Bhadra Dam
Encyclopedia
The Bhadra Dam, which has created the Bhadra Reservoir (ಭಧ್ರಾ ಜಲಾಶಯ), is located on the Bhadra River
a tributary of Tungabhadra River
in Chikkamagaluru district in Tarikere
Taluk, in the western part of Karnataka
in South India
. The benefits derived from the reservoir storage are irrigation with gross irrigation potential of 162818 hectares (402,331.7 acre), hydro power generation of 39.2 MW (three powerhouses, located on the right and left bank main canals), drinking water supply and industrial use. The dam commissioned in 1965 is a composite earth cum masonry structure of 59.13 metres (194 ft) height with length of 1708 metres (5,603.7 ft) at the crest level, which submerges a land area of 11250.88 hectares (27,801.5 acre).

Aroli hill range of Kudremukh
range, and flows east across the Deccan Plateau. It is joined by its tributaries, the Somavahini (drains from a crater and meets Bhadra River at Hebbe), Thadabehalla, and Odirayanahalla. The river flows through the city of Bhadravathi and the Bhadra Wildlife Sanctuary
. The Bhadra meets the Tunga River
at Koodli
, a small town near Shivamogga. The combined river continues east as the Tungabhadra
, a major tributary of the Krishna
, which empties into the Bay of Bengal
. The Bhadra Dam is built across the Bhadra River, 1.5 kilometre (0.93205910497471 mi) from Lakkavalli
village and 50 kilometres (31.1 mi) upstream of the confluence of the Bhadra River and Tungabhadra River. Shimoga city is located 28 kilometres (17.4 mi) north of the dam. The Bhadra Dam drains a catchment area of 1968 square kilometre out of which the forest area is 717.49 hectares (1,773 acre), cultivable land is 3274.65 hectares (8,091.8 acre) and fallow land is 7258.74 hectares (17,936.7 acre). The catchment and command areas of the project lie in Chikamagalur, Shimoga and Davanagere
districts. A number of industries, urban and rural settlements dependent on assured water supply lie on the banks of the river and in the project command area; Kudremukh Iron Ore Company Ltd, the Mysore Paper Mills and Vishweshvarayya Iron and Steel Industries are the major industrial activity noted in the command area of the project. Fishing activities have also increased on the bank of the river; 81 fish species from 8 orders with 14 families are recorded as endemic to the Bhadra River.
The Bhadra River basin receives an average annual rainfall of 2320 mm with rainfall occurring during monsoon period (June to November). The rainfall is experienced both during the Southwest Monsoon
and North East monsoon
; inflow contribution is 82 % from SW monsoon (June to September) and 18% from north-eastern monsoon (October to December). The annual yield assessed from a catchment area of 1968 square kilometre at the dam site is 84.63 BCF (billion cubic feet) in a 75% dependable year. Based on recordings taken over a period of 25 years, it has an estimated annual mean evapotranspiration
of 1,678 mm.
. The dam was built to a height of 59.13 metres (194 ft) (above the river bed level) between 1947 (start of construction) and 1965 (year of commissioning). It has a gross storage capacity of 2.025 km3, live storage of 63.00 BCF at full reservoir level and a dead storage of 8.50 BCF at RL (reservoir level) of 631.54 metres (2,072 ft). The storage created by the reservoir is according to the allocation of 61.70 BCF (1.747 km3 including direct evaporation of 0.14 km3) of water made under the Krishna Water Disputes Tribunal
Award. The dam is built on a shattered rock based with a central masonry spillway. It has an earthen embankment on the left side and a rock hillock on the opposite side. The Ogee type spillway in the middle section of the river has been provided with four numbers of vertical lift gates over a width of 18.28 metres (60 ft) and designed for a discharge of 3020 cubic metre/s. In addition, two number river sluices are also provided to pass a discharge of 13300 cubic metre/s. The annual siltation load considered in the design is 10.78 million cubic feet per square kilometer of catchment area. The canal outlets provided in the dam, initially for Hydropower generation followed by irrigation, consists of the left Bank canal outlet to discharge 10.76 cubic metre/s and two right bank canal outlets to pass a discharge of 75.03 cubic metre/s. There are several islands in the reservoir area which have been developed for tourism.
Submergence
The reservoir created by the dam submerged 27 villages. The reservoir submergence extends to water stretch of 13 kilometres (8.1 mi)/s upstream of the dam.
During the flood season, flooding of the Bhadravathi town have been experienced when large flows were released from the dam.
Irrigation benefits
The Left Bank Canal is designed to carry a discharge of 10.76 cubic metre/s, starting from the tail race of the left bank powerhouse provides irrigation facilities over its total length of 77 kilometres (47.8 mi). The Right Bank canal, originating from the tail race channel of the right bank powerhouse provides irrigation facilities through its length of the main canal of 103 kilometres (64 mi) designed to carry a discharge of 75.03 cubic metre/s and its branch canal system of 284.9 kilometres (177 mi). Gross command area from the project is 162818 hectares (402,331.7 acre), cultivable command is 121500 hectares (300,232.8 acre) and irrigated command and cropped area is 105570 hectares (260,868.9 acre). The soils encountered in the Right Bank Canal irrigation command consisted of Black Cotton Soils
8.5% and Red soil
93.5%, while on the Left Bank Canal command it comprises Black Cotton Soils 7.0% and Red soil 93%.
The irrigation component of the project was planned to provide an annual cropping intensity of 200 percent to irrigate semi-dry crops in nearly 60 percent of the command area dominated by red loamy soils. Irrigated area spreads over Chitradurga
, Shivamogga, Chikmagalur and Bellary
districts comprising predominantly red loamy soils except in some portions of the right bank canal area which consist of Black Cotton soils. However, the actual cropping was predominately rice and also sugarcane and permanent gardens; 90% area on the left bank canal system and 60% area of the right bank canal system was dominated by rice. This practice resulted in heavy demand on water causing serious concerns on the irrigation system itself. Consequently, National Water Management Project (NWMP) was launched with the objective to "rehabilitate and provide more equitable, predictable and reliable irrigation service which could improve agricultural productivity and farm income". This project has resulted in substantial improvements in both the area brought under irrigation and consequent agricultural crop production.
Power benefits
The water stored in the reservoir is diverted through the right and left bank power houses into the respective irrigation canal systems. The right bank powerhouse utilises the irrigation releases for power generation from two units of Kaplan-type turbine generators and one unit of 6MW capacity. The left bank powerhouse at the river bed utilizes the irrigation releases to generate power from two units of 12 MW capacity each and another power house on the left bank canal of one unit of 2 MW capacity. The three power stations together have a power generation capacity of 39.2 MW.
The Bhadra River flows through the Bhadra Tiger Reserve and Wildlife Sanctuary and the Bhadra Reservoir is on its northern border. The sanctuary has rich avifauna such as Junglefowl
, red spurfowl
, Painted Bush-quail, emerald dove
, southern Green Imperial Pigeon
, great black woodpecker
, Malabar Parakeet and hill myna
. Reptiles reported in the river and the reservoir are the Marsh crocodiles and monitor lizards. Common otter
and the Smooth Indian Otter
, Gaur
s, leopards are also commonly sighted fauna in the reserve. The wildlife can be viewed by taking a boat ride in the reservoir when Tyavarekoppa Lion and Tiger Safari and the Sakkrebyle Elephant camp can also be visited.
Marsh crocodiles are found all along the Bhadra River and more so after the river enters the sanctuary area and further flows through midst of the undisturbed moist deciduous forests till it joins the back waters of the reservoir of the Bhadra Dam.
Vegetation
The back water of the reservoir extends into the forest reserve which has "moist deciduous forest of the Tectona
-Dillenia
-Lagerstroemia series with patches of dry deciduous forest of the Anogeissus
–Tectona
-Terminalia
type forests occurring in the northern fringes". A key ecological feature of the forest is the presence of five species of bamboos, three are profusely found in the reserve forests.
Ecology
A study on ecological impact on native fish, fish habitat and riverine fisheries carried out by the Department of Studies in Environmental Science, University of Mysore
in the downstream reaches of the Bhadra River indicate adverse changes in the hydrological regime and water quality which have affected fish catches (and livelihood of people dependent on fisheries), particularly, large fishes are affected. Thus, from ecological considerations maintaining a minimum river flow by releasing minimum water from the reservoir to the downstream of the river became essential.
Recreation
The reservoir is also a popular venue for water sports activities like sailing
, kayaking
, water-cycling, water-trampoline and sport fishing.
