In this component, NWDA studied in depth water balance studies of various major river basins including Mahanadi, Godavari, Krishna, Pennar, Cauvery, Vaigai, West flowing rivers of Kerala, Karnataka, north of Bombay and south of Tapi and southern tributaries of Yamuna to establish water surplus and deficit regions. These studies indicate that while Mahanadi and Godavari basins are water surplus, other basins in Peninsular India such as Krishna, Pennar, Cauvery and Vaigai are water deficit. As a next step, pre-feasibility studies for 16 probable links were carried out. Feasibility Studies of all the links under Peninsular Component have been completed except for two links namely Netravati - Hemavati and Bedti - Varda links for which consent of Government of Karnataka.
1. Bedti-Varda link: Survey & Investigation work could not be carried out due to opposition by local people /NGO. As per latest information Govt. of Karnataka stated that efforts are continued to convince NGO/Local people.
2. Netravati-Hemavati:- Govt. of Karnataka categorically stated that since river Netravati is an intra-state river, its waters are vested with the State of Karnataka vide reference to Entry 17 of the State list of the 7th Schedule to the Constitution and hence it is entirely the prerogative of Karnataka to decide on the manner of utilization of the Netravati water. The Govt. of Karnataka is planning to utilize Netravati river waters to meet the drinking requirements for Bangalore city and other drought prone districts. After meeting these requirements, the surplus if any, available in Netravati will be informed to National Water Development Agency.
