Palar River is a rain fed river of southern India, rises in Nandi Hills
and passes through Kolar district
. It flows at about 93 km in Karnataka, 33 km in Andhra Pradesh
and 222 km in Tamil Nadu before its confluence into the Bay of Bengal
at Vayalur about 100 km south of Chennai
Palar River flows as a "Guptagamini" (underground course) for a long distance only to emerge near Bethamangala town, from where, gathering water and speed, it flows eastward down the Deccan Plateau
The cities of Ramanaickenpet, Vaniyambadi
, Ambur, Vellore, Melvisharam
, Walajapet (Anaicut), Kanchipuram, and Chingleput are located on banks of Palar River. Palar River has seven tributaries and the chief tributary is Cheyyar River
The average rainfall in entire Palar river basin is low. This river basin used to suffer from frequent droughts. However, Karnataka and Tamil Nadu have mitigated frequent recurrence of droughts by developing innumerable minor and medium irrigation tanks. This has improved the availability of water for surface as well as ground water irrigations. As per the wet land atlas of India, the manmade wet lands are covering extensive area (3% to 5%) in the districts of Karnataka and Tamil Nadu covering Palar river basin. Whereas the Palar basin in Andhra Pradesh is not well covered by wet lands, which implies that the river water usage in Andhra Pradesh is not up to the mark, compared to Karnataka and Tamil Nadu.
Palar River is so important for irrigation in the north and south Arcot districts of Tamil Nadu, but it flows a meagre of 50 km in Andhra Pradesh, the Palar River had been seen dry for almost 20 years. Palar River has been abode for mud robbery and other illegal activities.
