The Muda River (Malay: Sungai Muda) is the longest river in Kedah, Malaysia.
Course
Sourced in Ulu Muda Forest in Sik region in northeastern Kedah, along the border with Thailand, the river meets the water needs of the states of Kedah and Penang. The river flows through much of Sik region, then entering the Baling region where it meets with the Ketil river, a left-bank tributary, at Kuala Ketil.
The Beris Dam, which was completed in 2004 at a cost of RM360 million, is used to regulate the flow of water along the Muda River basin to augment water available for irrigation of paddy or upland crops, for domestic and industrial water supply and other uses.
