Hooghly River
The Hugli River is the westernmost distributary of the Ganges, situated in West Bengal, India. It is known in its upper reaches as the Bhagirathi. The Bhagirathi splits off from the main branch of the Ganges at Giria. A short distance west, it meets the man-made Farakka Feeder Canal, which massively increases its flow. The river then flows south to join the Jalangi at Nabadwip, where it becomes the Hooghly proper. The Hooghly continues southwards, passing through the metropolis of Kolkata. Thereafter, it empties into the Bay of Bengal. Its tributaries include the Ajay, Damodar, Rupnarayan, and Haldi.
The Hooghly has religious significance as Hindus consider the river sacred. It also plays a major role in the agriculture, industry, and climate of the state.
Course
The vast majority of the water that flows into the Hooghly River is provided by the man-made Farakka Feeder Canal, rather than the natural source of the river at Giria. The Farakka Barrage is a dam that diverts water from the Ganges into the Farakka Feeder Canal near the town of Tildanga in Murshidabad district, located 40 km upstream from Giria. This supplies the Hooghly with water as per the agreement between India and Bangladesh. The feeder canal runs parallel to the Ganges, past Dhulian, until just above Jahangirpur where the canal ends and joins the Bhagirathi river. The Bhagirathi then flows south past Jiaganj Azimganj, Murshidabad and Baharampur.South of Baharampur and north of Palashi it used to form the border between Bardhaman District and Nadia District, but while the border has remained the same the river is now often east or west of its former bed. The river then flows south past Katwa, Nabadwip, Kalna and Jirat. At Kalna it originally formed the border between Nadia District and Hooghly District, and then further south between Hooghly District and North 24 Parganas District. It flows past Halisahar, Chinsurah, Naihati, Bhatpara, Konnagar, Serampore, and Kamarhati. Then, just before entering the twin cities of Kolkata and Howrah, it turns to the southwest. At Nurpur it enters an old channel of the Ganges, and turns south to empty into the Bay of Bengal through an estuary about wide .Ain-i-Akbari, a book by Abu'l-Fazl, describes that the river Ganga and river Sarwasati streams of lower Bengal had different flows. According to the footnotes of this book, the colour of the water of the Sarawasati was white, the colour of another stream named Jamuna was blue, and the colour of the Ganga was muddy and yellowish. From Kolkata the main flow of the Hooghly-Bhagirathi used to run along the side of the Kalighat temple, Baruipur, Jaynagar Majilpur, Chhatrabhog and Hatiagarh. At that time, between Khiderpore and Sankrail no flow existed. Presently, the stream between Khiderpore and Sankrail became known as KatiGanga. A channel had been dug at the time of Alibardi Khan in the middle of the 18th century. This happened with the assistance of Dutch traders, who also set up a toll point on the Hooghly river. So the present reach of the Hooghly is the lower part of the historical Saraswati. Kolkata the capital of West Bengal is located on the banks of the Hoogly river.
Tidal bore
The tide runs rapidly on the Hooghly, and produces a remarkable example of the fluvial phenomenon known as a tidal bore. This consists of the head-wave of the advancing tide, hemmed in where the estuary narrows suddenly into the river, and often exceeds in height. It is felt as high up as Naihati 35 km upstream of Calcutta, and frequently destroys small boats. A tidal bore which overcame the banks of the river in 1876 was reported to have killed up to a hundred thousand people. The difference from the lowest point of low-water in the dry season to the highest point of high-water in the rains is reported to be. The greatest mean rise of tide, about, takes place in March, April or May - with a declining range during the rainy season to a mean of, and a minimum during freshets of.History
In its upper reaches the river is generally known as the Bhāgirathi, until it reaches Hooghly. The word Bhāgirathi literally means "caused by Bhagiratha", a Hindu mythological Solar dynasty prince who was instrumental in bringing the river Ganges from heaven to the earth, in order to release his 60,000 grand-uncles from a curse of the saint Kapila.In 1974, the Farakka Barrage began diverting water into the Hooghly during the dry season so as to reduce the silting difficulties at Kolkata's port.
Like the rest of the Ganges, the Bhāgirathi-Hooghly is considered sacred to Hindus, and its water is considered holy.

- East West Metro Tunnel - The tunnel was completed in 2021. This tunnel is the first underwater river railway tunnel in India. It is a metro railway tunnel, connecting Kolkata to Howrah.
Economics
The river provides a perennial supply of water to the plain of West Bengal for irrigation and human & industry consumption. The river is navigable and a major transport system in the region with a large traffic flow. For a long time, the Calcutta Port was the biggest port of India. Although in the past its significance had gone down, recently it has reached the 3rd position in the list of Indian Ports. The modern container port of Haldia, on the intersection of lower Hooghly and Haldi River, now carries much of the region's maritime trade. One new port will be built in the deep sea to reduce the load on Calcutta port.
Despite the river being polluted, the fish from it are important to the local economy.
The Hooghly river valley was the most important industrial area of the state of Bengal. Despite a decline of the jute industry, the prime industry of this region, it is still one of the biggest industrial areas of India. It has a number of small cities which form the Greater Kolkata agglomeration, the second biggest Indian city and the former capital.
In September 2015, the Government of West Bengal announced that renovation of the Hooghly riverfront in Kolkata will be completed with the help of World Bank funding under the National Ganga River Basin Project Scheme.
