Telangana’s Kaddam Dam, built with inadequate spillway capacity, has seen multiple threats and disasters over the years, starting from the very first year after its commissioning in 1958. The dam again saw threat of being washed away during monsoon this year. The Telangana government has decided to rehabilitate the dam at a cost of Rs 640-700 Cr, by reconstruction of spillway and installation of new gates. We hope the new spillway capacity will be in line with the changed monsoon rainfall pattern and will be able to take care of the higher probable maximum precipitation and higher probable maximum flood. Though we are unlikely to get to know how this is going to happen, as the standard operating procedure of all dam owners in India is secrecy rather than transparency even in dam safety aspects. One also hopes this is done at the earliest, and till that is achieved, the dam rule curve will be changed to ensure the dam does not face disastrous situations during monsoon.
