Mass fish deaths reported in Bengaluru's Doddagubbi Lake after polluted runoff
Thousands of fish have been found dead in Doddagubbi Lake in Bengaluru after rainwater mixed with polluted runoff, prompting officials to test the water.
In Bengaluru's Mahadevapura Assembly constituency, Doddagubbi Lake, covering about 125 acres, experienced a massive fish kill after recent rains introduced polluted water into the lake. Officials attribute the deaths to oxygen depletion, likely caused by runoff from the Mittaganahalli GBA dumping yard mixing with rainwater. Deputy director B Chikkanna of the Fisheries Department and K S Sudhakar of the Karnataka State Pollution Control Board have taken water samples for lab testing to determine the contamination level.
The Karnataka State Pollution Control Board described the lake as heavily polluted and unsuitable for any use. Bengaluru Development Minister Krishna Byre Gowda has directed a thorough inspection and remedial measures. Environmental activists point to possible sewage inflow, noting that untreated sewage can rapidly consume dissolved oxygen, a view echoed by former KSPCB chairman Dr Sharath Chandra. The final cause will be confirmed after laboratory results are received.
