Dudh Koshi (दुधकोशी नदी, Milk-Koshi River) is a river in eastern Nepal.

Koshi river system[edit]

The Kosi River, or Sapt Koshi, drains eastern Nepal. It is known as Sapt Koshi because of the seven rivers which join together in east-central Nepal to form this river. The main rivers forming the Koshi system are – the Sun Kosi, the Indravati River, the Bhola Koshi, the Dudh Koshi, the Arun River, Barun River, and Tamur River. The Dudh Kosi river originates from the high-altitude areas of Mt Everest (8848 metres) and the snow and glacier melt contributes significant portion of streamflow, especially during the dry season.[1] The combined river flows through the Chatra Gorge in a southerly direction to emerge from the hills.[2][3]


The river drains the Mount Everest massif, the highest peak in the world.[2] It begins just east of Gokyo Lakes and flows south to Namche Bazaar. Continuing south, the Dudh Koshi exits Sagarmatha National Park and passes to the west of Lukla. The Lamding Khola joins the Dudh Koshi to the southwest of Surkya and continues its southerly course to Harkapur, where it joins the Sun Kosi.[4]


The river is characteristic of extreme white water and normally cannot be used for watersports. The first kayak trip was made in 1976 by a British expedition under the leadership of Mike Jones.
