There is urgent need for publicly known norms of transparency and accountability in operation of reservoirs that are like time bombs that can explode multiple times. Bhakra exploded in 1988, Ukai in Gujarat did in Aug 2006, Hirakud did in Sep 2008, Srisailam, Tungabhadra, Upper Krishna and Damodar dams did in Sep 2009. The wrong operation of Bhakra, Pong and Tehri reservoirs in 2010 lead to avoidable floods in the downstream areas.
