Mouth of the Sakae Krang River

Sakae Krang River basin is located in the Central Plain of Thailand. It flows from northwest to southeast from Mae Wong district and Lard Yao district in Nakhon Sawan Province. It then joins Khlong Pho at Sawang Arom district in Uthai Thani province and then joins Huai Thap Salao at Thap Than district of the same province. The river finally joins the Chao Phraya River at Krok Phra district in Uthai Thani province. The high and steep mountainous upstream area of Sakae Krang river and the flat downstream area before joining the Chao Phraya river causes flash flooding every rainy season. The Tha Chin River basin is divided into 5 sub-basins. Most of the areas in the river basin are field crop and paddy field. The water resource is utilized mainly for paddy irrigation. Thap Salao Dam is the only existing impounding reservoir in the basin. The source of the Sakae Krang river is in a mountain watershed in the north and central regions of Thailand in Uthai Thani, Kamphaeng Phet and Nakhon Sawan provinces. The people living in the river basin grow crops for their livelihood and they have their own local dialects.
