It is drained by the Triyuga river flowing east to join the great Koshi River.

The mouth of the valley opens onto a 175 km (109 mi) rectangle of land where the Triyuga meets the Koshi river above the Koshi Barrage. It was designated the Koshi Tappu Wildlife Reserve in 1976, and is home to the last remaining population of wild Asian water buffalo in Nepal. The reserve is mostly wetlands, subject to seasonal flooding, but also includes some grasslands and small patches of riverine forest. It is a Ramsar Site.[2]
