It lies about 3 kilometres ( 2 mi ) west of Esperance and is bounded to the east by the South Coast Highway. Although historically the water in the lake was visibly pink, as at 2017 it has not been pink for over ten years. Contents 1 Description 2 Birds 3 Salt production 4 Misleading name 5 References Description The distinctive colour of the water changes as a result of green alga Dunaliella salina, halobacterium Halobacteria cutirubrum, and / or high concentration of brine prawn. Once the lake water reaches a salinity level greater than that of sea water, the temperature is high enough and adequate light conditions are provided, the alga begins to accumulate the red pigment beta carotene. The pink halobacterium grow in the salt crust at the bottom of the lake. It is believed that the construction of a highway and a rail line altered the flow of water into the lake reducing its salinity which is why ( as at 2017 ) it no longer appears pink. Birds The lake has been identified by BirdLife International as an Important Bird Area because it usually supports significant numbers of hooded plovers and sometimes over 1 % of the world population of banded stilts. It has had many migrant and native birds. Between 1997 and 2006, populations of between 12 and 12,000 of the banded stilt were recorded. There was a population of between 5 and 68 of the hooded plovers from 1995 to 2005. Salt production 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. The company WA Salt Supply produce water softening salt, coarse salt and sheepskin salt at the Esperance site. The salt is kiln dried, crushed and bagged at the site before being distributed. Misleading name Because tourists who visit Esperance to see the Pink Lake are disappointed not to see a pink lake, there have been proposals to either change the name of the lake and the town back to Lake Spencer or to find a way to alter the salinity so that the lake appears pink once again.
