What is the salinity percentage in Lake Eyre in Australia?
The salinity of Lake Eyre is increasing, and has changed dramatically over time. It was sampled in July 1974, and the minimum salinity value at that time was determined as 7%, and again in April 1975, when the salinity level was determined to be 40%. However, the percentage of salinity also seems to be seasonal. AsLake Eyre is currently full (May 2009), salinity levels are lower than they were prior to the wet season – but this is not always the case. When the floodwaters come from monsoonal rains in north Queensland, salinity levels are initially lower, but the problem is that, with the water flow, more saline is discharged from the Murray-Darling basin groundwaters, thereby oncreasing the salt content of Lake Eyre and the other salt lakes of inland Australia.
