<P> From this reservoir, water is pumped up to the elevation of nearly 425 m MSL (near to 21 ° 55 ′ 17" N 86 ° 09 ′ 07" E ﻿ / ﻿ 21.92139 ° N 86.15194 ° E ﻿ / 21.92139; 86.15194) in the Brahmani river basin for further transfer in most of the area of Damodar River basin, Subarnarekha River basin, Brahmani River basin, Mahanadi River basin in Jharkhand, Odisha, Chhattisgarh and West Bengal states . The Hasdeo Bango reservoir (near 22 ° 36 ′ 47" N 82 ° 37 ′ 27" E ﻿ / ﻿ 22.61306 ° N 82.62417 ° E ﻿ / 22.61306; 82.62417) would receive the Ganga water and further pumped into the Narmada, Sone, Tapti, Yamuna, Sutlej, Luni, Chambal, Ghaggar, Ganga, etc. river basins for using in Maharashtra, Madhya Pradesh, Chhattisgarh, south Uttar Pradesh, south Bihar, Rajasthan, Gujarat, Haryana, Punjab and Delhi states . See Google earth maps for more geographical information . Further, water can be pumped into the Bagh reservoir and Upper Indravati reservoir located in Godavari River basin to transfer Ganga water into Godavari basin and further to south Indian river basins . </P> <P> The minimum water flow from Bangladesh coast to the Bay of Bengal sea is 7,000 cumecs which is equal to 220 bcm annually . This water can also be put to use in addition to the impounded water by the water reservoir . The advantage of this scheme is that Ganga and Bramhaputra river waters can be stored on Bay of Bengal sea area and nearly 440 bcm water @ 14,000 cumecs transferred throughout the year to other river basins including Ganga basin at optimum pumping head . </P> <P> Nearly 1000 million tons (500 million cubic meters) of sediment annually from Ganga and Brahmaputra rivers is settling in the sea coast of Bangladesh and India and the sea area is shallow (up to 15 m depth) for at least 50 km wide . Bangladesh plagued with high population density, can reclaim nearly 6,000 km (4% of its total land) area of sea by excavating / dredging sediment from the fresh water lagoon bed without any effect on the water storage of the off - shore fresh water reservoir . </P> <P> The presence of the protective sea dike makes sub sea soil dredging easier and economical through protection from rough sea waves . This reclaimed area from the sea can be utilised for locating a megacity to cater to the modern needs of Bangladesh . This off shore dike would protect the Bangladesh from the wave and tidal activity during the frequent cyclones preventing human and property losses drastically and also from sea level rise due to global warming . Thus Bangladesh would also benefit immensely with this off shore fresh water reservoir project . </P>
