From UPSC perspective, the following things are important :
Prelims level : Godavari– Cauvery Link Project
Mains level : Interlinking of rivers
The draft Detailed Project Report (DPR) of the Godavari and Cauvery River Linking Project has been completed by National Water Development Agency (NWDA).
Godavari– Cauvery Link Project
- The project consists of 3 links viz., Godavari (Inchampalli/Janampet) – Krishna (Nagarjunasagar), Krishna (Nagarjunasagar) – Pennar (Somasila) and Pennar (Somasila) – Cauvery (Grand Anicut).
- This proposal to link Godavari, which is prone to flooding, and Krishna, which doesn’t have enough water, has been around for several decades.
- While river-interlinking for the purposes of navigation as an idea was mooted by the British in India, in 1972, engineer and Union Minister KL Rao proposed the linking of Godavari and Krishna for irrigation.
- The decades-old proposal finally took shape in the 2000s, and in 2016, the Andhra government linked the two rivers with the Pattiseema-Polavaram Lift Irrigation project, in Andhra’s West Godavari district.
