The Koshi Barrage is a sluice across the Koshi river in the Nepalese Mithila region that carries vehicular, bicycle, and pedestrian traffic between Madhesh Province and Koshi Province of Nepal. It is near the International border with India. It was built between 1958 and 1962 and has 56 gates.^[1] It was constructed after the Koshi Agreement was signed between the Government of Nepal and India on 25 April 1954.^[2][3] The barrage was designed and built by Joseph and Company Limited, India. The Koshi Tappu Wildlife Reserve is roughly 3–4 miles north of the barrage.

In August 2008, the eastern embankments of the Koshi Barrage collapsed, several miles north of the Nepal-India border. The resulting flood wiped out miles of fertile farmland in Nepal, covering it with a thick layer of river sand, and affected 53,800 Nepalese. It left 3 million people homeless in Bihar, India.^[4]

2017 flood

Every year several areas of Terai are affected due to the flood and blockage of this barrage. This affects mostly the Koshi region of Bihar (Supaul, Saharsa, Madhepura and Purnia). The Kosi River is known as the "Sorrow of Bihar" as the annual floods affect about 21,000 km² (8,100 sq mi) of fertile agricultural lands thereby disturbing the rural economy. The Koshi has an average water flow (discharge) of 2,166 m³/s (76,500 cu ft/s).^[5]
