Mullaperiyar Dam

Concrete Gravity Dams

 

Overview

Mullaperiyar Dam  is a masonry gravity dam on the Periyar River  in the  state of Kerala, but is operated and maintained by Tamil Nadu state. The water is diverted eastwards to service farmers in Tamil Nadu. The dam is located 2889 feet above mean sea level on the Cardamom Hills of the Western Ghats in Thekkadi, Idukki District in Kerala. 
 
The unique idea of harnessing the westward flowing water of the Periyar river and diverting it to the eastward flowing Vaigai river was first explored in 1789 by Pradani Muthirulappa Pillai, a minister of the Ramnad king Muthuramalinga Sethupathy, who gave it up as he found it to be expensive. The location of the dam had first been scouted by Captain J. L. Caldwell, Madras Engineers in 1808 to reconnoitre the feasibility of providing water from the Periyar river to Madurai by a tunnel through the mountains. Caldwell discovered that the excavation needed would be in excess of 100 feet in depth and the project was abandoned with the comment in his report. 
 
The first attempt at damming the Periyaar with an earthen dam in 1850 was given up due to demands for higher wages by the labour citing unhealthy living conditions.[8] The proposal was resubmitted a number of times and in 1862, Captain J. G. Ryves, M.E., carried out a study and submitted proposals in 1867 for another earthwork dam, 62 feet high. The matter was debated by the Madras Government and the matter further delayed by the terrible famine of 1876-77. Finally, in 1882, the construction of the dam was approved and Major John Pennycuick, M.E., placed in charge to prepare a revised project and estimate which was approved in 1884 by his superiors.
 
It has a height of 53.6 m from the foundation, and a length of 365.7 m .Width (crest) 3.6 m Width (base) 42.2 m.
  
In 1979, safety concerns were raised by the Kerala Government, after an earthquake left cracks and leaks in the dam. The Centre for Earth Science Studies (CESS), Thiruvananthapuram, reported that the dam would not withstand an earthquake above 6 on the Richter Scale- the further cause for concern is that the dam is located in a seismically active zone. In response to this warning, the then Tamil Nadu Government lowered the storage level to the current 136 feet at the request of the Kerala Government, to carry out the safety repair.
 
The Periyar National Park in Thekkady is located around the dam's reservoir.
