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 the present status are as given:
- Bedti-Varda Link :
The Government of Karnataka has conveyed its approval for preparation of DPR of Bedti-Varada Link by NWDA. Accordingly, the preparation of DPR of this link proposal has been included in the work programme of NWDA for the year 2019-20.
- Netravati-Hemavati :
The Government of Karnataka indicated that Government has planned Yettinhole project as such they are not in favour of taking up feasibility report of Netravati-Hemavati link.
