 What is happening now, according to local scientists who are studying the phenomena, is that with continuous high water in the lake throughout the year much of this process of 'feeding' on the nutrient in the lakebed had discontinued.The result—the biomass are losing weight and getting thinner by the year.Around January last week in 1999, it was reported that a large chunk of the biomass in the northern part of National Park had broken up into pieces and had drifted freely from the park area.
