TUNGABHADRA RIVER DISPUTE

NEWS: The Union Government has proposed a High-Level Committee after Karnataka, Andhra Pradesh, and Telangana reached a rare consensus to resolve the long-pending Tungabhadra basin water-sharing dispute.

About

  • Major right-bank tributary of the Krishna River.
  • Formed by the confluence of the Tunga and Bhadra rivers at Kudli (Karnataka).
  • Originates in the Western Ghats (Varaha Parvatha–Gangamoola).
  • Flows about 531 km through Karnataka, Andhra Pradesh, and Telangana before joining the Krishna River at Sangameswaram.

Tungabhadra Reservoir Project

  • Commissioned in the 1950s near Hosapete, Karnataka.
  • Irrigates about 16.38 lakh acres across Karnataka, Andhra Pradesh, and Telangana.

Water Sharing

  • Governed by the Krishna Water Disputes Tribunal-I (1969) under Justice R.S. Bachawat.
  • Water allocated in a 65:35 ratio between Karnataka and the undivided Andhra Pradesh.
  • After the 2014 bifurcation, Telangana was allocated 15.9 TMC from the Tungabhadra system.

Key Issues

  • Heavy siltation has reduced the reservoir's original 134 TMC storage capacity.
  • Poor condition of the Rajolibanda Diversion Scheme (RDS) limits Telangana's utilisation to 5–6 TMC.
  • Upper Bhadra Project: Andhra Pradesh has challenged Karnataka's lift irrigation project in the Supreme Court, citing reduced downstream flows.

Constitutional & Legal Framework

  • Entry 17, State List: Water is a State subject.
  • Entry 56, Union List: Regulation and development of inter-State rivers.
  • Article 262: Parliament can provide for adjudication of inter-State river disputes and exclude Supreme Court jurisdiction through the Inter-State River Water Disputes Act, 1956.
