Hindon River — Western UP’s Polluted Stream
| Parameter | Detail |

| Origin | Upper Shivalik Hills (Saharanpur) |
| Length | ~355 km |
| Flows through | Saharanpur, Muzaffarnagar, Shamli, Baghpat, Meerut, Ghaziabad, Noida |

| Pollution | Industrial effluents from NCR, sugar mills, paper mills |
| Status | Classified as one of the most polluted rivers in India by CPCB |
Chambal River
| Parameter | Detail |
|---|---|
| Origin | Janapav Hills near Mhow, MP |
| Total length | ~960 km |
| States | MP → Rajasthan → UP (border) |
| Joins Yamuna | Near Etawah/Auraiya border |
| Key feature | Chambal ravines (badlands) — severe soil erosion |
| Dams | Gandhi Sagar, Rana Pratap Sagar, Jawahar Sagar (all in Rajasthan) |
| Wildlife | National Chambal Sanctuary — gharial, river dolphins, mugger crocodiles |
The Chambal is considered one of India’s cleanest rivers because it flows through sparsely populated ravine areas.
Western UP Drainage Pattern
Western UP has a distinct drainage character:
| Feature | Detail |
|---|---|
| Major rivers | Yamuna, Hindon, Kali (East & West), Krishna |
| Drainage direction | South to south-east |
| Soil | Alluvial (Khadar and Bhangar) |
| Terrain | Flat plains with ravines along Yamuna and Chambal |
| Agriculture | Sugarcane belt (Muzaffarnagar, Shamli, Baghpat) |
| Key concern | Groundwater depletion due to intensive farming and tube wells |
Kali River (East) — flows through Meerut, Bulandshahr; heavily polluted by industrial waste. Kali River (West) — flows through Muzaffarnagar; equally degraded.
Yamuna Pollution Crisis
The Yamuna is among the most polluted rivers in the world, especially the Delhi-Agra stretch.
| Pollution Fact | Detail |
|---|---|
| Most polluted stretch | Delhi to Agra (~490 km) |
| Major pollutants | Domestic sewage, industrial effluents, agricultural runoff |
| Delhi’s contribution | ~80% of Yamuna’s pollution from Delhi alone |
| Impact on UP | Water unfit for drinking or bathing from Noida to Mathura |
| Cleanup efforts | Yamuna Action Plan I (1993), Phase II (2004), Phase III (ongoing) |
| Threat to Taj Mahal | Yamuna pollution and declining water levels affect Taj Mahal’s wooden foundations |
