Thousands of dead fish washed up on the banks of a polluted lake on Monday in India’s southern technology hub of Bangalore.
A stink pervaded the air in a residential district around Ulsoor Lake, in the centre of the city.
Sewage from all over the city has been flowing into the lake and mixing with fresh water said V. Purushottam, president of a local residents’ group.
Purshottam said a barrier, or bund, that was supposed to keep sewage from flowing into the lake had broken, and that authorities had ignored earlier pleas to repair it.
The lake is a popular fishing and boating site, but it has been affected by a large volume of water hyacinth growing on its surface.
It is not the first time Bangalore’s lakes have illustrated the high levels of pollution present under the surface.
Last year, a toxic froth spilled onto some of the city’s streets due to extreme levels of pollution in Bellandur Lake, while flames were seen in another polluted lake in the city, Indian newspapers reported.
The water sampling of the lake waters revealed extremely high amounts of phosphorous and other inorganic chemical compounds, the reports said.
