The dissolved oxygen level came down in the lake due to increase of "organic load" following release of sewerage water into the lake that resulted in the mass death, the official said based on preliminary examination. About 1.5 tonnes of fish were found dead on the banks of the water body, the officials said. Kerala: Hundreds of Dead Fish Found Floating in Periyar River in Ernakulam, Video Surfaces.
