The Mysore City Corporation authorities were summoned immediately and repair of the UGD line was taken up.
It was observed that the dead fish was collected the dead fish were being collected and loaded on to boats by lake employees to be buried nearby. However, the lake authorities expressed fear that other animals that have consumed the dead fish especially birds, may be affected.
Lake officials said, to avert such an incident, they had been putting chemicals in to the lake that minimise the organic load of contaminants. However, the sudden downpour over the last two days might have damaged the UGD line letting in sewage water in huge proportion increasing the contamination of water which turned fatal for the fish. The official also said water samples from various points in the lake have been collected for checking the level of contamination.
