History of River Ganga

The Ganges also known as Ganga, is a trans-boundary river of Asia which flows through the nations of India and Bangladesh. The 2,525 km (1,569 mi) river rises in the western Himalayas in the Indian state of Uttarakhand, and flows south and east through the Gangetic  Plain of North India. After entering West Bengal, it divides into two rivers: The Hooghly River, or Adi Ganga, flows through several districts of West Bengal and into the Bay of Bengal near Sagar Island. The other, the Padma River, flows into and through Bangladesh, and also empties into the Bay of Bengal. The Ganges is the third largest river in the world by discharge.

 River Ganga

The Ganges is one of the most sacred rivers to Hindus.It is also a lifeline to millions of Indians who live along its course and depend on it for their daily needs. It is worshipped in Hinduism as the goddess Ganga.It has also been important historically, with many former provincial or imperial capitals (such as Kannauj, Kampilya,  Kara, Prayag or Allahabad, Kashi, Pataliputra or Patna, Hajipur, Munger, Bhagalpur, Murshidabad, Baharampur, Nabadwip, Saptagram, Kolkata and Dhaka) located on its banks.

The Ganges is highly polluted. Pollution threatens not only humans, but also more than 140 fish species, 90 amphibian species and the endangered Ganges river dolphin. The levels of fecal coliform bacteria from human waste in the waters of the river near Varanasi are more than 100 times the Indian government's official limit. The Ganga Action Plan, an environmental initiative to clean up the river, has been a major failure thus far, due to corruption, lack of technical expertise,poor environmental planning,and lack of support from religious authorities

History...

The Late Harappan period, about 1900–1300 BCE, saw the spread of Harappan settlement eastward from the Indus River basin to the Ganges-Yamuna doab, although none crossed the Ganges to settle its eastern bank. The disintegration of the Harappan civilisation, in the early 2nd millennium BC, marks the point when the centre of Indian civilisation shifted from the Indus basin to the Ganges basin. There may be links between the Late Harappan settlement of the Ganges basin and the archaeological culture known as "Cemetery H", the Indo-Aryan people, and the Vedic period.

This river is the longest in India. During the early Vedic Age of the Rigveda, the Indus and the Sarasvati River were the major sacred rivers, not the Ganges. But the later three Vedas gave much more importance to the Ganges. The Gangetic Plain became the centre of successive powerful states, from the Maurya Empire to the Mughal Empire. The first European traveller to mention the Ganges was Megasthenes ( 350–290 BCE). He did so several times in his work Indica: "India, again, possesses many rivers both large and navigable, which, having their sources in the mountains which stretch along the northern frontier, traverse the level country, and not a few of these, after uniting with each other, fall into the river called the Ganges. Now this river, which at its source is 30 stadia broad, flows from north to south, and empties its waters into the ocean forming the eastern boundary of the Gangaridai, a nation which possesses a vast force of the largest-sized elephants." (Diodorus II.37). In the rainy season of 1809, the lower channel of the Bhagirathi, leading to Kolkata, had been entirely shut; but in the following year it opened again, and was nearly of the same size with the upper channel; both however suffered a considerable diminution, owing probably to the new communication opened below the Jalanggi on the upper channel.

In 1951 a water sharing dispute arose between India and East Pakistan (now Bangladesh), after India declared its intention to build the Farakka Barrage. The original purpose of the barrage, which was completed in 1975, was to divert up to 1,100 m3/s (39,000 cu ft/s) of water from the Ganges to the Bhagirathi-Hooghly distributary in order to restore navigability at the Port of Kolkata. It was assumed that during the worst dry season the Ganges flow would be around 1,400 to 1,600 m3/s (49,000 to 57,000 cu ft/s), thus leaving 280 to 420 m3/s (9,900 to 14,800 cu ft/s) for the then East Pakistan. East Pakistan objected and a protracted dispute ensued. In 1996 a 30-year treaty was signed with Bangladesh. The terms of the agreement are complicated, but in essence they state that if the Ganges flow at Farakka was less than 2,000 m3/s (71,000 cu ft/s) then India and Bangladesh would each receive 50% of the water, with each receiving at least 1,000 m3/s (35,000 cu ft/s) for alternating ten-day periods. However, within a year the flow at Farakka fell to levels far below the historic average, making it impossible to implement the guaranteed sharing of water. In March 1997, flow of the Ganges in Bangladesh dropped to its lowest ever, 180 m3/s (6,400 cu ft/s). Dry season flows returned to normal levels in the years following, but efforts were made to address the problem. One plan is for another barrage to be built in Bangladesh at Pangsha, west of Dhaka. This barrage would help Bangladesh better utilise its share of the waters of the Ganges.
