Book Review: Submerged Worlds & Amazing Stories of India’s Mighty Rivers
“All rivers are living entities. The job of any river is to flow. And it flows in a most systematic and sophisticated manner. As it flows, it nurtures everything around it, everything within it.

(Feature Image: Srisailam dam in Telangana. Source: Telangana Today)
The Srisailam, dam one of the biggest dams of India, is facing a serious dam safety issue since over a decade, and yet, strangely, there is no resolution of this in sight. All attempts seem to downplay the issue and hide the reports & reality from public domain. It is well known that the damage to the stilling basin and plunge pool area, part of the Dam project and located just downstream of the main wall is serious and some of the cracks from the downstream are going towards the main dam. Even the National Dam Safety Authority (NDSA) visited the dam a year back, but no action plan is in sight.
