Ganges River
Sacred river of northern India

The Ganges River is a 2,525-kilometer trans-boundary river flowing through India and Bangladesh, considered sacred in Hinduism. It supports one of the world's most densely populated river basins and hosts diverse aquatic ecosystems despite severe pollution challenges.
Overview
The Ganges River, known as Ganga in India, originates from the Gangotri Glacier in the Indian Himalayas at an elevation of approximately 4,000 meters and flows southeast across the northern plains of India before entering Bangladesh and emptying into the Bay of Bengal through the world's largest river delta, the Sundarbans. The river traverses through the states of Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, and West Bengal in India, serving as a lifeline for over 400 million people who depend on it for drinking water, agriculture, and fishing. The Ganges basin encompasses approximately 1,080,000 square kilometers and supports exceptional biodiversity, including the critically endangered Ganges river dolphin, gharial crocodiles, and numerous species of fish, turtles, and waterbirds. The river system includes major tributaries such as the Yamuna, Ghaghara, Gandak, and Kosi rivers, creating a complex network of aquatic habitats ranging from cold mountain streams to vast floodplains and mangrove forests. Despite its ecological and cultural significance, the Ganges faces severe environmental challenges including industrial pollution, agricultural runoff, sewage discharge, and overextraction of water. The river is central to Hindu religious practices, with major pilgrimage cities like Varanasi, Haridwar, and Allahabad (Prayagraj) located along its banks. The Indian government has launched multiple initiatives, including the Namami Gange Program, to clean and conserve the river. The Ganges delta, shared with Bangladesh, forms one of the most productive agricultural regions in the world and includes the Sundarbans, the largest mangrove forest on Earth and a UNESCO World Heritage Site. The river's seasonal flooding patterns have historically enriched the soil and supported intensive agriculture, though dam construction and climate change are altering these natural cycles.
