Saptakoshi River Water Flow Increases with Monsoon

Sunsari. With the onset of monsoon, the water flow in Saptakoshi is continuing to increase. The water flow at Kosi Barrage reached 163,230 cusecs late on Wednesday, informed Deputy Superintendent of Police of Sunsari, Chandrabahadur Khadka. It is estimated that the flow in the river may increase further as it continues to rain in eastern Nepal.

Out of the 56 gates of Kosi Barrage, 21 gates have been opened. The barrage has a total of 56 gates, including 52 main gates and four canal gates.

The Kosi Barrage control room stated that a red light is turned on and a red flag is hoisted at Kosi Barrage as a sign of risk when the water flow exceeds 150,000 cusecs.

As the Saptakoshi, which appears calm during the dry season, becomes fierce with the onset of monsoon, this river attracts the attention of various areas in India as well as Nepal. Due to rainfall in the eastern hilly and terai regions during the months of Asar, Saun, and Bhadau, the water level in various rivers rises. The flow in Saptakoshi also increases, and the risk of inundation and erosion in areas around the river also increases.

The water of Tamor, Arun, Sun Koshi, Dudh Koshi, Tamakoshi, Bhote Koshi, and Indrawati rivers mixes in Saptakoshi. While the Saptakoshi fills with water during the monsoon, it appears filled with sand in many places during the dry season.
