Recently, linking of which of the following rivers was undertaken?
- (a) Cauvery and Tungabhadra
- (b) Godavari and Krishna ✓ UPSC's answer
- (c) Mahanadi and Sone
- (d) Narmada and Tapti
Why the answer is (b)
• In September 2015 Andhra Pradesh completed the Pattiseema lift scheme, diverting Godavari water through the Polavaram right canal into the Krishna river above the Prakasam barrage — India's first major river-linking project — option (b).
• It helps the Krishna delta and frees Krishna water for Rayalaseema.
• Cauvery–Tungabhadra (a), Mahanadi–Sone (c) and Narmada–Tapti (d) links remain proposals.
• Hence option (b).
Why the other options are wrong
- (a) Cauvery and Tungabhadra
- Cauvery–Tungabhadra linking has not been undertaken.
- (c) Mahanadi and Sone
- Mahanadi–Sone is a proposal only.
- (d) Narmada and Tapti
- Narmada–Tapti linking has not been undertaken.
