The Ganga Basin is a large river basin in northern India, primarily formed by the Ganges River and its tributaries. It covers an area of about 1,086,000 square kilometers, making it one of the most fertile and densely populated regions in the world. The basin supports agriculture, industry, and various ecosystems, playing a crucial role in the livelihoods of millions. The Ganga River originates from the Gangotri Glacier in the Himalayas and flows through several states, including Uttarakhand, Uttar Pradesh, Bihar, and West Bengal, before emptying into the Bay of Bengal. The basin is not only vital for water resources but also holds significant cultural and religious importance for many communities in India.
