Local residents said that the mysterious deaths of the fish were due to contaminated water from a nearby solid waste management plant run by the Bruhat Bengaluru Mahanagara Palike (BBMP) being released into the lake. Residents said they had informed the Karnataka State Pollution Control Board and expect the officials to come inspect the lake water.

"Similar to last year, thousands of fishes died in Chikkanagamangala lake (Biocon lake) near Electronic City. Mostly due to toxic water entering the lake from near by waste management plant operated by BBMP," wrote X user Electronic City Rising, who shared a video of the macabre visuals at the lake.

However, officials from Bengaluru Solid Waste Management Limited (BSWML) countered, stating, "We installed a leachate-treatment unit at the plant around five months ago, treating 50,000 litres daily. No untreated waste is released, and the treated water is used for tree planting. Any sewage in the lake likely comes from other sources."
