Damodar Valley Project is a joint venture of Jharkhand and West Bengal. The project sets an example towards managing our water resources on scientific lines. Before completion of this project, flood in Damodar River caused damage to thousands of people and loss of property worth crores of rupees every year.
So it was called the 'Sorrow of Bihar (now Jharkhand) and West Bengal'. After the completion of this project the river has become a 'boon to' these states. Damodar valley has the largest deposits of black gold i.e., coal. Iron ore deposits of India are also found in its vicinity. The project consists of a series of small dams on the tributaries of Damodar. There are a few hydel- power stations.
2. The Bhakra-Nangal Project:
Bhakra-Nangal Project is a joint venture of Punjab, Himachal Pradesh and Haryana. Under this project, two dams have been constructed over the river Satluj. They are the Bhakra Dam and the Nangal Dam. The Bhakra-Nangal Project is an example of water management on scientific lines on the largest scale.
The Bhakra Dam has been built at a strategic point where two hills on either side of the Satluj are very close to each other. The dam therefore, is not very wide. It is the highest dam in the world. Its height is 26 metres from the river-bed. It is located in the seismic zone, and the hills that act as huge natural walls for storing 7,80,000 hectare-metres of water are made up of unconsolidated matter.
The other dam is 12 km down stream at Nangal. Under this project 1100 km long canals and 3100 kms long distributaries irrigate 14 lakh hectares of agricultural land. The project generates 1204 MW of electricity annually.
3. Hirakund Project:
It consists of three dams including the Hirakund Dam, the largest dam in the world across Mahanadi in Orissa. The canals have the capacity to irrigate 10 lakh hectares of land.
There are two power houses that have helped the steel plants, fertilizer plants and other
