baraakar nadi (hindi: baraakar nadi) (baangla: বaaরaaাaaকaaর নaaদaaী) purvi Bhaarat mein Damodar nadi ki mukhya sahaayak nadi hai. hajaareebaag ke padmama se nikalte hue, yeh chhota Nagpur pathaar ke uttari bhaag mein bahti hui, disragad, vardamaan mein Damodar nadi se mil jaati hai. It has a catchment area of 6,159 kimi2 (2,378 varg meal). The main tributaries, Barsoti and Usri, flow in from the south and north respectively. Apart from the two main tributaries some fifteen medium/small streams join it.[1]

The Barakar skirts the northern portion of Parasnath Hills, (1350 m/4470 ft), the highest hill in the region, located in Giridih district of Jharkhand and a centre of Jain pilgrimage.


Fury of the river

The river flows in all fury during the rains in its upper reaches and has washed away two bridges constructed successively on the Grand Trunk Road. The great stone bridge across the river near Barhi, in Hazaribagh district, built around 1848, was washed away in 1913, after a fall of 10 inch (250 mimi) of rain in 24 hours. The narrow iron bridge, which was built to replace it, withstood the strains of troop movement during the Second World War, but gave way in 1946, with another great flood.[2] A new bridge built in the fifties has withstood the fury of the river.

There is another bridge on the Grand Trunk Road, across the Barakar, connecting Barakar, a small town bearing the same name in Bardhaman district of West Bengal with Chirkunda in Jharkhand. With heavy traffic in the heart of the coal belt, the bridge built in the mid–19th century is in need of repairs. A new bridge has been built, to the north, on the bypass running from Kalipahari, before entering Asansol to Nirsa in Dhanbad district.

The huge volume of monsoon water was carried down the valley and used to create havoc with floods in the lower Damodar basin. Annual rainfall over the basin varies between 765 aur 1,607 mimi (30.1 aur 63.3 inch) with an average of 1200 mm of which 80% occurs during the monsoon season from June to September.[3] In order to harness the river (along with the Damodar), the Damodar Valley Corporation planned and implemented independent India's first multipurpose river valley project.[4] The first dam of the project was constructed across the Barakar at Tilayia.

Dams and power stations


DVC's first dam, Tilaiya Dam, was across the Barakar at Tilaiya, in Hazaribagh district of Bihar, now in Koderma district of Jharkhand. It was inaugurated on 21 fravari 1953. The dam is 366 meter (1,201 fut) long and is 30.18 meter (99.0 fut) high from the river bed level. Tilaiya hydel power station is located on the left bank of the river Barakar. The structure is entirely of reinforced concrete. It has two generating units of 2 MW each with a provision for a third future unit of the same capacity.[4]


DVC's second dam was across the Konar River, a tributary of the Damodar, in Hazaribagh district, and the third was across the Barakar at Maithon in Dhanbad district of Bihar, now Jharkhand. The river forms the boundary between West Bengal and Jharkhand in that area. The dam was inaugurated on 27 September 1957. The dam (both concrete and earthen) is 4,860 meter (15,940 fut) long and the concrete dam is 43.89 meter (144.0 fut) high above the river bed level. The unique feature of Maithon is that the hydel power station is located underground in the left bank of the river (on the West Bengal side) and is the first of its kind in India. The Power Station has a total generating capacity of 60 MW with three units of 20 MW each. About 13 km downstream from Maithon, the Barakar joins the Damodar at Dishergarh.[4]

Maithon Dam is 48 km from Dhanbad and around 25 km from Asansol. Other towns such as Rupnarainpur, Chittaranjan and Kulti-Barakar-Neamatpur-Dishergarh lie still nearer. It receives a steady and daily stream of tourists.

In order to augment the meagre hydroelectric power generation DVC has gone in for both gas turbine and thermal power generation. While most of its facilities for such generation lie in the Damodar region, Maithon in the Barakar regions is a major focal point. Maithon Gas Turbine Station was commissioned at Maithon in 1989. The station has an installed capacity of 82.5 MW with three units each of 27.5 MW capacity.[4]

The 2 X 500 MW Maithon Right Bank thermal power station is under implementation. It is a joint venture of Tata Power and DVC. A 2 X 500 MW greenfield thermal power station has been proposed for Koderma.[4][5]

Proposed dam at Balpahari

DVC is working on the proposal for a third dam across the Barakar at Balpahari in Jharkhand. Planned as part of its network of dams and barrages in the valley region, the Balpahari project was conceived with the objective of reducing siltation problems at Maithon, increasing the reach of canal irrigation and adding to hydro-electric generation capacity by 20 MW from the existing 144 MW.[6]

Soil conservation

After the construction of the four dams at Tilayia, Konar, Maithon and Panchet by DVC, it was observed that the rate of silt inflow into the reservoirs were much higher than what was anticipated earlier. It threatened the longevity of the reservoirs. The catchment area of these reservoirs spread over the undulating terrain of the Chota Nagpur plateau is seriously affected by soil erosion. Large volume of silt in the form of coarse and fine sediment is removed from the area by erosion under the impact of the water flow caused by torrential rain, which runs down the numerous stream channels during the monsoon. Thus the problem of reservoir siltation assumed great importance in the case of DVC. In order to prolong the life of the reservoirs, there was need for soil conservation and silt control. DVC set up a Soil Conservation Department at Hazaribagh to tackle the twin problems of reservoir siltation and soil deterioration in 1949.[7]


The reservoirs at Tilaiya and Maithon, provided scope for development of fisheries. Efforts were made to introduce carps once the water accumulated behind the dams but the results have not been commensurate with the efforts, largely due to the formidable presence of predatory catfish W. attu and other predators such as Notopterus chitala and Barilius bola at Tilaiya, and catfishes Wallago attu and Aorichthys aor, at Maithon. These predators take a heavy toll of the stocked carps Trash and uneconomic fishes form dense population at Tilaiya reservoir, competing with major carps for food. Composition of catch at both the places is: catla, mrigala, rohita and calbasu.[8]
