Godavari River originates in the Western Ghats, flows through Maharashtra, and drains into the Bay of Bengal.

- Aim - To irrigate lands and provide drinking water.
- Governed by - The Godavari Water Disputes Tribunal (GWDT) Award.
- Technical clearances issued by - The Central Water Commission.
- Legal Provision - India’s framework for resolving interstate river disputes is based on the Inter-State River Water Disputes Act, 1956.
- Under this law, when states fail to resolve water sharing disagreements, the Union government can constitute a tribunal, whose award is final and binding, with the force of a SC decree.
- It was under this law that the Krishna Water Disputes Tribunal (KWDT) and the Godavari Water Disputes Tribunal (GWDT) were constituted in 1969.
- Initial Permission - Polavaram was initially permitted to divert 80 thousand million cubic feet (TMC) of water from the Godavari to the Krishna River.
- Telangana’s opposition - It faces strong opposition from Telangana, which argues it violates water-sharing laws from the AP Reorganisation Act.
- Andhra Pradesh has maintained that the diversion involves only “flood” or “surplus” waters of the Godavari.
