The present study briefly describes available streamflow generated within Bangladesh, inflows from the Brahmaputra-Ganges-Padma Meghna River (main river system), cross-boundary inflows from India, static water resources, instream storage potential, streamflow salinity, and water demands in different sectors like domestic and industrial uses, navigation, salinity control, fisheries, agricultural water use, etc. It reveals that Bangla desh has a two-fold water problem-too much in the monsoon season, causing devastating floods and too little in the dry season, causing severe drought. As a result, saline water intrusion occurs in the dry season from the Bay of Bengal and streamflow salinity increases up to 10, 000μmho/cm, especially in the Southwest (Passur River) and South Central (Baleswar River) Regions. In Bangladesh water demand for different purposes is increasing day by day. Due to the scarcity of water supply in the dry season, normal life for the people and development activities in the country are hindered. For the sake of the survival of humans and animals and a safe environment, necessary water supply should be ensured in both the monsoon and dry seasons through properly planned Barrage Projects.
