The drive between the Vallakadavu and the Idukki dam along a
stretch of around 40 kilometers through narrow winding roads that passes through
steep hills and valleys is breathtaking. On one side are thick, dense jungles
with tall, ancient trees and evergreen foliage interspersed by colourful
flowering parts and little front yard gardens while on the other is the steep,
deceiving valley of the Periyar. On rainy days, the river unleashes its full
fury with a deafening, constant roar.
Along this beautiful stretch of road lie the villages of
Vandiperiyar, Keerikara, Mlamala, Chappathu, Parappu, Uppukara and Ayyapankoil.
The proponents for constructing a new dam at the Mullaperiyar strongly believe
that if the existing dam breaks, flood waters would gush from the Periyar dam
towards the Idukki dam located more than 40 kilometers downstream the Periyar
wiping away all the villages on its way. Assuming that the Idukki dam is
also full at the time of the collapse of Mullaperiyar, the extra 5 tmc water
would not be withstood by the more modern Idukki arch dam resulting in the
release of 70 tmc of water that could wash a significant portion of the state
of Kerala including some top towns such as Kochi.
