Anjum Sultan Shahbaz recorded some stories of the name Jhelum in his book Tareekh-e-Jhelum as: However, some writers believe that when "Dara-e-Azam" reached a certain place on the river bank after winning many battles, he fixed his flag at that place and called it "Ja-e-Alam" which means "Place of the Flag". With the passage of time it became Jhelum from "Ja-e-Alam".'' The Sanskrit name of this river is Vitasta. The river's name is derived from an apocyryphal legend regarding the origin of the river as explained in Nilamata Purana. Goddess Parvati was requested by sage Kasyapa to come to Kashmir for purification of the land from evil practices and impurities of Pisachas living there. Goddess Parvati then assumed the form of a river in the Nether World. Then Lord Shiva made a stroke with his spear near the abode of Nila. By that stroke of the spear, Goddess Parvati came out of the Nether World. Shiva himself named her as Vitasta. He had excavated with the spear a ditch measuring one Vitasti, through which the river – gone to the Nether World – had come out, so she was given the name Vitasta by him.
History
The river Jhelum is called Vitastā in the Rigveda and Hydaspes by the ancient Greeks. The Vitastā is mentioned as one of the major rivers by the holy scriptures — the Rigveda. It has been speculated that the Vitastā must have been one of the seven rivers mentioned so many times in the Rigveda. The name survives in the Kashmiri name for this river as Vyeth. According to the major religious work Srimad Bhagavatam, the Vitastā is one of the many transcendental rivers flowing through land of Bharata, or ancient India. Alexander the Great and his army crossed the Jhelum in BC 326 at the Battle of the Hydaspes River where he defeated the Indian king, Porus. According to Arrian, he built a city "on the spot whence he started to cross the river Hydaspes", which he named Bukephala to honour his famous horse Bukephalus or Bucephalus which was buried in Jalalpur Sharif. It is thought that ancient Bukephala was near the site of modern Jhelum City. According to a historian of Gujrat district, Mansoor Behzad Butt, Bukephalus was buried in Jalalpur Sharif, but the people of Mandi Bahauddin, a district close to Jehlum, believed that their tehsilPhalia was named after Alexander's dead horse, saying that the name Phalia was a distortion of Bucephala. The waters of the Jhelum are allocated to Pakistan under the terms of the Indus Waters Treaty. India is working on a hydropower project on a tributary of Jhelum river to establish first-use rights on the river water over Pakistan as per the Indus Waters Treaty.
Mythology
The river was regarded as a god by the ancient Greeks, as were most mountains and streams; the poet Nonnus in the Dionysiaca makes the Hydaspes a titan-descended god, the son of the sea-god Thaumas and the cloud-goddess Elektra. He was the brother of Iris, the goddess of the rainbow, and half-brother to the Harpies, the snatching winds. Since the river is in a country foreign to the ancient Greeks, it is not clear whether they named the river after the god, or whether the god Hydaspes was named after the river.
The river has rich power generation potential in India. Water control structures are being built as a result of the Indus Basin Project, including the following:
Mangla Dam, completed in 1967, is one of the largest earthfill dams in the world, with a storage capacity of
Trimmu Barrage, constructed in 1939 some 20 km from Jhang Sadar at the confluence with the Chenab, has maximum discharge capacity of 645,000 ft³/s.
Haranpur Constructed in 1933 Approximate 5 km from Malakwal near Chak Nizam Village. Its length is 1 km mainly used by Pakistan Railways but there is a passage for light vehicles, motorcycles, cycles and pedestrians at one side.
The Rasul-Qadirabad Link Canal runs from the Rasul Barrage to the Chenab.
The Chashma-Jhelum Link Canal runs from the Chashma Barrage on the Indus River to the Jhelum river downstream of Rasul Barrage. This is from Mari Shah Sakhira town.
