It flows between Ganges and Yamuna rivers for 400 kilometres (250 mi) throughMuzaffarnagar district,Meerut district,Baghpat district,Ghaziabad district andGautam Buddh Nagar district before it joins Yamuna river at Sector-150,Noida.^[1] TheHindon Air Force Base of theIndian Air Force also lies on its bank in theGhaziabad district on the outskirts of Delhi.^[2]

TheKali river is a tributary of Hindon. Kali originates in the Rajaji Range ofSivalik Hills and travels about 150 kilometres (93 mi) passing throughSaharanpur,Muzaffarnagar,Meerut andBagpat districts, merges with Hindon River at Pithlokar nearSardhana. After that Hindon merges with theYamuna River in Noida. The Kali river is also highly polluted and adds to the pollution of the Hindon, as it passes through a populated and industrial belt ofUttar Pradesh.^[1]

NearSardhana lies the ancient Mahadev Temple that is believed to be dating from theMahabharata period, and where thePandavas prayed before leaving for theLakshagrih, the notorious palace made oflac byDuryodhana, at the confluence of the Hindon (previously known as Harnandi) and Krishna rivers (Kali River,Kali Nadi) atVarnavrat, the presentBarnava, and where the prince resided with their motherKunti.^[3]

AnIndus Valley civilization (fl. 3300–1300 BCE) site,Alamgirpur is located along the Hindon River, 28 kilometres (17 mi) fromDelhi.^[4]

During 1857–58, Ghaziabad city was a scene of fighting during theIndian Mutiny, when Indian soldiers in the Bengal Army that were under theBritish East India Company mutinied but soon turned into a widespread uprising againstBritish rule in India. The Hindon River, in particular, was the site of several skirmishes between Indian troops and British soldiers in 1857 including theBattle 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.

The industries of western Uttar Pradesh discharge their effluents, often with no treatment, directly into the Hindon River.^{[citation needed]} This heavy loading characterizes the presence of toxic contaminants and for the biological diversity of river ecology. Dissolved oxygen levels are zero throughout the length of this river.

But now many NGOs have come forward to rejuvenate this river. Abhiyans like Hindon Kali and Krishna Bachao Abhiyan are held by locals. NGOs with RWA are working to aware local and trying to remove solid non-biodegradable wastes like plastic from the river. Now, farming is reducing chemical fertilizes and pesticides near the flood plains.[1]
