Massanjore Dam is a hydropower generating dam over the Mayurakshi River located at Massanjore near Dumka in the state of Jharkhand, India. The Massanjore dam (also called Canada Dam), across the Mayurakshi, was commissioned in 1955. It was formally inaugurated by Lester B. Pearson, Foreign Minister of Canada.
Massanjore dam is about 38 kilometres (24 mi) upstream from Siuri in West Bengal. It is 47 metres (155 ft) high from its base and is 660 metres (2,170 ft) long. The reservoir has an area of 67.4 square kilometres (16,650 acres) when full and has a storage capacity of 620,000,000 cubic metres (500,000 acre·ft). It cost Rs. 16.10 crore.
Mayurakshi Left Bank Canal- Length 20.54 kilometres (Lined Canal).
Mayurakshi Right Bank Canal-Yet to be constructed.
The dam was funded by the counterpart rupee fund created through supplies of wheat and other materials from Canada for use in India. Canada devoted those rupees to the further development of the Mayurakshi dam project.
Unfortunately, the Massanjore dam was not allowed to have a flood reserve. In 1956 the state government selectively took over flood control embankments till then maintained by the landlords or local bodies.
