The once-mighty Mekong river has been reduced to a thin, grubby neck of water in stretches of northern Thailand -- record lows blamed on drought and a recently completed dam far upstream.
The USD 4.47 billion Thai-owned Xayaburi hydro-electric power plant went into operation this week in Laos after years of warnings over the potential impact on fish flow, sediment and water levels on a river which feeds tens of millions.
Along parts of Thailand's northeastern border at Loei, the kilometre-wide (3,300-foot) river has shrivelled to a few dozen metres, with boulders and bedrock encasing muddy pools of water.
From above, the encroaching banks of Laos and Thailand are now a thread of water apart, restricting fishing grounds to a slim channel.
Fishermen blame a combination of this year's weak monsoon and the Xayaburi dam, around 300 kilometres (185 miles) to the north.
"I don't want any more dam construction," said fisherman Sup Aunkaew, who tossed a meagre catch into his boat, adding that the fish spawning habits have been "confused" by the unseasonally low water levels.
