Upper Bhadra Project is a major lift irrigation Scheme under implementation in the central
region of Karnataka State. It envisages lifting upto17.40TMC of water in first stage
from Tunga to Bhadra and lifting 29.90TMCof water in second stage from Bhadra to Tunnel
near Ajjampura, in Tungabhadra sub-basin of Krishna basin. It is planned to irrigate an extent of
2,25,515 hectares by micro irrigation in drought-prone districts of Chikmagalur, Chitradurga,
Tumkur and Davangere.
The primary objective of the project is providing sustainable irrigation facility in Kharif
season and the other objective of the project is to recharge the ground water table and provide
drinking water by filling 367 tanks in drought-prone taluks of the above said districts.
The overall climate of the Chikkamagalur project site area is very agreeable and cool, as it
comprises of a large extent of hilly terrain. The cold season is from December to February,
followed by the hot season from March to May. The period from June to September
constitutes the Southwest monsoon season. October and November may be termed the post
monsoon or retreating monsoon season. The humidity is very high during the monsoon
season, generally exceeding 90 percent. It is comparatively less during the rest of the year. The
driest part of the year is the period of January to March.
The overall climate of the Chitradurga project site area including Command Area is very hot
and semidry, as it comprises of some extent of rocky hilly terrain. The cold season is from
December to February, followed by the hot season from March to May. The period
from June to September constitutes the Southwest monsoon season. October and
November may be termed the post monsoon or retreating monsoon season. The humidity is very
high during the monsoon season, generally exceeding 80 percent. It is comparatively less during
the rest of the year. The driest part of the year is the period of March to May.
The Tumkur district falls in the eastern dry agro climatic zone. The temperatures start rising
from January to peak in may, around 400 C is common. There after it declines during
the monsoon period. The humidity is lowest during the dry season and highest during
the monsoon period.
The Davangere district falls under central dry agro-climatic zone of the Karnataka state and is
categorized as drought prone. Normal climatic parameters of the district are increasing
temperature from March to May, usually maximum April month and minimum temperature that
is coldest month during month of December.
The Average Annual Rainfall in Chikkamagalur areas is 758 mm. It varies from a low of 595
mm in Kadur Taluk to a high of 2379 mm in Mudigere. Average Annual Rainfall in
Chikkamagalur District is 1904mm.
The Average Annual Rainfall in Chitradurga areas is475 mm and Average Annual Rainfall in
Chitradurga District is 486.7 mm. The maximum precipitation of over 80% of total annual
rainfall occurs in four months between April and October.
The probability of occurrence of Annual Rainfall of Tumkur areas between 500-800mm
is 75%. September is the wettest month with monthly rainfall in excess of 170 mm.
Annual Rainfalls in the district varies from over 900mm in Tumkur to around 600mm in
Pavagada.
The comprehensive project envisages providing irrigation and drinking water to the parched
1
lands of Central Karnataka plateau and in specific:
(i) 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
Chikkamagalur district, Hosadurga, Hiriyur, Chitradurga and Challakere taluks of
Chitradurga district, Jagalur taluk of Davangere 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).
(ii) 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 for Vani Vilas Sagar Reservoir. The filling up of tanks will
facilitate recharging of ground water besides diluting the fluoride content.
 The site is located at 13018’0’’ N Latitude and 750 28’0’’ E Longitude. The entire project site
includes the area from the offtake of Tunga River in Chikkamagalur District to
Command Area under Chitradurga District, Tumkur District & Davangere District. The
proposed Canal alignment, intake structure, various lift points, delivery chambers, tunnel
and command areas will pass through State and Reserved Forests. This project falls under K-8
Sub-basin.
 The project involve submergence and about 364.50 forest land is required for the project. The
Bhadra Wildlife Sanctuary is nearby to the project canal towards south direction hence the
project attracts general condition as mentioned in the Environmental Impact Notification -2006
and its subsequent amendments and falls under ‘A category’.
 The proposed irrigation is only in Kharif period and the intensity of irrigation is 100%.
 Villages benefited by the proposed project:
• Total villages benefited under Chikkamagalur District = 199 No.s
• Total villages benefited under Chitradurga District = 442 No.s
• Total villages benefited under Tumkur District = 110 No.s
• Total villages benefited under Davangere District = 36 No.s
• Total villages benefited = 199+442+110+36 = 787 No.s

2.00 TMC for Vani Vilas Sagar Reservoir. The filling up of tanks will facilitate recharging of
ground water besides diluting the fluoride content.
 The project involves submergence and about 364.50 forest land is required for the project. The
Bhadra Wildlife Sanctuary is nearby to the project canal towards south direction hence the
project attracts general condition as mentioned in the Environmental Impact Notification -2006
and its subsequent amendments and falls under ‘A category’.
2.3. Need for the project and its importance to the country and or region.
Major economic activity of the region is due to agricultural activities, which are heavily monsoon
dependent. However, due to the inconsistent monsoons and erratic rainfall, the overall agricultural
production and consequently the per capita income and the overall economy of the region is low. In
addition, the area situated in central part of the State, like many other areas is highly drought prone.
Irrigation projects have to a large extent mitigated the problems due to monsoons and droughts in many
areas in the region. This proposed project similarly will provide irrigation facilities to the 2,25,515 Ha of
land in Tarikere, Kadur taluks of Chikkamagalur district, Hosadurga, Hiriyur, Chitradurga and
Challakere taluks of Chikkamagalur district, Hosadurga, Hiriyur, Chitradurga and Challakere taluks
of Chitradurga district, Jagalur taluk of Davangere district and Sira, Chikkanayakanahalli taluks of
Tumkur district in addition to providing drinking water and sub-soil replenishment. Thus improving the
agricultural output and increasing the per-capita income of the people of the region while also improving
groundwater scenario and clean drinking water to the people of the villages in the taluks.
2.4. Demand-Supply
.The total requirement of water for irrigation in the command area is 539.07 MCM (19.04 TMC).
