2. Right-Bank Tributaries: Originating primarily from the Peninsular plateau.

 

Major Left-Bank Tributaries

1. Yamuna River
• Origin: Yamunotri Glacier in the Himalayas, Uttarakhand.

• Major Cities: Delhi, Mathura, Agra.
• Confluence Point: Sangam in Allahabad (Prayagraj), Uttar Pradesh.
2. Ghaghara River
• Origin: Tibetan Plateau (near Lake Mansarovar).
• Significance: Provides a significant water volume to the Ganga.
• Confluence Point: Chhapra, Bihar.
3. Gandak River
• Origin: Nepal Himalayas (Dhaulagiri range).
• Significance: Supports irrigation and has cultural importance.
• Confluence Point: Hajipur, Bihar.
4. Kosi River
• Origin: Tibet and Nepal (various Himalayan sources).
• Significance: Known as the "Sorrow of Bihar" due to frequent flooding.
• Confluence Point: Katihar, Bihar.
5. Ramganga River
• Origin: Doodhatoli ranges in Uttarakhand.
• Significance: Major source of irrigation.
• Confluence Point: Near Kannauj, Uttar Pradesh.
6. Mahananda River
• Origin: Darjeeling Hills, West Bengal.
• Significance: A vital river for northern West Bengal and Bihar.
• Confluence Point: Near Katihar, Bihar.

 

Major Right-Bank Tributaries

1. Son River
• Origin: Amarkantak Plateau, Madhya Pradesh.
• Significance: Known for its straight flow and rich mineral deposits.
• Confluence Point: Near Patna, Bihar.
2. Damodar River
• Origin: Chota Nagpur Plateau, Jharkhand.
• Significance: Referred to as the "Sorrow of Bengal" historically due to floods; now tamed by the Damodar Valley Project.
• Confluence Point: Joins the Hooghly River.
3. Punpun River
• Origin: Chota Nagpur Plateau, Jharkhand.
• Confluence Point: Near Patna, Bihar.
4. Chambal River

Other Notable Tributaries

• Tons River: Merges with the Ganga in Uttarakhand.
• Rihand River: Major source for the Rihand Dam in Uttar Pradesh.

 

Importance of the Tributaries

1. Agriculture: Provide irrigation for millions of hectares of farmland.
2. Hydropower: Many tributaries are harnessed for electricity generation.
3. Biodiversity: Support rich aquatic ecosystems.
4. Cultural Significance: Many tributaries hold religious importance in Hinduism.

Conservation Challenges

1. Pollution: Industrial discharge and urban waste.
2. Flooding: Frequent in tributaries like Kosi and Damodar.
3. Climate Change: Affecting flow patterns and glacial sources.

Efforts are underway under the Namami Gange Programme to restore and maintain the ecological health of the Ganga and its tributaries.
