What’s happening to Bengaluru’s lakes?

A chronological tracker of developments related to Bangalore's lakes.

Feb 2013

The poor rainfall of the past year has resulted in several dry lakes in the city. Speaking to Bangalore Mirror, environment and lake expert Dr Yellappa Reddy explained why lakes were drying up: "All of us are aware that the monsoons failed this time and there is hardly any inflow of water to the lakes. However, lakes situated inside and adjacent to urban localities could have maintained the inflow with recycled water."

The lake beds of Dasarahalli Lake and Herohalli Lake have completely dried up. There are only traces of water at Hebbal and Kengeri Lakes. Water levels at Sankey Tank and Ulsoor Lake have also gone down owing to lack of inflow. Fishermen who obtained contracts to fish in these lakes have stopped fishing due to insufficient water levels.
