Which Glacier is the Source of the Bhagirathi River?

Did you know one of India’s holiest rivers begins its journey high in the icy Himalayas? Long before it becomes wide and powerful in the plains, it starts as a narrow stream born among snow, rocks, and freezing winds.

The early flow of this river is not gentle at all. It rushes down steep mountain slopes, cutting through deep valleys and echoing loudly across silent peaks.

Pilgrims travel great distances every year to see this sacred origin point. For them, it is not just geography, but a place filled with faith, devotion, and ancient stories.

The source lies in a region where glaciers slowly move like frozen rivers. Even in summer, the air stays cold and patches of snow shine under the bright sun.

From this tiny beginning in the mountains, the river eventually grows into one of the most important waterways of northern India, supporting life, culture, and traditions along its long journey.

Which Glacier is the Source of the Bhagirathi River?

The Bhagirathi River originates from the Gangotri Glacier in Uttarkashi district of Uttarakhand.

The water comes out from a cave-like opening at the end of the glacier called Gaumukh. The word Gaumukh means “cow’s mouth” because the ice formation once looked like the mouth of a cow. From this icy opening, the first stream of the Bhagirathi starts flowing down the mountains.

• Height of source: about 13,200 feet (4,000 metres)
• Location: Gangotri region, Uttarakhand
• Mountain range: Garhwal Himalayas

This glacier is one of the largest in India and acts as a giant natural water tank that feeds the river throughout the year.

Journey of the Bhagirathi River

After emerging from Gaumukh, the river travels through narrow valleys and steep rocky paths in the Himalayas. The water flows very fast because it drops thousands of metres in elevation.

The Bhagirathi flows for about 205 kilometres in Uttarakhand before meeting another important river — the Alaknanda.

The Sacred Meeting at Devprayag

At Devprayag, the Bhagirathi and Alaknanda join together. From this point onward, the river is officially called the Ganga River.

So, although many streams contribute water, tradition considers the Bhagirathi the spiritual starting point of the Ganga.

Why the Gangotri Glacier is Important?

The Gangotri Glacier is not just a block of ice — it is a lifeline for millions of people.

• Source of the Ganga River System: The glacier ultimately supplies water to northern India’s most important river system, supporting agriculture, drinking water, and daily life.
• Cultural and Religious Significance: According to Hindu belief, King Bhagiratha prayed for centuries to bring the heavenly river to Earth. The river was therefore named after him.
• Environmental Importance: The glacier stores snow in winter and releases water slowly in summer, helping maintain river flow even in dry seasons.

However, the glacier is shrinking due to climate change, and the Gaumukh opening moves backward every year.

Major Tributaries of the Bhagirathi River

As the river flows down the mountains, many smaller rivers join it. Main tributaries include:

• Bhilangana River – the largest tributary, meets at Tehri
• Jadh Ganga (Jahnavi) – joins near Bhaironghati
• Kedar Ganga – meets at Gangotri town
• Asi Ganga – joins near Uttarkashi
• Jalandhari Gad and Kakora Gad – near Harsil

Among these, the Bhilangana River is the most important because it brings a large volume of water and forms the site of the Tehri Dam.
