The Ganges runs 2,500 miles with a basin of 9,243 miles shared between India, Bangladesh, Nepal and China
The Barrage diverts water into the Baghirathi-Hooghly River to flush out silt and increase navigation accessibility to Calcutta.
No further agreements were reached from 1988-1996 India withdrew 40-45,000 ft/s from the Gangues every dry season of this period In 1996 the two countries reached a 30 year treaty This treaty dictates that Bangladesh receive a minimum flow of 35,000 ft/s from January to May The relationship created by the 1996 treaty resulted in further agreements between India and Bangladesh
Increased erosion rates and sedimentation Increased salt water intrusion More sever flooding during the monsoon seasonDirect damages are estimated to be three billion US dollars

The Ganges/ Brahmaputra system has the third largest discharge and largest sediment load in the world, 1,086,000 ft/s and 1.84 billion tons a year respectively1
Bangladesh experiences widespread flooding during the monsoon season Droughts are common in the dry season when the Ganges flow into Bangladesh is only 55,000 ft/sWater is desperately needed in the dry season for crop irrigation
The source of the Gangues lies in the Himalayas It is fed mainly by glacial melt from April to June Flow is severely seasonal Heaviest flows occur during monsoon months, June to October, which bring 85% of all rainfall to the area
In 2003 the basin was home to 405 million people, 346 in India, 19 in Nepal, 40 in Bangladesh

India and Bangladesh were unable to reach a water agreement 1975 In 1976 Bangladesh failed to involve the United Nations In 1977 a five year water sharing treaty was reached This treaty gave Bangladesh 80% of Ganges flow during the dry season This was followed by two memorandums of understanding lasting through 1988, these did not include a minimum flow into Bangladesh.
The Barrage was commissioned in April 1975 This Barrage gave India control over Ganges flows into Bangladesh during the dry season In the spring of 1975 India withdrew 40,000 of the 55,000 ft/s of water from the GangesThere were disastrous consequences on Bangladesh
In 1951 India announced intentions build a Barrage across the Gangues 10km from the Bangladesh border Google Maps,

Little silt was flushed from the Baghirathi-Hooghly River Calcutta has declined as a port city
Increased salinity of soil and water Decline of soil quality and crop yields Shrinking fish population Decline of fishing villages and loss of a livelihoods Decline of mangrove forest
