But experts say this ecotourism paradise, known as the "Four Thousand Islands" region, could soon be irreversibly damaged by the construction of a hydro-electric dam recently announced by Laos, only a few kilometres from the renowned Khone Waterfall, a major tourist attraction.

The communist government notified the Mekong River Commission [MRC] on September 30 of its plans to launch construction of the Don Sahong Dam next year. The 260 megawatt dam would be Laos' second Mekong hydropower project.

The commission is the multi-nation body that supposedly oversees development on the vital waterway.

Concerns about the new dam were raised this week in Bangkok at a forum of 103 Thai NGOs campaigning against it.

Photo-journalist Suthep Kritsanavarin, who has documented the communities of the region for National Geographic magazine told the forum: "If the water level in the Hou Sahong [channel] increases [to support the dam], we will see a decrease in other areas, including the Pha Pheng [Khone] Waterfall.
