context_page_description: The Yamuna, is the second-largest tributary river of the Ganga and the longest tributary in India. Originating from the Yamunotri Glacier at a height of 6,387 metres on the southwestern slopes of Banderpooch peaks of the Lower Himalaya in Uttarakhand, it travels a total length of 1,376 kilometres and has a drainage system of 366,223 square kilometres, 40.2% of the entire Ganga Basin. It merges with the Ganga at Triveni Sangam, Prayagraj, which is a site of the Kumbh Mela, a Hindu festival held every 12 years.
  It crosses several states: Haryana and Uttar Pradesh, passing by Uttarakhand and later Delhi, and meeting its tributaries on the way, including Tons, Chambal, its longest tributary which has its own large basin, followed by Sindh, the Betwa, and Ken. From Uttarakhand, the river flows into the state of Himachal Pradesh. After passing Paonta Sahib, Yamuna flows along the boundary of Haryana and Uttar Pradesh and after exiting Haryana it continues to flow till it merges with the river Ganga at Sangam or Prayag in Allahbad. It helps create the highly fertile alluvial Yamuna-Ganga Doab region between itself and the Ganga in the Indo-Gangetic plain.
context_section_description: In 1909, the waters of the Yamuna were distinguishable as clear blue, when compared to the silt-laden yellow of the Ganges. However, due to high-density population growth and rapid industrialisation, Yamuna has become one of the most polluted rivers in India, and indeed in the world.The Yamuna is particularly polluted downstream of New Delhi, the capital of India, which dumps about 58% of its waste into the river. A recent study shows that there is 100% urban metabolism of River Yamuna as it passes through the National Capital Territory (NCT) of Delhi. The most pollution comes from Wazirabad, from where Yamuna enters Delhi
