Farakka Barrage, Malda, West Bengal India

ompleted in 1974-75 , the Farakkah Barrage is a dam on the Ganges River located in the Indian state of West Bengal. The dam was built to divert the Ganges River water into the Hooghly River during the dry season, from January to June, in order to flush out the accumulating silt which in the 1950s and 1960s was a problem at the major port of Kolkata on the Hooghly River. Bangladesh and India have had many debates about how the Farakka Barrage cuts off Bangladesh"s water supply. This is the longest barrage in the world and has recently been entered into the Guinness Book of World Records. The barrage was constructed by the Hindustan Construction Company Limited.
