#Discovery #PinkLake is a salt lake in the Goldfields-Esperance region of Western Australia. The lake is not always pink but the distinctive colour of the water changes as a result of green alga Dunaliella salina, halobacterium Halobacteria cutirubrum, and high concentration of brine prawn. The pink halobacterium grow in the salt crust at the bottom of the lake and the colour of the lake is a result of the balance between, D. salina and H. cutirubrum. The pink lake is prior to salt production the lake's environment was investigated in the 1980s. Table salt is produced in solar ponds at the eastern end of the lake.
