It is a crying shame that Mysore University, which has access to the science of harmful impact of de-silting, is bent upon carrying out the process at Kukkarahalli Lake despite protests by the environmentalists. It is difficult to find any expert who would support desilting given the limited technical ability to de-silt without harming the lake. Authorities have not showed any study to show how de-silting will help the Lake.
Those who believe in the positive effect of de-silting may be influenced by the need to de-silt dams or river bed to store more water. But a lake bed is entirely different. In the former there is continuous flow of water. But it is not the case with Kukkarahalli Lake. One cannot remember when there was overflow there. It is true there are some lakes where de-silting (in 2013, Beed district of Maharashtra succeeded in improving water supply when dried up lakes were desilted) has been beneficial. As shown here, Kukkarahalli Lake does not meet any of the criterion for de-silting suggested by the experts.
