This has been the question in the minds of people across India since Lake Lonar in the state of Maharashtra suddenly changed shades in recent days.
“It looks very red this year because the salinity of the water has increased this year,” he said. “The amount of water in the lake has decreased and the lake has become shallower, so the salinity has increased and caused some internal changes.”
Kharat said researchers are also investigating whether the presence of red algae caused the color to change.
The samples are being sent to several laboratories, he said, and “after studying it, we will be able to say definitively why the lake’s water has turned red.”
