Lake Magadi is classified as a soda lake because its bed consists almost entirely of solid or semisolid soda, and it is fed by streams and springs that are heavily impregnated with sodium carbonate (natron). The primary source of this sodium carbonate appears to be alkaline waters of deep-seated origin.12
The lake, located in the Great Rift Valley of southern Kenya, features a caked crust through which soda water gushes, often dyeing the surrounding waters a vivid pink. Unlike freshwater lakes, which typically have outlets, Lake Magadi is characterized by its high alkalinity and salinity, a common trait among many lakes in the Eastern Rift.12
