According to reports, the representative also said that the oxygen level one meter below Lonar Lake’s surface is 0%. He further added that the water level in this crater lake has been low for the past few years and there has been no downpour to increase it. He also said that low water levels might have increased salinity and change in algae because of certain atmospheric changes.

Another researcher working at the Babasaheb Ambedkar Marathwada University said that it could be a biological change in the river. He further added that seasonal change takes place in river water and that may be the case with Lonar Lake. Not much is known about the sudden change in color. Although, additional studies and reports are expected after the current global health crisis blows off.
