Submitted by Editor on Tue, 2016-05-10 20:50 Bengaluru: Huge quantities of dead fish were seen floating in the Ulsoor Lake on Tuesday, underscoring once again that nothing has changed in the lake even after hue and cry among officials and activists over the fish deaths which occurred in March. G Tirumurthy, senior environmental engineer, Central Pollution Control Board, inspected the lake and collected water samples. “There is no doubt that the water is polluted as the DO level has crashed. The pollution is because of garbage and sewage inflow into the lake. The State authorities have already initiated steps and constructed the retaining wall to arrest the floating materials into the lakes. We will do periodical checkup send the reports to Ministry of Environment and Ecology,” he said. Since the fish deaths in March, authorities have done very little to contain the inflow of sewage into the lake, said activists, who said that sewage inflow was the primary reason for fish deaths. “Authorities are just playing the blame game. It is the matter of clearing the garbage after heavy rains. Had the BBMP cleared garbage and stopped the sewage, fish deaths could have been prevented,” said urban conservationist Vijay Nishanth. Hema H, a resident from Ulsoor who noticed the fish deaths, said the public continued to dump garbage in the storm-water drain and were equally responsible for the deaths. “Every time it rains, garbage flows into lake. The BBMP should depute a guard near the storm-water drain that connects the lake as this will prevent people from throwing waste,” she said. Ravi, Bharathi Nagar resident, said he could not walk due to the foul smell. “We could not walk as there was bad smell emanating from the lake. As expected, the smell was coming from dead fish,” he said. Venkatesh, Assistant Executive Engineer, BBMP, said the civic body was only responsible for maintenance of lake and could not control the commercialization of the lake which, he said, could also be responsible for the fish deaths. “The lake has a capacity of about 80,000 fish but with an eye on business, the contractor let more than 1 lakh fish into the lake. This is another reason for the depletion of oxygen level in lake,” said Venkatesh. Deputy Director Fisheries Veeranna Gowda and Chief Engineer for waste water management Ramakrishna were not available for comment.
