A look at 6 Indian dams that are stuck at the gates
1/7
Temghar dam
The constant clackety droning of drilling machines and excavators punctures the idyllic surrounds of the Temghar dam, some 50 km west of Pune. Opened in 2010, the dam, with a capacity of 3,000 million cubic feet, was a key supplement to the ever-thirsty and fastgrowing Pune city and district.
The Rs 314 crore reservoir is empty. It has been drained to facilitate a Rs 100 crore repair for a dam that leaks 10-12% of its contents due to poor construction.
The leaky Temghar dam has been problematic since its opening, with leaks springing up rapidly and the state being forced to blacklist its contractors and rush repairs.
Let's take a look at the other dams that are facing trouble:
