A crystal clear lake that appears totally unaffected by climate change has been dubbed "God's bathtub" by an Australian scientists who studied the body of water.
Blue Lake, on North Stradbroke Island off the south Queensland coast in Australia, has managed to dodge climate change and any man-made influences for 7,500 years, scientists at the University of Adelaide found.
"It appears that Blue Lake has been an important climate 'refuge' for the freshwater biota of the region, and is in the same condition now as it was 7,500 years ago," Cameron Barr, the study's lead author, told the Australian Associated Press. "With appropriate management, the lake could continue relatively unchanged for hundreds, possibly thousands of years to come."

Through a study of the lake's water discharge, water quality, fossil pollen, and algae, researchers found that the body of water has remained in pristine condition for millennia.
"It's like God's bathtub," Barr said. "It is beautiful. It is absolutely beautiful."
Even though Blue Lake is more than 30 feet deep, you can see through the surface straight through to the bottom, the researchers wrote in the journal Freshwater Biology.
Other lakes in the surrounding area have shown evidence of a change in size, shape, or chemistry. Some have even dried up in the last 40 years due to climate change.
Barr believes "God's bathtub" has remained so pure because its waters are constantly draining into a nearby swamp

"Because it's constantly being updated it doesn't suffer from the vagaries of the climate in so far as it doesn't evaporate and become more saline," he told the Australian Broadcasting Corporation. "It doesn't fill up and become fresher. It just remains constant."
