lakes are generally saline as a result of being unable to get rid of solutes left in the lake by evaporation. These lakes can be used as indicators of anthropogenic change,such as irrigation or climate change,in the areas surrounding them. Lakes with subsurface drainage are considered cryptorheic.
