It is the third largest after Godavari and Krishna in south India and the largest in Tamil Nadu 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. Amongst the river valleys, the Kaveri delta forms one of the most fertile regions in the country. The Kaveri basin is estimated to be {{convert|81155|km2|mi2}} with many tributaries including Harangi, Hemavati, Kabini, Bhavani, Arkavathy, Lakshmana Tirtha, Noyyal and Arkavati. The river's basin covers three states and a Union Territory as follows: Tamil Nadu, {{convert|43856|km2|mi2}}; Karnataka, {{convert|34273|km2|mi2}}; Kerala, {{convert|2866|km2|mi2}}, and Puducherry, {{convert|160|km2|mi2}}.[3] Rising in southwestern Karnataka, it flows southeast some {{convert|800|km|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 {{convert|100|m|ft}}.[4] The river is the source for an extensive irrigation system and for hydroelectric power.[5] The river has supported irrigated agriculture for centuries and served as the lifeblood of the ancient kingdoms and modern cities of South India. Access to the river's waters has pitted Indian states against each other for decades. River courseAfter 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 {{convert|320|ft|m|order=flip}}, forming the famous Shivanasamudra Falls known separately as Gagana Chukki and Bhara Chukki.[6] 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 "anaikattu" (dams) for the purpose of irrigation. From the Anaikattu at Madadkatte, an artificial channel is diverted at a distance of {{convert|72|mi|km|order=flip}}, irrigating an area of {{convert|10000|acre|ha|order=flip}}, 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|date=February 2007}}. This aqueduct also served as a motorable bridge until 1964.The kabini river tributary of Kaveri joins Kaveri 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 {{convert|14|km|mi|0}} 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 oldest functional dam[7]Grand Anicut or Kallanai was present at this place. From Thanjavur, the river splits and goes to few places in the Delta Kaveri. Tributaries
IrrigationThe 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 {{convert|12000000|acre.ft|km3|order=flip}}, of which 60 percent was used for irrigation. [8]The Torekadanahalli pumpstation sends {{convert|540|e6l|cuft}} per day of water from Kaveri {{convert|100|km|mi}} to Bangalore.[9][10] The hydroelectric plant built on the left of Sivanasamudra Falls on the Kaveri in 1902 was the first hydroelectric plant in Asia.[4] The Krishna Raja Sagara Dam has a capacity of 49 tmc ft.[11] 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.[12] Water stored in Krishna Raja Sagara amounted to only 4.6 tmc ft.[12] Water sharing{{further|Kaveri River water dispute}}As per Supreme Court order (16 feb 2018)[13] Karnataka will get 284.75 tmc ft, Tamil Nadu will get 404.25 tmc ft, Kerala will get 30 tmc ft and Puducherry will get 7 tmc ft, 10 tmc ft will be reserved for Environmental Protection and 4 tmc ft will be reserved for Inevitable Wastage into the Sea.[14] Cauvery Water Management Authority (CWMA) and Cauvery Water Regulation Committee (CWRC) 2018{{unsourced section|date=January 2019}}Acting on the Supreme Court's direction, the Centre constituted a Cauvery Water Management Authority (CMA) on 1st June 2018 to address the dispute over sharing of river water among Tamil Nadu, Karnataka, Kerala and Puducherry. On February 16 2018, the apex court had directed the government to form the CMA within six weeks in a verdict that marginally increased Karnataka's share of Cauvery water, reduced the allocation for Tamil Nadu and sought to settle the protracted water dispute between the two sout. On June 22 2018, Despite opposition from Karnataka, the Central government constituted the Kaveri Water Regulation Committee as per the provisions in the Kaveri Management Scheme laid down by the Supreme Court. Central Water Commission chairman, S. Masood Hussain will head the CWMA and chief engineer of the Central Water Commission, Navin Kumar will be the first chairman of the CWRC. While the CWMA is an umbrella body, the CWRC will monitor water management on a day-to-day basis, including the water level and inflow and outflow of reservoirs in all the basin states. See also
