The Bhagirathi is considered to be the source in Hindu culture and mythology, although the Alaknanda is longer, and therefore, hydrologically the source stream. The headwaters of the Alakananda are formed by snow melt from peaks such as Nanda Devi, Trisul, and Kamet. The Bhagirathi rises at the foot of Gangotri Glacier, at Gomukh, at an elevation of and being mythologically referred to as residing in the matted locks of Shiva; symbolically Tapovan, which is a meadow of ethereal beauty at the feet of Mount Shivling, just away.

, and the size of its drainage basin. The name ''Ganges'' is used for the river between the confluence of the Bhagirathi and Alaknanda rivers, in the Himalayas, and the first bifurcation of the river, near the Farakka Barrage and the India-Bangladesh Border. The length of the Ganges is frequently said to be slightly over long, about , or . In these cases the river's source is usually assumed to be the source of the Bhagirathi River, Gangotri Glacier at Gomukh and its mouth being the mouth of the Meghna River on the Bay of Bengal. Sometimes the source of the Ganges is considered to be at Haridwar, where its Himalayan headwater streams debouch onto the Gangetic Plain. In some cases, the length of the Ganges is given by its Hooghly River distributary, which is longer than its main outlet via the Meghna River, resulting in a total length of about , if taken from the source of the Bhagirathi, or , if from Haridwar to the Hooghly's mouth. In other cases the length is said to be about , from the source of the Bhagirathi to the Bangladesh border, where its name changes to ''Padma''. For similar reasons, sources differ over the size of the river's drainage basin. The basin covers parts of four countries, India, Nepal,

The Himalayan portion of the basin includes the south-eastern portion of the state of Himachal Pradesh, the entire state of Uttarakhand, the entire country of Nepal and the extreme north-western portion of the state of West Bengal. The discharge of the Ganges also differs by source. Frequently, discharge is described for the mouth of the Meghna River, thus combining the Ganges with the Brahmaputra and Meghna. This results in a total average annual discharge of about , or . In other cases the average annual discharges of the Ganges, Brahmaputra, and Meghna are given separately, at about for the Ganges, about for the Brahmaputra, and about for the Meghna. The maximum peak discharge of the Ganges, as recorded at Hardinge Bridge in Bangladesh, exceeded . The minimum recorded at the same place was about , in 1997. The hydrologic cycle in the Ganges basin is governed by the Southwest Monsoon. About 84% of the total rainfall occurs in the monsoon from June to September. Consequently, streamflow in the Ganges is highly seasonal. The average dry season to monsoon discharge ratio is about 1:6, as measured at Hardinge Bridge. This strong seasonal variation underlies many problems of land and water resource development in the region. The seasonality of flow is so acute it can cause both drought and floods. Bangladesh, in particular, frequently experiences drought during the dry season and regularly suffers extreme floods during the monsoon. In the Ganges Delta, many large rivers come together, both merging and bifurcating in a complicated network of channels. The two largest rivers, the Ganges and Brahmaputra, both split into distributary channels, the largest of which merge with other large rivers before themselves joining the Bay of Bengal. But this current channel pattern was not always the case. Over time the rivers in Ganges Delta have often changed course, sometimes altering the network of channels in significant ways. Before the late 12th century the Bhagirathi-Hooghly distributary was the main channel of the Ganges and the Padma was only a minor spill-channel. The main flow of the river reached the sea not via the modern Hooghly River but rather by the Adi Ganga. Between the 12th and 16th centuries, the Bhagirathi-Hooghly and Padma channels were more or less equally significant. After the 16th century, the Padma grew to become the main channel of the Ganges. It is thought that the Bhagirathi-Hooghly became increasingly choked with silt, causing the main flow of the Ganges to shift to the southeast and the Padma River. By the end of the 18th century, the Padma had become the main distributary of the Ganges. One result of this shift to the Padma was that the Ganges now joined the Meghna and Brahmaputra rivers before emptying into the Bay of Bengal. The present confluence of the Ganges and Meghna was formed very recently, about 150 years ago. Also near the end of the 18th century, the course of the lower Brahmaputra changed dramatically, significantly altering its relationship with the Ganges. In 1787 there was a great flood on the Teesta River, which at the time was a tributary of the Ganges-Padma River. The flood of 1787 caused the Teesta to undergo a sudden change course, an avulsion, shifting east to join the Brahmaputra and causing the Brahmaputra to shift its course south, cutting a new channel. This new main channel of the Brahmaputra is called the Jamuna River. It flows south to join the Ganges-Padma. During ancient times, the main flow of the Brahmaputra was more easterly, passing by the city of Mymensingh and joining the Meghna River. Today this channel is a small distributary but retains the name Brahmaputra, sometimes Old Brahmaputra. The site of the old Brahmaputra-Meghna confluence, in the locality of

. 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 as the upper channel but both however suffered a considerable diminution, owing probably to the new communication opened below the Jalanggi on the upper channel.


History

The first European traveller to mention the Ganges was the Greek envoy Megasthenes (ca. 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

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 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 of water from the Ganges to the Bhagirathi-Hooghly distributary to restore navigability at the Port of Kolkata. It was assumed that during the worst dry season the Ganges flow would be around , thus leaving 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 then India and Bangladesh would each receive 50% of the water, with each receiving at least 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, . 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

Religious and cultural significance


Embodiment of sacredness

The Ganges is a sacred river to Hindus along every fragment of its length. All along its course, Hindus bathe in its waters, paying homage to their ancestors and their gods by cupping the water in their hands, lifting it, and letting it fall back into the river; they offer flowers and rose petals and float shallow clay dishes filled with oil and lit with wicks (diyas).

"The Ganga", he wrote in his will, "is the river of India, beloved of her people, round which are intertwined her racial memories, her hopes and fears, her songs of triumph, her victories and her defeats. She has been a symbol of India's age-long culture and civilization, ever-changing, ever-flowing, and yet ever the same Ganga."


''Avatarana'' - Descent of Ganges

In late May or early June every year, Hindus celebrate the ''karunasiri'' and the rise of the Ganges from earth to heaven. The day of the celebration, ''Ganga Dashahara'', the ''Dashami'' (tenth day) of the

month Jyestha, brings throngs of bathers to the banks of the river. A dip in the Ganges on this day is said to rid the bather of ten sins (dasha = Sanskrit "ten"; hara = to destroy) or ten lifetimes of sins. Those who cannot journey to the river, however, can achieve the same results by bathing in any nearby body of water, which, for the true believer, takes on all the attributes of the Ganges. The ''karunasiri'' is an old theme in Hinduism with a number of different versions of the story. In the Vedic version,

'', or the nectar of the gods which then plunges to the earth and waters it with sustenance. In the Vaishnava version of the myth, the heavenly waters were then a river called ''Vishnupadi'' ( Sanskrit: "from the foot of Vishnu"). As Lord Vishnu as the avatar Vamana completes his celebrated three strides —of earth, sky, and heaven— he stubs his toe on the vault of heaven, punches open a hole and releases the ''Vishnupadi'', which until now had been circling the cosmic egg. Flowing out of the vault, she plummets down to Indra's heaven, where she is received by Dhruva, once a steadfast worshipper of Vishnu, now fixed in the sky as the Pole star. Next, she streams across the sky forming the Milky Way and arrives on the moon. She then flows down earthwards to Brahma's realm, a divine lotus atop Mount Meru, whose petals form the earthly continents. There, the divine waters break up, with one stream, the Bhagirathi, flowing down one petal into Bharatvarsha (India) as the Ganges. It is Shiva, however, among the major deities of the Hindu pantheon, who appears in the most widely known version of the ''avatarana'' story.

The Ganges descends is tamed in Shiva's locks, and arrives in the Himalayas. She is then led by the waiting Bhagiratha down into the plains at Haridwar, across the plains first to the confluence with the Yamuna at Prayag and then to Varanasi, and eventually to Ganges Sagar (Ganges delta), where she meets the ocean, sinks to the netherworld, and saves the sons of Sagara. In honour of Bhagirath's pivotal role in the ''avatarana'', the source stream of the Ganges in the Himalayas is named Bhagirathi, (Sanskrit, "of Bhagiratha").


Redemption of the Dead

As the Ganges had descended from heaven to earth, she is also considered the vehicle of ''ascent'', from earth to heaven. As the ''Triloka-patha-gamini'', (Sanskrit: ''triloka''= "three worlds", ''patha'' = "road", ''gamini'' = "one who travels") of the Hindu tradition, she flows in

. Among all hymns devoted to the Ganges, there are none more popular than the ones expressing the worshipper's wish to breathe his last surrounded by her waters. The ''Gangashtakam'' expresses this longing fervently:

I ask that I may leave of this body on your banks,
Drinking your water, rolling in your waves,
Remembering your name, bestowing my gaze upon you.
No place along her banks is more longed for at the moment of death by Hindus than Varanasi, the Great Cremation Ground, or '' Mahashmshana''. Those who are lucky enough to die in Varanasi, are cremated on the banks of the Ganges, and are granted instant salvation. If the death has occurred elsewhere, salvation can be achieved by immersing the ashes in the Ganges. If the ashes have been immersed in another body of water, a relative can still gain salvation for the deceased by journeying to the Ganges, if possible during the lunar "fortnight of the ancestors" in the Hindu calendar month of

pradana'', a rite for the dead, in which balls of rice and sesame seed are offered to the Ganges while the names of the deceased relatives are recited. Every sesame seed in every ball thus offered, according to one story, assures a thousand years of heavenly salvation for each relative. Indeed, the Ganges is so important in the rituals after death that the ''Mahabharata'', in one of its popular ''ślokas'', says, "If only (one) bone of a (deceased) person should touch the water of the Ganges, that person shall dwell honoured in heaven." As if to illustrate this truism, the ''Kashi Khanda'' (Varanasi Chapter) of the Skanda Purana recounts the remarkable story of ''Vahika'', a profligate and unrepentant sinner, who is killed by a tiger in the forest. His soul arrives before Yama, the Lord of Death, to be judged for the afterworld. Having no compensating virtue, Vahika's soul is at once dispatched to

The Purifying Ganges

Hindus consider the waters of the Ganges to be both pure and purifying. Regardless of all scientific understanding of its waters, the Ganges is always ritually and symbolically pure in Hindu culture. Nothing reclaims order from disorder more than the waters of the Ganga. Moving water, as in a river, is considered purifying in Hindu culture because it is thought to both absorb impurities and take them away. The swiftly moving Ganga, especially in its upper reaches, where a bather has to grasp an anchored chain to not be carried away, is especially purifying. What the Ganges removes, however, is not necessarily physical dirt, but symbolic dirt; it wipes away the sins of the bather, not just of the present, but of a lifetime. A popular paean to the Ganga is the ''Ganga Lahiri'' composed by a 17th-century poet Jagannatha who, legend has it, was turned out of his Hindu Brahmin caste for carrying on an affair with a Muslim woman. Having attempted futilely to be rehabilitated within the Hindu fold, the poet finally appeals to Ganga, the hope of the hopeless, and the comforter of last resort. Along with his beloved, Jagannatha sits at the top of the flight of steps leading to the water at the famous ''Panchganga'' Ghat in Varanasi. As he recites each verse of the poem, the water of the Ganges rises one step until in the end it envelops the lovers and carries them away. "I come to you as a child to his mother", begins the ''Ganga Lahiri''.Quoted in
I come as an orphan to you, moist with love.
I come without refuge to you, giver of sacred rest.
I come a fallen man to you, uplifter of all.
I come undone by disease to you, the perfect physician.
I come, my heart dry with thirst, to you, ocean of sweet wine.
Do with me whatever you will.


Consort, Shakti, and Mother

Ganga is a consort to all three major male deities of Hinduism. As Brahma's partner she always travels with him in the form of water in his kamandalu (water-pot). She is also Vishnu's consort. Not only does she emanate from his foot as ''Vishnupadi'' in the ''avatarana'' story, but is also, with

and Lakshmi, one of his co-wives. In one popular story, envious of being outdone by each other, the co-wives begin to quarrel. While Lakshmi attempts to mediate the quarrel, Ganga and Sarasvati, heap misfortune on each other. They curse each other to become rivers, and to carry within them, by washing, the sins of their human worshippers. Soon their husband, Vishnu, arrives and decides to calm the situation by separating the goddesses. He orders Sarasvati to become the wife of Brahma, Ganga to become the wife of Shiva, and Lakshmi, as the blameless conciliator, to remain as his own wife. Ganga and Sarasvati, however, are so distraught at this dispensation, and wail so loudly, that Vishnu is forced to take back his words. Consequently, in their lives as rivers they are still thought to be with him. It is Shiva's relationship with Ganga, that is the best-known in Ganges mythology. Her descent, the ''avatarana'' is not a one-time event, but a continuously occurring one in which she is forever falling from heaven into his locks and being forever tamed. Shiva, is depicted in Hindu iconography as ''Gangadhara'', the "Bearer of the Ganga", with Ganga, shown as spout of water, rising from his hair. The Shiva-Ganga relationship is both perpetual and intimate. Shiva is sometimes called ''Uma-Ganga-Patiswara'' ("Husband and Lord of Uma (Parvati) and Ganga"), and Ganga often arouses the jealousy of Shiva's better-known consort. Ganga is the '' shakti'' or the moving, restless, rolling energy in the form of which the otherwise recluse and unapproachable Shiva appears on earth. As water, this moving energy can be felt, tasted, and absorbed. The war-god Skanda addresses the sage

in the ''Kashi Khand'' of the '' Skanda Purana'' in these words:
One should not be amazed ... that this Ganges is really Power, for is she not the Supreme Shakti of the Eternal Shiva, taken in the form of water?
This Ganges, filled with the sweet wine of compassion, was sent out for the salvation of the world by Shiva, the Lord of the Lords.
Good people should not think this Triple-Pathed River to be like the thousand other earthly rivers, filled with water.
The Ganga is also the mother, the ''Ganga Mata'' (''mata''="mother") of Hindu worship and culture, accepting all and forgiving all. Unlike other goddesses, she has no destructive or fearsome aspect, destructive though she might be as a river in nature. She is also a mother to other gods. She accepts Shiva's incandescent seed from the fire-god Agni, which is too hot for this world and cools it in her waters. This union produces Skanda, or Kartikeya, the god of war. In the '' Mahabharata'', she is the wife of Shantanu, and the mother of heroic warrior-patriarch,
Bhishma Bhishma (Sanskrit: भीष्‍म, , ), also known as Pitamaha, Gangaputra, and Devavrata, played an integral role in Mahabharata. He was the supreme commander of the Kaurava forces during the Kurukshetra War mentioned in the Hindu epic M ...
. When Bhishma is mortally wounded in battle, Ganga comes out of the water in human form and weeps uncontrollably over his body. The Ganges is the distilled lifeblood of the Hindu tradition, of its divinities, holy books, and enlightenment. As such, her worship does not require the usual rites of invocation (''avahana'') at the beginning and dismissal (''visarjana'') at the end, required in the worship of other gods. Her divinity is immediate and everlasting.


Ganges in classical Indian iconography

Early in ancient Indian culture, the river Ganges was associated with fecundity, its redeeming waters, and its rich silt providing sustenance to all who lived along its banks. A counterpoise to the dazzling heat of the Indian summer, the Ganges came to be imbued with magical qualities and to be revered in anthropomorphic form. By the 5th century CE, an elaborate mythology surrounded the Ganges, now a goddess in her own right, and a symbol for all rivers of India. Hindu temples all over India had statues and reliefs of the goddess carved at their entrances, symbolically washing the sins of arriving worshippers and guarding the gods within. As protector of the sanctum sanctorum, the goddess soon came to be depicted with several characteristic accessories: the '' makara'' (a crocodile-like undersea monster, often shown with an elephant-like trunk), the '' kumbha'' (an overfull vase), various overhead parasol-like coverings, and a gradually increasing retinue of humans. Central to the goddess's visual identification is the ''makara'', which is also her '' vahana'', or mount. An ancient symbol in India, it pre-dates all appearances of the goddess Ganga in art. The ''makara'' has a dual symbolism. On the one hand, it represents the life-affirming waters and plants of its environment; on the other, it represents fear, both fear of the unknown which it elicits by lurking in those waters, and real fear which it instils by appearing in sight. The earliest extant unambiguous pairing of the ''makara'' with Ganga is at the Udayagiri Caves in Central India (circa 400 CE). Here, in the Cave V, flanking the main figure of Vishnu shown in his boar incarnation, two river goddesses, Ganga and Yamuna appear atop their respective mounts, ''makara'' and ''

, Central India, in the left-most frame above. The ''gana'' represents both posterity and development (''udbhava''). The pairing of the fearsome, life-destroying ''makara'' with the youthful, life-affirming ''gana'' speaks to two aspects of the Ganges herself. Although she has provided sustenance to millions, she has also brought hardship, injury, and death by causing major floods along her banks. The goddess Ganga is also accompanied by a dwarf attendant, who carries a cosmetic bag, and on whom she sometimes leans, as if for support. (See, for example, frames 1, 2, and 4 above.) The ''purna kumbha'' or full pot of water is the second most discernible element of the Ganga iconography. Appearing first also in the relief in the Udayagiri Caves (5th century), it gradually appeared more frequently as the theme of the goddess matured. By the 7th century it had become an established feature, as seen, for example, in the

Worshipped even today, the full pot is emblematic of the formless Brahman, as well as of woman, of the womb, and of birth. Furthermore, The river goddesses Ganga and Saraswati were both born from Brahma's pot, containing the celestial waters. In her earliest depictions at temple entrances, the goddess Ganga appeared standing beneath the overhanging branch of a tree, as seen as well in the Udayagiri caves. However, soon the tree cover had evolved into a '' chatra'' or parasol held by an attendant, for example, in the 7th-century Dasavatara temple at Deogarh. (The parasol can be clearly seen in frame 3 above; its stem can be seen in frame 4, but the rest has broken off.) The cover undergoes another transformation in the temple at Kharod, Bilaspur (9th or 10th century), where the parasol is lotus-shaped, and yet another at the Trimurti temple at Badoli where the parasol has been replaced entirely by a lotus. As the iconography evolved, sculptors, especially in central India, were producing animated scenes of the goddess, replete with an entourage and suggestive of a queen en route to a river to bathe. A relief similar to the depiction in frame 4 above, is described in as follows:
A typical relief of about the ninth century that once stood at the entrance of a temple, the river goddess Ganga is shown as a voluptuously endowed lady with a retinue. Following the iconographic prescription, she stands gracefully on her composite ''makara'' mount and holds a water pot. The dwarf attendant carries her cosmetic bag, and a ... female holds the stem of a giant lotus leaf that serves as her mistress's parasol. The fourth figure is a male guardian. Often in such reliefs, the ''makara'' tail is extended with great flourish into a scrolling design symbolizing both vegetation and water.

Other activities include religious discussions, devotional singing, mass feeding of holy men and women and the poor, and religious assemblies where doctrines are debated and standardized. Kumbh Mela is the most sacred of all the pilgrimages. Thousands of holy men and women attend, and the auspiciousness of the festival is in part attributable to this. The sadhus are seen clad in saffron sheets with ashes and powder dabbed on their skin per the requirements of ancient traditions. Some called '' naga sanyasis'', may not wear any clothes.

built an irrigation canal on the Yamuna River in the early 17th century. It fell into disuse until 1830, when it was reopened as the Eastern Yamuna Canal, under British control. The reopened canal became a model for the Upper Ganges Canal and all following canal projects. The first British canal in India (which did not have Indian antecedents) was the Ganges Canal built between 1842 and 1854. Contemplated first by Col. John Russell Colvin in 1836, it did not at first elicit much enthusiasm from its eventual architect Sir Proby Thomas Cautley, who balked at the idea of cutting a canal through extensive low-lying land to reach the drier upland destination. However, after the Agra famine of 1837–38, during which the East India Company's administration spent Rs. 2,300,000 on famine relief, the idea of a canal became more attractive to the company's budget-conscious Court of Directors. In 1839, the

The Court of Directors, moreover, considerably enlarged the scope of the projected canal, which, in consequence of the severity and geographical extent of the famine, they now deemed to be the entire Doab region. The enthusiasm, however, proved to be short-lived. Auckland's successor as Governor-General, Lord Ellenborough, appeared less receptive to large-scale public works, and for the duration of his tenure, withheld major funds for the project. Only in 1844, when a new Governor-General, Lord Hardinge, was appointed, did official enthusiasm and funds return to the Ganges canal project. Although the intervening impasse had seemingly affected Cautley's health and required him to return to Britain in 1845 for recuperation, his European sojourn gave him an opportunity to study contemporary hydraulic works in the United Kingdom and Italy.

A long canal, with another of branch lines, eventually stretched between the headworks in Haridwar, splitting into two branches below Aligarh, and its two confluences with the Yamuna (Jumna in map) mainstem in Etawah and the Ganges in Kanpur (Cawnpore in map). The Ganges Canal, which required a total capital outlay of £2.15 million, was officially opened in 1854 by Lord Dalhousie. According to historian Ian Stone:

Dams and barrages

A major barrage at Farakka was opened on 21 April 1975, It is located close to the point where the main flow of the river enters Bangladesh, and the tributary Hooghly (also known as Bhagirathi) continues in West Bengal past Kolkata. This barrage, which feeds the Hooghly branch of the river by a long feeder canal, and its water flow management has been a long-lingering source of dispute with Bangladesh.

Economy

The Ganges Basin with its fertile soil is instrumental to the agricultural economies of India and Bangladesh. The Ganges and its tributaries provide a perennial source of irrigation to a large area. Chief crops cultivated in the area include rice,

s and lakes provides a rich growing area for crops such as legumes, chillies, mustard, sesame, sugarcane, and jute. There are also many fishing opportunities along the river, though it remains highly polluted. Also, the major industrial towns of Unnao and Kanpur, situated on the banks of the river with the predominance of tanning industries add to the pollution.


Tourism

Tourism is another related activity. Three towns holy to Hinduism—Haridwar, Allahabad (Prayagraj), and Varanasi—attract millions of pilgrims to its waters to take a dip in the Ganges, which is believed to cleanse oneself of sins and help attain salvation. The rapids of the Ganges are also popular for river rafting in the town of Rishikesh, attracting adventure seekers in the summer months. Several cities such as Kanpur, Kolkata and Patna have also developed riverfront walkways along the banks to attract tourists.


Ecology and environment

Human development, mostly agriculture, has replaced nearly all of the original natural vegetation of the Ganges basin. More than 95% of the upper Gangetic Plain has been degraded or converted to agriculture or urban areas. Only one large block of relatively intact habitat remains, running along the Himalayan foothills and including Rajaji National Park, Jim Corbett National Park, and Dudhwa National Park. As recently as the 16th and 17th centuries the upper Gangetic Plain harboured impressive populations of wild Asian elephants (''Elephas maximus''), Bengal tigers (''Panthera t. tigris''), Indian rhinoceros (''Rhinoceros unicornis''), gaurs (''Bos gaurus''), barasinghas (''Rucervus duvaucelii''),

There are no endemic birds in the upper Gangetic Plain. The great Indian bustard (''Ardeotis nigriceps'') and lesser florican (''Sypheotides indicus'') are considered globally threatened. The natural forest of the upper Gangetic Plain has been so thoroughly eliminated it is difficult to assign a natural vegetation type with certainty. There are a few small patches of forest left, and they suggest that much of the upper plains may have supported a tropical moist deciduous forest with sal ('' Shorea robusta'') as a climax species. A similar situation is found in the lower Gangetic Plain, which includes the lower Brahmaputra River. The lower plains contain more open forests, which tend to be dominated by '' Bombax ceiba'' in association with ''

''. There are early seral forest communities that would eventually become dominated by the climax species sal (''Shorea robusta'') if forest succession was allowed to proceed. In most places forests fail to reach climax conditions due to human causes. The forests of the lower Gangetic Plain, despite thousands of years of human settlement, remained largely intact until the early 20th century. Today only about 3% of the ecoregion is under natural forest and only one large block, south of Varanasi, remains. There are over forty protected areas in the ecoregion, but over half of these are less than . The fauna of the lower Gangetic Plain is similar to the upper plains, with the addition of a number of other species such as the smooth-coated otter (''Lutrogale perspicillata'') and the large Indian civet (''Viverra zibetha'').


Fish

It has been estimated that about 350 fish species live in the entire Ganges drainage, including several

. This dolphin used to exist in large schools near urban centres in both the Ganges and Brahmaputra rivers but is now seriously threatened by pollution and dam construction. Their numbers have now dwindled to a quarter of their numbers of fifteen years before, and they have become extinct in the Ganges' main tributaries. A recent survey by the World Wildlife Fund found only 3,000 left in the water catchment of both river systems. The Ganges river dolphin is one of only five true freshwater dolphins in the world. The other four are the

Effects of climate change

The Tibetan Plateau contains the world's third-largest store of ice. Qin Dahe, the former head of the China Meteorological Administration, said that the recent fast pace of melting and warmer temperatures will be good for agriculture and tourism in the short term; but issued a strong warning: In 2007, the
Intergovernmental Panel on Climate Change The Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental body of the United Nations. Its job is to advance scientific knowledge about climate change caused by human activities. The World Meteorological Organization (WMO) a ...
(IPCC), in its Fourth Report, stated that the Himalayan glaciers which feed the river were at risk of melting by 2035. The IPCC has now withdrawn that prediction, as the original source admitted that it was speculative and the cited source was not a peer-reviewed finding. In its statement, the IPCC stands by its general findings relating to the Himalayan glaciers being at risk from global warming (with consequent risks to water flow into the Gangetic basin). Many studies have suggested that climate change will affect the water resources in the Ganges river basin including increased summer (monsoon) flow, and peak runoff could result in an increased risk of flooding.


Pollution and environmental concerns

The Ganges suffers from extreme pollution levels, caused by the 400 million people who live close to the river. Sewage from many cities along the river's course, industrial waste and religious offerings wrapped in non-degradable plastics add large amounts of pollutants to the river as it flows through densely populated areas. The problem is exacerbated by the fact that many poorer people rely on the river on a daily basis for bathing, washing, and cooking. The World Bank estimates that the health costs of

equal three percent of India's GDP. It has also been suggested that eighty percent of all illnesses in India and one-third of deaths can be attributed to water-borne diseases. Varanasi, a city of one million people that many pilgrims visit to take a "holy dip" in the Ganges, releases around 200 million liters of untreated human sewage into the river each day, leading to large concentrations of
fecal coliform A fecal coliform (British: faecal coliform) is a facultatively anaerobic, rod-shaped, gram-negative, non-sporulating bacterium. Coliform bacteria generally originate in the intestines of warm-blooded animals. Fecal coliforms are capable of growth ...
bacteria. According to official standards, water safe for bathing should not contain more than 500 fecal coliforms per 100 ml, yet upstream of Varanasi's ghats the river water already contains 120 times as much, 60,000 fecal coliform bacteria per 100 ml."India and pollution: Up to their necks in it"

Even today, holy men, pregnant women, people with leprosy or chicken pox, people who have been bitten by snakes, people who have committed suicide, the poor, and children under 5 are not cremated at the ghats but are left to float free, to decompose in the waters. In addition, those who cannot afford the large amount of wood needed to incinerate the entire body, leave behind a lot of half-burned body parts. After passing through Varanasi, and receiving 32 streams of raw sewage from the city, the concentration of fecal coliforms in the river's waters rises from 60,000 to 1.5 million, with observed peak values of 100 million per 100 ml. Drinking and bathing in its waters therefore carries a high risk of infection. Between 1985 and 2000, Rs. 10 billion, around US$226 million, or less than 4 cents per person per year, were spent on the

, an environmental initiative that was "the largest single attempt to clean up a polluted river anywhere in the world". The Ganga Action Plan has been described variously as a "failure", a "major failure". According to one study,
The Ganga Action Plan, which was taken on priority and with much enthusiasm, was delayed for two years. The expenditure was almost doubled. But the result was not very appreciable. Much expenditure was done on political propaganda. The concerning governments and the related agencies were not very prompt to make it a success. The public of the areas was not taken into consideration. The release of urban and industrial wastes in the river was not controlled fully. The flowing of dirty water through drains and sewers were not adequately diverted. The continuing customs of burning dead bodies, throwing carcasses, washing of dirty clothes by washermen, and immersion of idols and cattle wallowing were not checked. Very little provision of public latrines was made and the open defecation of lakhs of people continued along the riverside. All these made the Action Plan a failure.
The failure of the Ganga Action Plan has also been variously attributed to "environmental planning without proper understanding of the human-environment interactions", Indian "traditions and beliefs", "corruption and a lack of technical knowledge" and "lack of support from religious authorities". In December 2009 the World Bank agreed to loan India US$1 billion over the next five years to help save the river. According to 2010 Planning Commission estimates, an investment of almost Rs. 70 billion (Rs. 70 billion, approximately US$1.5 billion) is needed to clean up the river. In November 2008, the Ganges, alone among India's rivers, was declared a "National River", facilitating the formation of a National Ganga River Basin Authority that would have greater powers to plan, implement and monitor measures aimed at protecting the river. In July 2014, the Government of India announced an integrated Ganges-development project titled ''Namami Gange Programme'' and allocated 2,037
crore A crore (; abbreviated cr) denotes ten million (10,000,000 or 107 in scientific notation) and is equal to 100 lakh in the Indian numbering system. It is written as 1,00,00,000 with the local 2,2,3 style of digit group separators (one lakh is e ...
for this purpose. The main objectives of the Namami Gange project is to improve the water quality by the abatement of pollution and rejuvenation of river Ganga by creating infrastructures like sewage treatment plants, river surface cleaning, biodiversity conservation, afforestation, and public awareness.

declared the Ganges River a legal "person", in a move that according to one newspaper, "could help in efforts to clean the pollution-choked rivers". , the ruling has been commented on in Indian newspapers to be hard to enforce, that experts do not anticipate immediate benefits, that the ruling is "hardly game changing", that experts believe "any follow-up action is unlikely", and that the "judgment is deficient to the extent it acted without hearing others (in states outside Uttarakhand) who have stakes in the matter." The incidence of water-borne and enteric diseases—such as gastrointestinal disease, cholera, dysentery, hepatitis A and typhoid—among people who use the river's waters for bathing, washing dishes and brushing teeth is high, at an estimated 66% per year. Recent studies by Indian Council of Medical Research (ICMR) say that the river is so full of killer pollutants that those living along its banks in Uttar Pradesh, Bihar, and Bengal are more prone to cancer than anywhere else in the country. Conducted by the National Cancer Registry Programme under the ICMR, the study throws up shocking findings indicating that the river is thick with heavy metals and lethal chemicals that cause cancer. According to Deputy Director-General of NCRP A. Nandkumar, the incidence of cancer was highest in the country in areas drained by the Ganges and stated that the problem would be studied deeply and with the findings presented in a report to the health ministry. Apart from that, many NGOs have come forward to rejuvenate the river Ganges. Vikrant Tongad, an Environmental specialist from SAFE Green filed a petition against Simbhaoli Sugar Mill (Hapur UP) to NGT. NGT slapped a fine of Rs. 5 crores to Sugar Mill also, a fine of 25 Lakhs to Gopaljee Dairy for discharging untreated effluents into the Simbhaoli drain.


Water shortages

Along with ever-increasing pollution, water shortages are getting noticeably worse. Some sections of the river are already completely dry. Around Varanasi, the river once had an average depth of , but in some places, it is now only .


Mining

Illegal mining in the Ganges river bed for stones and sand for construction work has long been a problem in Haridwar district, Uttarakhand, where it touches the plains for the first time. This is despite the fact that quarrying has been banned in
