Upper Bhadra Project: A Milestone in Karnataka's Water Security

A successful trial run delivered water from the Bhadra reservoir through the Chitradurga Branch Canal to Gonur Lake, ending a 50-year wait for residents of central Karnataka. This marks the operational initiation of the Upper Bhadra Project, addressing severe water scarcity in the region's semi-arid zones.

Key Features of the Upper Bhadra Project

  • National Project Status: It is the first irrigation scheme in Karnataka to be accorded 'National Project' status by the central government, qualifying it for substantial central financial assistance.
  • Project Cost: A Rs 21,500-crore lift irrigation scheme.
  • Water Source: Draws water from the Tunga and Bhadra rivers to mitigate acute water distress.

Operational Mechanism: Two-Stage Lift Irrigation System

  • Stage 1: Lifting water from the Tunga River and transferring it to the Bhadra Reservoir.
  • Stage 2: Lifting water from the Bhadra Reservoir and routing it through a 6.9 km tunnel to feed the Chitradurga and Tumakuru branch canals.

Core Objectives

  • Irrigate over 2.25 lakh hectares of drought-prone land.
  • Fill 367 minor irrigation tanks across Chitradurga, Davanagere, Tumakuru, and Chikkamagaluru districts.

Bhadra River: Geographic Context

  • Origin: Western Ghats (Gangamoola peak).
  • Course: Flows east across the Deccan Plateau.
  • Confluence: Meets the Tunga River at Koodli (near Shivamogga) to form the Tungabhadra River.
  • Drainage: The Tungabhadra is a major tributary of the Krishna River, which eventually empties into the Bay of Bengal.

Significance for India

  • Water Security: Addresses chronic water scarcity in the semi-arid districts of central Karnataka.
  • Agriculture: Boosts irrigation coverage in drought-prone regions, supporting agrarian livelihoods.
  • Federal Cooperation: Exemplifies central-state partnership in funding large infrastructure through National Project status.
  • Model for Lift Irrigation: Demonstrates the role of lift irrigation and tunnel-based conveyance in overcoming topographical challenges of the Deccan Plateau.
