Compendium on silting of reservoirs in India

The Central Water Commission’s compendium on silting of reservoirs in India in 2015 had shown that Tungabhadra dam was the second most affected dam in the country after the massive Bhakra dam in Punjab. While the last survey of the silt in the dam was conducted in 2008, extrapolation by technical experts based on the high siltation levels in the TB dam (of around 0.5 tmcft a year) pegs the loss in storage at more than 36 tmcft over the past 65 years.
