Overview

Upper Bhadra Project is a major lift irrigation scheme under implementation in the central region of Karnataka State. It envisages lifting of water in first stage from Tunga to Bhadra and lifting of water in second stage from Bhadra reservoir and providing it to Tunnel near Ajjampura through gravity canal in Tungabhadra sub-basin of Krishna basin from there to irrigate an extent of 2,25,515 hectares by micro irrigation in drought-prone districts of Chikmagalur, Chitradurga, Tumkur and Davanagere and to fill up 367 tanks coming under the drought prone taluks of the three district through Chitradurga branch Canal and Tumkur branch canal. The primary objective of the projects is providing susbtainable irrigation facility in Khariff season and the other objective of the project is to recharge the ground water table, dilute the chemical contaminants of which Fluoride is predominant.

Aim of the Project and Description of Works

The comprehensive project envisages providing irrigation and drinking water to the  parched lands of Central Karnataka plateau and specifically as below,

  • Providing irrigation facility for an area of 2,25,515 Ha of land in Tarikere, Kadur taluks of Chikkamagalur district, Hosadurga, Hiriyur, Chitradurga and Challakere taluks of Chitradurga district, Jagalur taluk of Davanagere district and Sira, Chikkanayakanahalli taluks of Tumkur district.  The total requirement of water for irrigation in the command area is 539.07 MCM (19.04 TMC).
  • Filling up of 367 Nos of Tanks to their 50% of live capacity are proposed. The requirement of water for the purpose is 307.48 MCM (10.86 TMC) including augmentation of 2.00 TMC of Vani Vilas Sagar Reservoir. The filling up of tanks will facilitate recharging of ground water besides diluting the fluoride content.
