I went with my family to nana devi and this dam was on the way .i was so stunned after viewing this fan .The man there told that there are 5 turbines that rotate to generate electricity from falling water and he also told the dam is so big that if it breaks its water has a capability to submerge whole punjab even delhi and some parts of pakistan .There is boting also .The place is too silent it feels like you are im heaven .It was also written that. When dam wS build it submerged 356 villages .It was a memorable day and I enjoyed alot with my family . : )
