Water plays a vital role in sustaining the rich avifaunal diversity of Corbett National Park. The incredible range of flora and fauna found here largely thrives because of the powerful rivers that shape the park’s ecosystem. The Ramganga River (West) along with its key tributaries—Sonanadi, Palain, and Mandal—serves as the primary lifeline of Corbett’s hydrology. Alongside, the Kosi River flows near the park and acts as an important water source for the adjoining regions. A large section of Corbett’s wilderness lies close to the banks of River Kosi. These water channels nurture a vast and varied aquatic habitat across the park. The park’s wildlife depends heavily on these rivers, especially during dry months, as they provide essential drinking water. The rivers flowing in and around Jim Corbett National Park include:
