Sapta Koshi River is 720km long with an area of 74,500 square kilometers.

This wildlife reserve provides habitat for hog deer, spotted deer, wild pig, blue gaur, smooth-coated otter, jackal, 485 species of birds, 114 species of a water bird, 200 species of fish, 24 species of reptile, 11 species of amphibian and many more.
Koshi Tappu is mainly well known for bird watching. Now, since 2009, it is also getting popular for Gangetic dolphin watching.Gangetic Dolphin is commonly known as “Susu” as during the process of breathing, they produce that particular sound. This Gangetic Dolphin can’t breathe in the water and therefore, must surface every 30-120 sec. As per the research, the number of Dolphins are decreasing in Sapta Koshi River.
