Without the Ramganga river there would be no Corbett. It is the largest of the precious few perennial sources of water in the Park. In fact, for a brief period (from 1954 to 1957) the Park was known as Ramganga National Park.

A rain-fed river originating near Gairsain in the Lesser Himalayas, the Ramganga traverses more than 100 km before entering Corbett near Marchula. Inside the Park it flows roughly from east to west for 40 km till Kalagarh where it enters the plains. During this run through the Park it gathers waters from the Palain, Mandal and Sonanadi rivers.

Dam on the Ramganga at Kalagarh (built in the mid-1970s) forms a reservoir of about 80 sq. km. area, the backwaters of which reach till Dhikala. Downstream from Kalagarh the river meanders for another 300 km through the Indo-Gangetic plains and finally drains into the Ganga near Farrukhabad in Uttar Pradesh.

The Ramganga is inhabited by key aquatic species like mahseer fish, the endangered gharials, mugger crocodiles, otters and turtles. Many species of birds, like kingfishers, fish-eagles, terns and storks depend on the Ramganga. During winters the Ramganga reservoir attracts many migratory bird species, especially waterbirds from Europe and Central Asia
