The basin area of the Ganges river in Bangladesh is extremely dependent on a regular water supply from upstream to meet requirements for agriculture, fisheries, navigation, salinity control, domestic and industrial sectors. In 1975 India commissioned a barrage on the Ganga river at Farakka to divert significant portion of the dry season flow in order to make the Calcutta port navigable. Statistical analysis of discharge and water level data have been carried out to determine if significant changes have occurred in the hydrology of the Ganges system in Bangladesh in the post-Farakka period.
