Economic Significance

  • The very name “Kaveri” manifests its significance. “Kaveri” comes from Ka and viri, and means “one who brings abundance where she flows.”.
  • The Kaveri delta is one of South India’s rice bowls and supports 4.4 million people.
  • The Kaveri basin contributes 40% of the food grain in Tamil Nadu and 26% in Karnataka.
  • Asia’s first hydroelectric dam was built across the Kaveri at Shivanasamudra. The dam provides electricity to Bengaluru.

Recent Disasters

In 2016, the Kaveri went dry at its source as rainfall fell by 40-70%. Ironically, Tamil Nadu had suffered some of its worst floods a few months earlier in 2015. Five hundred people lost their lives. Estimates of the damage ranged from INR 20,000-160,000 crores. And a year later in the summer of 2017, once again, Tamil Nadu faced drought – the worst in 140 years, while Karnataka stares at a 36% shortfall in food grain production.

The growing trend of alternating flood-drought cycles is becoming apparent in almost all major rivers in India.

Spiritual & Cultural Significance

The Kaveri’s origins are closely related to Agastyamuni, who is in many ways the source of the spiritual process in the whole of South India.

Many of South India’s sacred spaces are along the Kaveri’s banks. Thiruvanaikaval, the pancha bhuta sthala for water​,​ is along its banks. The linga here is always partially immersed in water.

The Kaveri herself is described as a goddess. For the Kodavas, one of the indigenous people of the Western Ghats, Kaveri is the kula devata or family deity.

One of the oldest dams in the world, the Kallanai dam was built almost 2000 years ago on the Kaveri, by the Chola king Karikalan.

Poompuhar, a town near the place where Kaveri reaches the ocean, was one of the most important ports of the ancient world. Known as Kaveripoompattinam, traders set sail from here to Rome, Greece, China and the Far East.
