Ravi River :
Ravi river is one of the most important river of Himachal Pradesh.
Ancient name of river Ravi is 'Irawati' and 'Parushini'.
It originates from "Bara-Banghal" in kangra district from 'Badal' and 'Tantgiri' glaciers. From Bara Banghal it starts travelling towards Chamba. Baira Siul, Saho, Budhgil are its tributaries in Chamba district. Length of river is 158 km approx. in Himachal. And its total length is 720km. ( India-Pakistan )

* Baira river : It rises from Pir Panjal range.
* Siul river : It rises from Dhauladhar and Pir Panjal ranges near HImachal Pradesh And J&K border.
Both Baira And Siul river joins and form a single river 'Baira Siul'
At Chamba Town Baira Siul Joins Ravi . So Chamba Town is between two rivers > Ravi & Baira-Siul.
Ravi river flows through the base of Dalhousie Hills.
Ravi river separates 'Pir Panjal' from Dhauladhar Range. Its flow is very fast as it flows westwards. Ravi merges with Chenab in Pakistan. The water of the river Ravi drains in the Arabian Sea (Indian Ocean) through the Indus rier in pakistan.
More About Ravi :
Under the Indus Water Treatyof 1960, the waters of the Ravi and five other rivers are divided between India and Pakistan. Subsequently, the Indus Basin Project has been developed in Pakistan and many inter-basin water transfers, irrigation, hydropower and multipurpose projects have been built in India. The main Ravi River flows through the base of Dalhousie hill, past the Chamba town. It is at an elevation of 856 metres (2,807 ft) (where a long wooden bridge existed to cross the Ravi River). It flows into the south-west, near Dalhousie and then cuts a gorge in the Dhauladhar Range, before entering the Punjab plain near Madhopur and Pathankot. It then flows along the Indo–Pak border for 80 kilometres (50 mi) before entering Pakistan and joining the Chenab River. The total length of the river is about 725 kilometres (450 mi).
Ujh River is another major tributary of the Ravi River. Its source is in the Kailash mountains at an elevation of 4,300 metres (14,100 ft), close to the Bhaderwah Mountains in Jammu district. After flowing for 100 kilometres (62 mi), it joins Ravi at Nainkot in Pakistan.
As the Ravi flows past Lahore in Pakistan (26 kilometres (16 mi) below Amritsar in India) it is called "The river of Lahore" since that city is on its eastern bank. After passing through Lahore the river takes a turn at Kamlia and then debouches into the Chenab River, south of the town of Ahmadpur Sial. On its western bank is the town of Shahdarabag with the tomb OF Jahangir and the Tomb of Noor Jahan.
The Hydropower potential of Ravi River system has been assessed as 2294 MW. The hydropower potential developed since the 1980s is through installation of Baira Suil Hydroelelectric Power Project of 198 MW capacity, the Chamera-I of 540 MW capacity commissioned in 1994, the Ranjitsagar Multipurpose Project (600 MW) completed in 1999 and the Chamera-II of 300 MW capacity in the upstream of Chamera-I commissioned in 2004. As the Ravi river is located at lower level, Indus, Jhelum and Chenab rivers water can be diverted to this river for harnessing huge hydro power potential.
- Multipurpose development
The major multipurpose project (irrigation, hydropower, food development of fisheries Tourism and so forth) built on the river is the Ranjit Sagar Dam (also known as Thein dam as it is in Thein village). The left bank is in Punjab and the right bank is in Jammu and Kashmir. It is located on the main stem of the Ravi River, about 24 kilometres (15 mi) upstream of Madhopur Headworks (built during pre-partition time). The project is an outcome of the development plan conceived for the use of the waters of three eastern rivers allocated to India under the Indus Treaty, namely the Sutlej, the Beas and the Ravi, for irrigation, hydropower generation and other consumptive uses.
A proposal for building a storage dam on the Ravi River was initially planned in 1912, envisaging a 61 metres (200 ft) high dam. A committee later conducted a survey of the area, but it was not until 1954 that geologists fully inspected the project area. In 1957, a storage Dam was proposed on the Ravi River for irrigation purposes only. The power generation aspect was not considered then. It was only in 1964 that the project was conceived for multipurpose development and submitted to Government of India for approval. Finally, in April 1982, the project was approved for construction by the Government of India.
The project, as built now, has a 160-metre (520 ft) high earth gravel shell dam with a gross irrigation potential of 348,000 hectares (860,000 acres) of land and power generation of 600 MW (4 units of 150 MW capacity each).
