River Cauvery EN.png

The Kaveri, also rendered as Cauvery, is a large south Indian river flowing through the states of Karnataka and Tamil Nadu. It is the third largest after Godavari and Krishna in south india and the largest in Tamilnadu which on its course, bisects the state into North and South. Originating in the foothills of Western Ghats at Talakaveri, Kodagu in Karnataka it flows generally south and east through Karnataka and Tamil Nadu and across the southern Deccan plateau through the southeastern lowlands, emptying into the Bay of Bengal through two principal mouths in Poompuhar, Tamil Nadu.

The Kaveri basin is estimated to be 81,155 square kilometres (31,334 sq mi) with many tributaries including Harangi, Hemavati, Kabini, Bhavani, Arkavathy, Lakshmana Tirtha, Noyyal and Amaravati. The river's basin covers three states and a Union Territory as follows: Tamil Nadu, 43,856 square kilometres (16,933 sq mi); Karnataka, 34,273 square kilometres (13,233 sq mi); Kerala, 2,866 square kilometres (1,107 sq mi), and Puducherry, 160 square kilometres (62 sq mi).[4] Rising in southwestern Karnataka, it flows southeast some 800 kilometres (500 mi) to enter the Bay of Bengal. In Mandya district it forms the island of Shivanasamudra, on either side of which are the scenic Shivanasamudra Falls that descend about 100 metres (330 ft).[5] The river is the source for an extensive irrigation system and for hydroelectric power.[6] The river has supported irrigated agriculture for centuries and served as the lifeblood of the ancient kingdoms and modern cities of South India.

River course[edit]

After the river leaves the Kodagu hills and flows onto the Deccan plateau, it forms two islands in mandya district's Srirangapatna and Shivanasamudra. First, comes the Srirangapatna which forms the sangam and then comes Shivanasamudra. At Shivanasamudra the river drops 98 metres (320 ft), forming the famous Shivanasamudra Falls known separately as Gagana Chukki and Bhara Chukki.[7] Asia's first hydroelectric plant (built in 1902) was on the left falls and supplied power to the city of Bangalore.

In its course through Karnataka, the channel is interrupted by 12 "anekattu" (dams) for the purpose of irrigation. From the Anekattu at Madadkatte, an artificial channel is diverted at a distance of 116 kilometres (72 mi), irrigating an area of 4,000 hectares (10,000 acres), and ultimately bringing its water supply to the town of Mandya.

Three kilometres away from Srirangapatna, the Kaveri is the basis for the Ranganthittu Bird Sanctuary. Near Srirangapatna is also an aqueduct, the Bangara Doddi Nala, which was constructed in the 17th century by the Wodeyar maharaja of Mysore, Ranadhira Kantirava, in memory of his favourite consort. It is said to be the only aqueduct where the water from a river, dammed upstream, is carried by the aqueduct over the very same river few miles downstream[citation needed]. This aqueduct also served as a motorable bridge until 1964.The kabini river tributary of Cauvery joins Cauvery at Tirumakudal Narasipura where triveni sangama takesplace along with mythological river Spatika. The Moyar River is an east flowing river originates in the Mudumalai, Bandipur, and Wayanad National Parks draining the Nilgiri Hills in Tamil Nadu and Karnataka and is one of the tributaries to the Kaveri River.

The river enters Tamil Nadu through Dharmapuri district leading to the flat plains where it meanders. It drops into the Hogenakkal Falls just before it arrives in the town of Hogenakkal in Tamil Nadu. The three minor tributaries, Palar, Chinnar and Thoppar enter into the Kaveri on her course, above Stanley Reservoir in Mettur, where the dam has been constructed. It then flows further through the length of Erode district where the river Bhavani, running through the breadth of the district, merges with it. The confluence of the rivers Kaveri, Bhavani and Akash Ganga (mythological) is at the exact place of Bhavani, Tamil Nadu Kooduthurai or Tiriveni Sangamam, Northern part of Erode City.

While passing through Erode, two more tributaries merge. Thirumani Mutharu joins it in a village called Kududurai in Namakkal District. Noyyal and Amaravathi join it in Karur district before it reaches Tiruchirapalli district. Here the river becomes wide, with a sandy bed, and flows in an eastern direction until it splits into two at upper Anicut about 14 kilometres (9 mi) west of Tiruchirappalli. The northern branch of the river is called the Kollidam while the southern branch retains the name Kaveri and then goes directly eastwards into Thanjavur District. These two rivers join again and form the Srirangam island that is a part of the city of Tiruchirapalli. The fourth oldest functional dam[8]Grand Anicut or Kallanai was present at this place. From Thanjavur, the river splits and goes to few places in the Delta Kaveri.



The primary uses of Kaveri is providing water for irrigation, water for household consumption and the generation of electricity.

An estimate at the time of the first Five Year Plan puts the total flow of the Kaveri at 15 cubic kilometres (12,000,000 acre⋅ft), of which 60 percent was used for irrigation. [9]

The Torekadanahalli pumpstation sends 540 million litres (19,000,000 cu ft) per day of water from Kaveri 100 kilometres (62 mi) to Bangalore.[10][11]

Stanley Reservoir formed by Mettur Dam, the largest dam in Tamil Nadu

The water for the Kaveri is primarily supplied by monsoon rains. Dams, such as the Krishna Raja Sagara Dam, Mettur Dam, and those on its tributaries such as Gorur dam, Harangi dam, Kabini dam, Amaravati dam and Banasura Sagar Dam store water from monsoon periods and release the water during the dry months. Even so, during the months of February–May, water levels are often quite low, and some channels and distributaries riverbeds may become dry.[citation needed] Flow generally begins to increase in June or July[citation needed]. However, in some years when rains are light, the low river level can lead to agricultural distress in areas dependent upon the Kaveri for irrigation.[citation needed]

The hydroelectric plant built on the left of Sivanasamudra Falls on the Kaveri in 1902 was the first hydroelectric plant in Asia.[5]

The Krishna Raja Sagara Dam has a capacity of 49 tmc ft.[12] and the Mettur Dam which creates Stanley Reservoir has a capacity of 93.4 tmc ft. (thousand million cubic ft)

In August 2003, inflow into reservoirs in Karnataka was at a 29-year low, with a 58% shortfall.[13] Water stored in Krishna Raja Sagara amounted to only 4.6 tmc ft.[13]

Water sharing[edit]

Significance in Hinduism[edit]

There are several legends about how the river Kaveri came into being. Chapters 11–14 of the Skand Puran (also known as the Kaveri Puran) relate many of them. According to the most well known version, when the great ocean was churned by the Dev and the Asur in order to obtain Amrit, the elixir(Ambrosia), Lord Vishnu turned into Mohini, a non-pareil of infinite charm and appeal, to distract the Asur and restore Amrit to the Dev. Devi Lakshmi also sent along Lopamudre, an Apsara to assist Mohini. After the Amrit was successfully restored to the Dev, Lopamudre was brought up by Brahma as his daughter.

After some time Kaver, a sage of renown, came to Brahmagiri to meditate. Kaver was lonely and prayed to Lord Brahma that he might bless him with a child. Brahm was pleased by his devotion and gave him Lopamudre for a daughter. Lopamudre was renamed Kaveri after the sage.

Kaveri was very keen that her father should have every happiness and prosperity in life and a blessed land full of good and happy people. So she went to the Brahmagiri too and prayed to Lord Brahm that she might turn into a river and flow through the country, pouring her blessings on the people and turning the land green and fertile. She also prayed that her waters might be so holy that all those who took a dip in it might be absolved of all their sins. Brahm granted her both the boons readily and Kaveri was really happy.

But something else was to happen to her first. Sage Agastya happened to see Kaveri when she was deep in meditation on the Brahmagiri. He fell in love with her and asked her to marry him. Although her heart was set on turning into a river of blessings, Kaveri could not refuse Agastya. But she made him promise that if ever he left her alone too long, she would have the right to forsake him and go her way. Agastya promised and kept his word faithfully for some time. But one day he got busy in a theological discussion with his disciples and lost track of time. Kaveri waited patiently for a while but after some hours had passed she jumped into Agastya’s special holy tank and flowed from it like a river. As soon as the disciples of Agastya saw what had happened they tried to stop her from flowing away. But Kaveri promptly went underground and appeared again at Bhagand Kshetr and flowed on toward Valambari and finally into the Bay of Bengal. And it has been worshipped as a sacred river – throughout its course – ever since.

There is yet another interesting belief according to which the river Ganga also joins Kaveri underground once a year, during the Tulamaas, in order to wash herself free of the pollution caused by the crowds of sinners who bathe in her waters all the year round. Kaveri is considered to be as sacred as the Ganga throughout its course, with the same power to wash off all one’s sins. But Bhagamandal, where the three rivers meet, is considered to be the most sacred spot of all. There are Mandir all along its banks visited by thousands of pilgrims. Kaveri is joined by several rivers, the most important ones being Kummahole, Hemavati, Lakshmantirth, Shimsha etc., it flows into the Bay of Bengal in Thanjavoore district in Tamil Nadu.

During the month of Tula, devotees take holy dip (Tula Snan) in the Cauvery in the pilgrim centers in its banks across the two states of Karnataka and Tamil Nadu, most prominent of them being Bhagamandala in Karnataka and Mayavaram in Tamil Nadu. The cult of the river Goddess began in Kodagu and was centered in Bhagand Kshetr (Bhagamandala).

The three major river islands at Kaveri have a strong Vaishnav heritage, with sculptures of Lord Vishnu in a reclining posture on the legendary seven-headed serpent (Sesh Nag) as his celestial bed (Shesh Shayan). These three temples are known as Adi Ranga, Madhya Ranga, and Antya Ranga.

On the banks of the Kaveri is the ancient temple town of Talakadu where the holy festival Panchalinga Darshana is held every 12 years and devotees bathe in the Kaveri River.[14]

Prominent towns, religious sites[edit]

Veneration as a Devi[edit]

The river is revered as Goddess and an exclusive day is observed as Aadi Perukku where Cauvery is celebrated with offerings.

The legend of Kaveri has its origins in Puranam. Kaveri is directly linked with three icons of the Puran[16] i.e. Agastya, King Kaver and Lopamudra, the earthly, feminine manifestation of Kaveri herself. It is held that Lopamudra was granted the form of a river, by Brahma, in answer to Tapas performed by all the three, including herself.

Both the sant (saints) Agastya and King Kaver were independently performing Tapas with salvation (Moksh) as the goal. Pleased by their Tapas, Brahma appeared before them but only to deny both immediate Moksh. Instead, Brahm instructed Kaver that he will beget a daughter who will lead him to Moksh; to Agastya, Brahm gave a divine wife; Agastya was instructed to live with her and enrich the world, before eventually attaining Moksh. In the meantime it was said that Vishnumaya, the divine daughter of Brahm—the impeccable feminine creation of the creator, expressed to Brahm her wish to serve the world. Being pleased, Brahm ordain her to be, in due time, Lopamudra, the daughter of Kaver, then the wife of Agastya, and eventually the sacred of the sacred, the river Kaveri.

In a slightly different version, Kaveri is regarded as the outpouring of sage Agastya's Kamandal; it is said the Lord Ganesh, assuming the form of a crow, upset Agastya's Kamandal to release the Kaveri.

After assuming the form river, Kaveri performed another Tap to become the sacred of rivers. Her Tap was answered and Lord Vishnu appeared before her. On hearing her wish, Lord Vishnu said, "Ganga is sacred because she originates from my feet; but you are infinitely more sacred to her as I adorn you as my garland". Upon this blessing, it is said that even the Ganga is said to come underground, once a year, to Kaveri to cleanse herself. To this day, the Vaishnavite regard Kaveri, the river that holds Srirangam in her bosom, as the most sacred of rivers. Vaishnavaite lovingly regard Kaveri as the mother of Ranganayaki, the divine consort of Lord Ranganath of Srirangam in Tiruchirappalli.
