Yamuna

Yamuna. The Yamuna is one of the most sacred and major rivers of India, originating from the Yamunotri Glacier in the Banderpoonch peaks of the Lower Himalayas in Uttarakhand. It is the largest tributary of the Ganges, with which it merges at the Triveni Sangam in Prayagraj, a site of immense spiritual importance. Flowing through several historically significant states and cities, including Delhi, Mathura, and Agra, its basin supports a vast population and a rich ecosystem, though it faces severe environmental challenges.

Course and tributaries

The river begins its journey at the Yamunotri temple near the Champasar Glacier in the Garhwal division of the Himalayas. It flows south through the scenic valleys of Uttarakhand, passing by towns like Hanuman Chatti and Rishikesh, before entering the plains at Paonta Sahib in Himachal Pradesh. Its major right bank tributaries include the Tons, which is its largest, the Chambal, the Sindh, the Betwa, and the Ken, all contributing significant water volume. Important left bank tributaries are the Hindon, which flows through western Uttar Pradesh, and the Sengar. The river's course is notably regulated by several barrages and dams, including the Tajewala Barrage (now replaced by the Hathni Kund Barrage) and the Okhla Barrage in Delhi.

Religious and cultural significance

In Hinduism, the Yamuna is personified as the daughter of the sun god Surya and the sister of Yama, the god of death, making bathing in its waters a rite to avoid a painful demise. The river is intimately associated with the life of the deity Krishna, who spent his childhood and youth along its banks in regions like Braj and the city of Mathura. Major festivals such as Chhath Puja and Yamuna Chhath are dedicated to its worship. The Kumbh Mela, the world's largest religious gathering, is held at the confluence with the Ganges in Prayagraj. Iconic monuments like the Taj Mahal in Agra and the Red Fort in Delhi are situated on its banks, underscoring its deep cultural imprint.

Environmental issues

The river, particularly after it passes through Delhi at the Wazirabad barrage, is considered one of the most polluted in the world. It receives enormous quantities of untreated sewage and industrial effluents from cities like Delhi, Mathura, and Agra, drastically reducing dissolved oxygen levels. Key pollutants include heavy metals from tanneries in Kanpur and pesticide runoff from agricultural lands in states like Haryana and Uttar Pradesh. The formation of toxic foam near Kalindi Kunj and the depletion of aquatic life are visible consequences. Government initiatives like the Yamuna Action Plan, launched in collaboration with the Japan International Cooperation Agency, and rulings by the National Green Tribunal have had limited success in reversing the damage.

Economic importance

The Yamuna Basin is a critical agricultural region, with its waters irrigating millions of hectares of farmland through an extensive network of canals like the Western Yamuna Canal and the Agra Canal. It is a vital water source for major urban centers, including the National Capital Territory of Delhi, which relies on it for a significant portion of its drinking water supply via the Chandrawal Water Treatment Plant. The river supports industries ranging from textiles in Panipat to tourism centered on the Taj Mahal. Hydropower is generated at projects in its upper reaches in Uttarakhand, such as those near Lakhwar.

History and mythology

Ancient texts like the Rigveda and the epic Mahabharata mention the river, then known as Yami. The area around its banks formed the heartland of the Indus Valley Civilization and later powerful kingdoms like the Maurya Empire and the Mughal Empire. The city of Indraprastha, the legendary capital of the Pandavas, is believed to have been located on its banks in present-day Delhi. Historical battles, including those during the Indian Rebellion of 1857, were fought near its course. The Mughal Emperor Shah Jahan famously built the Taj Mahal overlooking its waters, and the riverfront gardens of Agra Fort exemplify its historical integration into urban planning.
