RIVER YAMUNA
The Yamuna River is the Ganga River's
 largest tributary. In India, it is also revered as a sacred river. The 
Yamuna River flows from the Yamunotri Glacier at Banderpoonch peaks 
(38?59' N 78?27' E) in the Mussourie range in the lower Himalayas, at a 
height of around 6,387 metres above mean sea level in the district of 
Uttarkashi (Uttarakhand).
Yamunotri has a
 hot water pool, and the water is so hot that people prepare rice and 
potatoes by putting them in cloth bags and immersing the bag in the hot 
water. The Yamuna River travels through a succession of valleys in the 
lower Himalayas for about 200 kilometres before emerging into the 
Indo-Gangetic plains. The main valley is overshadowed in the upper 
levels by many hanging valleys created by glaciers.The river's gradient 
is strong here, and the erosive action of the river water has shaped the
 entire geomorphology of the valley. Yamuna takes water from numerous 
major streams throughout its 200-kilometer headwater length. The 
combined stream travels through the Shivalik range of hills in the 
Indian states of Himachal Pradesh and Uttarakhand before entering the 
plains near Dak Pathar in Uttarakhand, where it is regulated by a weir 
and redirected into a canal for power generation. The Mussourie 
spur-along, on the right bank of the Yamuna basin, leads to the 
sprawling hill station of Mussourie (also known as the Queen of 
Himalayas). 
The Satluj Yamuna link (SYL) canal, which connects Satluj and Yamuna, is being built here. This canal was supposed to transport Haryana's share of the Indus basin's 3.5 MAF of water. The state of Haryana has finished its share of the canal, but the state of Punjab has yet to finish its portion. The Punjab government is opposed to the construction of this canal. The Punjab legislature recently approved an act known as the Punjab Termination of Agreement Act 2004, which declared previous agreements null and void.
The Tons, Chambal, Hindon, Sarda, Betwa, and Ken rivers are significant tributaries of the Yamuna. Rishiganga, Uma, Hanuman Ganga, Giri, Karan, Sagar, and Rind are some of the Yamuna River's smaller tributaries. The main Yamuna and Tons rivers are nourished by glaciers that originate in the Great Himalayan range, specifically the Bandar Punch Glacier and its offshoot. Many minor streams in the Yamuna basin, including as the Chautang, Sahibi, Dohan, Kantili, Bapah, and Banganga, end up in the sandy regions.
