"SCIENTISTS have identified a unique Australian lake which has been untouched by climate change and appears to be in the same condition as it was 7500 years ago. Blue Lake, one of the largest lakes on North Stradbroke Island, off the south Queensland coast, has been the focus of a project by University of Adelaide researchers. They studied the lake's water discharge, water quality and comparisons of historical photos over 117 years, as well as fossil pollen and algae, to understand its history over thousands of years. The results, published online in the journal Freshwater Biology, show the lake has remained relatively stable and resilient for millennia. The study's lead author Cameron Barr says Blue Lake is more than 10 metres deep but is so clear you can see to the bottom."
