Planning: Kudnamsai Water Quality
Kudnamsai is one of several hundred thousand small communities in the lower Mekong Basin, located in the Nam Pong district of Khon Kaen Province, Northeast Thailand. The community lies on the Pong River, a tributary of the Mekong. Originating from the pristine mountain streams of Phukradueng National Park in Loei Province, the Pong flows across the upper northeast provinces of Thailand and combines with the Chi and the Mun Rivers to join the Mekong at Ubolratchatani.
The Pong channel in Khon Kaen Province is closely interconnected and regulated by Ubolratana, Nong Wai and Mahasarakham Dams. As such, the Pong does not flow naturally and the dilution capacity, water quality and volume of water available for use are dependent on the regulated dam flows.
Large industries, irrigated farmlands and cities compete for water abstraction to meet their daily and seasonal consumption. Located downstream of Ubolratana Dam, the largest northeast reservoir, Kudnamsai is one of the most highly competitive reaches of the Pong. The Kudnamsai villagers with traditional rice farm and fishery livelihoods lie within a large industrial precinct.
