The main river of Tamil Nadu is Kaveri which originates in Kodagu district of Karnataka. Kaveri and its tributaries in its lower coursen drain the districts of Nagapattinam, Thanjavur, Thiruvarur and Tiruchirapalli. The Kaveri, the Kollidam and the Vellar jointly drain central part of the Tamil Nadu.

River Kollidam branches off from Kaveri at Grand Anaicut (Kallanai).

The Tamil Nadu plain stretches for 675 km from Pulicat lake to Kanyakumari along the coast of Tamil Nadu. Its average width is 100 km. The most important feature of this plain is the Cauvery delta where the plain is 130 km wide. The fertile soil and large scale irrigation facilities have made the Cauvery delta the granary of South India.

The river plains in Tamil Nadu are formed by the river Palar, Cheyyar, Pennar and Vellar in the north; Kaveri and its tributaries in the central region; Vaigai, Vaippar and Thamirabarani in the south.

The head of the Kaveri delta is near the island of Srirangam.
