Trimmu Barrage Chenab River

Information

On the River Chenab in Pakistan's Jhang District, which is part of the Punjab province, there is a dam called the Trimmu Barrage. It is situated further downstream from the point where the rivers Chenab and Jhelum converge. It is not far from Atharan Hazari, which is located close to the confluence of the Jhelum and Chenab rivers, and about 25 kilometers from the city of Jhang. As part of Pakistan's Indus Water Plan, it was one of the seven connection canals that had to be built. Following the Indus Water Treaty, Pakistan developed this plan.


Trimmu Barrage Chenab River



The Trimmu Barrage is used to regulate the flow of water into the River Chenab for agricultural purposes as well as to prevent flooding.


The Trimmu Barrage was constructed by English engineers between the years 1937 and 1939. For the business, James Douglas Hardy Bedford held the position of Chief Engineer. It eventually received a new name. primarily as a way to stop storms and protect the city of Jhang from their impacts. For increased security, the arched gridiron's bridge component has many safety bands built into it. This barrage has been improved in a variety of ways, including the building of new gates and the maintenance of the current gates. LTV is occasionally allowed, but until the barrage is dismantled on June 30, 2020, there is virtually no chance to drive an HTV. Both HTV and LTV transmitters are currently functional. In Head, repairs are now being made, and brand-new river crossings have been built.


Between Pakistan and India is a sizable body of water called the Chenab River. It is one of the top five rivers in terms of size through the Punjab region. It develops as a result of the confluence of the Chandra and Bhaga rivers. In particular, the Lahaul region of the Indian state of Himachal Pradesh is where they first appeared, in the highest parts of the Himalayas. The Chenab River flows through the Jammu region of the Indian state of Jammu & Kashmir. It then makes its way to the Indus River by crossing the Punjab plains in Pakistan after that.


Athara Hazari, also known by its Urdu name, serves as the 18-Hazari Tehsil's administrative hub. It is conveniently located on the Jhang-Bakhar Highway in the Punjab province of Pakistan's Jhang District.


The Trimmu Barrage is roughly 7 kilometers away. The rivers Jhelum and Chenab meet to the north of the town, and water flows from there to the Trimmu Barrage.


Pakistan was granted permission by the Indus Waters Treaty to obtain its water supply from the Chenab. India is allowed to use the water for things other than drinking, like generating power. In Pakistan, a sizable portion of the land is used for agriculture using water from the Chenab River. Additionally, it has a substantial network of connecting canals that transport its water to the Ravi River's course.



Name

The Rigveda (VIII.20.25, X.75.5) refers to the Chenab River as the Asikni (Vedic:) river. Because of this, people have always had the impression that the water is murky.[6][7] Additionally, the word Krishna appears in the Atharvaveda.[8] A more recent variation of Askikni is Iskamati (Sanskrit). Originally known as v - Akesnes in Ancient Greek, its name was eventually modified to Acesines.


The Sanskrit text of the Mahabharata refers to the river as Chandrabhaga. This is because the river is formed by the confluence of the Chandra and Bhaga rivers.[8][10] The ancient Greeks were also familiar with this name. It was known by several names among the ancient Greeks, including Sandrophagos, Sandabaga, and Cantabria.


Chandrabhaga subsequently became known only as "Chenab," illustrating the Persian influence on the language. Alberuni thought that such a thing might have happened in the early Middle Ages.


Course


The two most significant tributaries of the Chenab supply water to the town of Tandi in Himachal Pradesh, India. On the left, you'll find the Chandra, and on the right, the Bhaga.

The confluence of the Chandra and Bhaga rivers may be found in Tandi, which is situated 8 kilometers (5.0 miles) southwest of Keylong in the Lahaul and Spiti areas of the Indian state of Himachal Pradesh. The river's beginning is at this location.


The Bhaga River originates from the Surya Taal Lake in Himachal Pradesh, which is a few miles west of the Bara-lacha La pass. The Chandra River originates in the glaciers that are close to Chandra Taal and to the east of the same pass. Through this crossing, the two rivers' water flows in different directions. The Chandra River and Bhaga River both wind through confined gorges for distances of 115 and 60 kilometers, respectively, before coming together at Tandi.


The Chandra-Bhaga then travels through the Chamba district of the Himachal Pradesh state of India. After then, it traverses through the districts of Kishtwar, Doda, Ramban, and Reasi as well as Jammu itself when it crosses the Jammu division of Jammu and Kashmir. This river travels through the Pakistani region of Punjab before joining the Sutlej to form the Panjnad River.


History The Indians were already familiar with the river at the time of the Vedas. According to tradition, Alexander the Great established Alexandria on the Indus River around 325 BCE; this location is currently known in Pakistan as Uch Sharif, Mithankot, or Chacharan. This area is close to the spot where the Indus and Punjab Rivers meet to form the Panjnad River. The author of the book "Anabasis of Alexander," Arrian, cited Ptolemy Lagides as an eyewitness who claimed that Alexander crossed a river that was two miles wide.


Dams


The Salal Dam, which is adjacent to Reasi in Jammu and Kashmir, can produce a sizable amount of energy using water. Numerous dams have been built, are being built, or are scheduled to be built on the Chenab to enable the country to produce its own electricity.


The 900 MW Baglihar Hydroelectric Power Project is a hydropower facility close to the Ramban Salal Dam. A 690 MW hydroelectric power project is close by called the Reasi Dul Hasti Hydroelectric Plant. A power facility of the size of 390 MW is located in the Kishtwar District. A power plant called the Ratle Hydroelectric Plant is now being built at Drabshalla in the Kishtwar District. A tributary of the Marusadar River in the Kishtwar District is where the Pakal Dul Dam is planned to be built.

When finished, the Kiru Hydroelectric Power Project and the Kishtwar Hydroelectric Power Project are expected to have respective capacities of 540 and 624 megawatts.


All of these are regarded as "run-of-the-river" projects by the 1960 Indus Water Treaty. As part of the pact, Pakistan was given access to the Chenab River's water. Both "consumptive" uses like farming and drinking as well as "non-consumptive" uses like running electricity generators can be made of water in India. India is allowed to store a maximum of 1.5 billion cubic meters, or 1.2 million acre-feet, of water in storage. Salal, Baglihar, and Dul Hasti's three projects were thought to be capable of storing a total of 260 thousand acre-feet (320 million cubic meters) of water in 2011.


At the Marala Headworks, the entire Chenab River is visible.

Four headworks in Pakistan are situated on the Chenab River:


The Gujranwala District is home to Marala Headworks, Khanki Headworks, and Qadirabad. Marala Headworks is situated close to Sialkot. Headworks is situated in the Mandi Bahauddin neighborhood. The Trimmu Barrage is located in the Jhang neighborhood.
