## Vaigai in literature

Sangam literature (circa 300 BCE to 300 CE) has paid many tributes to Vaigai, extolling it as 'the river that brings water when one touches it', viz the etymology Vai (Earth) + yai (sky) = Vaiyai.
The following story is told about the birth of the river Vaigai. Koodal Purana details the origin of Vaigai river flowing through Madurai. It is believed that Vishnu stood up as Trivikrama, with one of his feet rising to the skies and the foot reached Brahmaloka, the abode of Brahma. Brahma was pleased to perform ablution to the raised foot and the water is believed to have emerged as a rivulet called Krithimala. As the river came from the sky and fell into Earth it is called Vai which means Vaiyam (Earth) and Yai means coming down hence, the name Vaiyai and later changed into vaigai. It is mentioned as Vaiyai in Paripatal and not Vaigai. A large number of banana trees sprang up in the place and it came to be known as Kadhalivana, a forest of banana trees.
It also is mentioned as the Sanskrit name Krithamal by a Pandya king in the following story. Satyavrata, a ruler of Madurai was a staunch devotee of Vishnu. It is believed that once Vishnu came out of the river Krithimala as a fish (Matsya avatar, one of the avatars of Vishnu) to teach Vedas to the ruler. From then on, the Pandyas started using fish as the symbol of the kingdom.

## Tributaries

The main tributaries of the Vaigai are Siruliar, Theniar, Varaha Nadi, and Mangalar. Vaigai Dam is the major dam in this river which is present in Theni district.
Vaigai gets major feed from the Periyar Dam in Kumili, Kerala. Water from the Periyar River in Kerala is diverted into the Vaigai River in Tamil Nadu via a tunnel through the Western Ghats. In summers, the Vaigai river ends up dry very often. The water scarcely reaches Madurai.

## Dams

The Vaigai Dam is built across the river in Periyakulam taluk, in the Theni district of Tamil Nadu. It provides water for irrigation for the Theni District, Dindigul District, Madurai district, Sivagangai District, Ramanathapuram District and indirectly serves Virudhunagar District through Irrigation canals from Sivagangai District. It also provides drinking water to Madurai and Andipatti. Near the dam, the Government of Tamil Nadu has constructed an Agricultural Research Station for researching the growing of a variety of crops, including rice, sorghum, blackgram, cowpea and cotton.
The Mullaperiyar Dam was built in 1895 by John Pennycuick, who implemented a plan proposed over a century earlier by Pradani Muthirulappa Pillai of Ramnad. The dam was built by the British Army Engineering corps for the Travancore kingdom. The first dam was washed away by floods, and a second masonry dam was constructed in 1895.
