With rains affecting Bengaluru and parts of the city receiving the highest rainfall in a day in August in several years, Bellandur lake continued to spill thick toxic foam.

'Toxic foam' allegedly due to discharge of sewage water engulfed large partof the Bellandur Lake.

The residents have also started complaining of foul smell and pollution.

Highly polluted Bellandur Lake, the largest of the 262 lakes and tanks in Bengaluru, has spilled toxic foam many times in the recent past and on several occasions the toxic foam also caught fire.

The sorry state of the lake forced the National Green Tribunal (NGT) to take the matter suo motto.

"This foam problem has been there for a very long time. Due to heavy rain for past two days, the water level has increased and now the foam has overloaded the whole bridge. Because of this, it is difficult for commuters to drive on the road. The residents are also trying hard to solve this matter," a local resident Jitesh told ANI.

The commuters were not able drive due to the intense foam, giving them a tough time.

On April 19, the NGT directed immediate and complete shutdown of 76 polluting industries around the lake after a mound of garbage was set on fire in February this year leading to massive pollution in the area.

Rains from Monday night to Tuesday morning flooded major roads and drainage water entered houses in low-lying areas.

The city was battered by 12.8 cm rain in five hours from Monday night to Tuesday morning, which is stated to be the highest rainfall in a day in August since 1890.

The worst hit was south and eastern parts of Bengaluru-- Koramangala, HSR Layout, Ejipura, Jayanagar, JP Nagar, BTM Layout, Bannerghatta Road and pockets of Indiranagar, where pre-dawn rain and winds snapped power lines, uprooting trees and flooding streets, submerging vehicles.
