Damodar River valley:
Context:
West Bengal Chief Minister Mamata Banerjee blamed the Damodar Valley Corporation (DVC) for the devastating floods in North Bengal, calling them “man-made.” She alleged that the DVC released water from reservoirs without coordination, worsening the situation in Darjeeling and nearby areas already battered by record rainfall.
Geographical Significance:
Damodar river originates from Khamarpat Hills in the Chotanagpur Plateau, in Palamau district, Jharkhand.
The basin can be divided into upper (Jharkhand), middle, and lower (West Bengal) segments. The upper and middle regions are hilly and rugged, whereas the lower segment forms a flat alluvial plain with fertile soil.
The Lower Damodar River conjoins with Hooghly River at Falta, approximately 50 km downstream of Kolkata.
Historically, it was notorious for its devastating floods, earning it the name "Sorrow of Bengal".
Drainage and Dams in the Valley:
Its important triburtaries are Barakar, Konar, Bokaro, Ghari and Bhera. The Barakar is the largest tributary of Damodar.
Dams at Tilaiya, Maithon, Konar, and Panchet (run by DVC since 1948) deal with flood control, irrigation for nearly a million acres, hydropower, and even regional navigation.
Industrial Significance:
The Damodar Valley forms the core of India’s mineral and industrial belt, often termed the “Ruhr of India” due to its resource-driven industrialization.
The valley contains India’s largest coking coal reserves, especially in Jharia, Raniganj, Bokaro, and Karanpura coalfields.
The Gondwana formations provide abundant iron ore, mica, bauxite, and limestone, supporting heavy industries.
Damodar Valley Corporation (DVC):
DVC is a statutory body established by an Act of Parliament in 1948.
DVC was modelled after the Tennessee Valley Authority (TVA) in the United States.
Its major objectives are:
Flood control
Irrigation
Power generation (both thermal and hydel).
The DVC currently has an installed power capacity of 7,107 MW.
