The Elada dam is an important water source for Kotagiri town in the Nilgiris. It has become dry a couple of months back and this prompted us to revisit it and see what has changed, apart from the poor rainfall this year. One easy way to look at changes over time is to use historical imagery from Google Earth. For ease of comparison the imagery from 2008 and 2015 for the Elada catchment has been converted into a time slider using javascript available at

If you note any significant changes in the catchment that you think may influence the water regime, then do leave a mention of it in the comments. We will be posting such time series comparisons and other information about the important wetlands in the Nilgiris in this website.
