Koel-Karo project

The Koel-Karo project is located in the Ranchi and West Singbhum districts. The 710 mw power project involves the construction of two earth dams - one, 44 metres high, across the South Koel river near Basia, and the other, 55 metres high, across the North Karo river near Lohajima. The two dams will be linked by a trans-basIn channel, with six units of 115 mw each in the underground powerhouse at Lumpu-ngkhel and one unit of 20 mw at Raitoli. About 120 villages are to be affected, displacing over one lakh people. 22,000 ha are to be submerged. Of the total land acquisition, 12,000 ha are reported to be agricultural land, while 10,000 ha comprise forests. Dispute arose over the compensation package for the displaced people and protests started in 1974 and have been continuing since then.
