A sample study of the water collected by the Karnataka Pollution Control Board (KPCB) at the Mallathalli Lake on Saturday has revealed low Dissolved Oxygen levels (DO).
Out of the four samples collected by KPCB at different corners of the lake, where a lakh fish had died, two samples were found to contain 2.5- 2.8 milligrams of DO, which is unsuitable for the fish to survive.
