Vaman Achrya, former chairman of the Karnataka State Pollution Control Board, told the News Minute, that the fish die to the decreased oxygen levels in the waters. This happens due to excessive dumping of sewage and waste waters into the lakes. Ulsoor lake in particular is the end point of intreated sewage waters from the areas between MG Road and Indiranagar. “It is the responsibility of the BWSSB, which handles Bengaluru’s sewage and the BBMP, which owns the lake, to set up a sewage treatment plant in the area and ensure that it is treated,” Acharya told TNM.

Acharya also said that when he was the chairman efforts were being made to increase the oxygen levels in the lake, by the release of bacterial cultures. The report also says that the lake is 108 acres in area and has two islands. Although it is a famous haunt of joggers and strollers, it is also notorious for being polluted and garbage can be seen floating on its surface, which also causes the lake to stink up. Pollution by garbage had increased so much that in 2015, 32 trucks of garbage was cleared from the lake!

This comes just months after toxic froth had taken over the city’s streets due to extreme levels of pollution in the largest lake of the city-Bellandur Lake. The lake which lies to the southeast of the city of Bangalore, is also a part of the city’s drainage system and drains the southern and the south eastern parts of the city. The periodic water sampling of the lake waters had revealed extremely  high amount of phosphorous and other inorganic chemical compounds.
