The Karnali is a very long river. 



The Ghaghara is a huge and important river. It is known by many different names. In Tibet, it is called the Mapcha Tsangpo. As it flows through Nepal, people call it the Karnali River. The Karnali is the longest river in all of Nepal. 
The river begins its journey very high up. It starts in the glaciers of Mapchachungo in the Tibetan Plateau. This area is part of the northern slopes of the Himalayas. 


People have used this river for a very long time. In the past, the river was a busy path for travel. Steamers used the lower part of the river to move goods. People carried things like timber, sugar, and cotton on cargo boats. This was very common during the months of April, May, and June. 
Many amazing animals call this river home. The river is a very important place for the Gangetic dolphin. These are the largest freshwater mammals on the Indian subcontinent. They are an endangered species, which means they are at risk. 

The river is also used to help people grow food. In India, there is a large irrigation project. It uses the water from the Ghaghara and the Sarda rivers. This project is one of the largest in all of Asia. It uses a system of canals to move water to many districts. This helps farmers water their crops in many different areas. 
The Ghaghara is a massive perennial river system. It flows across several borders in Asia. In Tibet, the river is called the Mapcha Tsangpo. As it travels south through Nepal, it is known as the Karnali. 
The river begins in the high Tibetan Plateau. It originates in the Mapchachungo glaciers. These glaciers sit on the northern slopes of the Himalayas. The river starts at an elevation of about 5,000 meters. 
Many other rivers join the Karnali as it flows. The Seti River drains the western part of the catchment. It joins the Karnali in the Doti District. The Bheri River also joins the main flow near Kuineghat. This river rises in the western Dhaulagiri Himalaya. 

The river supports many unique and endangered species. The Gangetic river dolphin lives in these waters. These are the largest freshwater mammals on the Indian subcontinent. They are considered an endangered species on the IUCN Red List. 
Humans have used the river for many different purposes. In the past, the river was a major route for navigation. Steamers used the lower Ghaghara to move goods. People used cargo boats to carry timber, sugar, and cotton. The best time for this was during April, May, and June. However, the arrival of railways in the late 19th century changed things. Railways were faster and safer than river travel. Most waterways lost their importance as trade routes after that. Today, the river is used more for electricity and farming. A 900 MW hydroelectric project is planned for the Karnali.
In India, the river is vital for large-scale agriculture. The Sarda Sahayak Irrigation Project uses the Ghaghara and Sarda rivers. This project uses a structure called the Girija Barrage. This barrage is located in the Bahraich district. The system includes a long link canal. This canal connects the Girija Barrage to the Lower Sarda Barrage. This entire canal system is considered the largest in Asia. It provides irrigation to a massive area. It covers 14 districts and 168 blocks. This helps many farmers grow crops in the region. 
Nature also shapes the land around the river. The Karnali River exposes the oldest parts of the Sivalik Hills. Scientists have studied the siltstones and sandstones here. They found evidence of magnetic polarity in these rocks. This suggests the sediments were deposited between 16 million and 5.2 million years ago. The river also has many smaller tributaries like the Chhoti Gandak. The Chhoti Gandak is a groundwater-fed river. Its flow is controlled by heavy monsoon rains. When rain is very high, it can cause floods downstream. This shows how the river and the weather work together to change the landscape.
