Hindon River, a tributary of Yamuna river, is a river in India that originates in the Saharanpur District, from Upper Shivalik in Lower Himalayan Range. The river is entirely rainfed and has a catchment area of 7, 083 km2.
It flows between Ganges and Yamuna rivers, for 400 km through Muzaffarnagar District, Meerut District, Baghpat District, Ghaziabad, Noida, Greater Noida before it joins Yamuna river just outside Delhi. The Hindon Air Force Base of the Indian Air Force also lies on its bank in the Ghaziabad district on the outskirts Delhi.
Kali river, which originates in the Doon Valley and travels about 150 km passing through Saharanpur, Muzaffarnagar, Meerut and Bagpat districts, merges with Hindon River, before it merges with the Yamuna River. The Kali river is also highly polluted and adds to the pollution of the Hindon, as it passes through populated and industrial belt of Uttar Pradesh.
These days the Ghaziabad Nagar Nigam has taken serious steps to beautify the river banks.
Near Sardhana lies the ancient Mahadev Temple that is believed to be dating from the Mahabharata period, and where the Pandavas prayed before leaving for the Lakshagrah, the notorious palace made of lac by Duryodhana, at the confluence of the Hindon and Krishna rivers (Kali River, Kali Nadi) at Varnavrat, the present Barnava, and where the prince resided with their mother Kunti.
In 1857 to 1858, the Ghaziabad city was the scene of fighting during the Indian Mutiny, when Indian soldiers in the Bengal Army that was under the British East India Company mutinied but soon turned into a widespread uprising against British rule in India. The Hindon River, in particular, was the site of several skirmishes between Indian troops and British soldiers in 1857 including the Battle of Badli-ki-Serai and today, the graves of the British soldiers and officers can still be seen. Ghaziabad’s place in Northern Indian history is assured by the birth of many freedom fighters who played a role in various revolutions all dedicated to the attainment of freedom for all who have lived – and are still living – there.
Hindon Vahini 
The industrial discharge their effluents of western Uttar Pradesh, often with no treatment, directly into the Hindon River. This heavy loading of industrial effluent discharge directly into the Hindon River places an intolerable burden on the river’s natural ability to assimilate pollutants. Use of the river for disposal of untreated human sewage is a primary cause of poor water quality within the river. The Hindon receives a high loading of degradable and non-degradable domesticly generated litter. The Hindon River waters has been evaluated for physical and chemical characteristics the presence of toxic contaminants and for biological diversity of river ecology. Dissolved Oxygen levels are zero throughout the length of this river. The Hindon Vahini, a river conservation wing of Paryawaran sachetak Samiti is organizing a mass movement to save and make pollution free Hindon under leadership of Environmentalist Vijaypal Baghel.
