Weigyi dam on the Salween River, Karen and Karenni state, Myanmar

Most of the electricity would be exported to Thailand. The plans for the massive 4,500 MW dam on the Salween River in Karen and Karenni state are contested through strong opposition from civil society groups.


The Salween River (also known as Thanlwin or Nu River) originates in the Tibetan Plateau and flows through China, Myanmar and Thailand into the Andaman Sea. Being one of the few remaining largely free flowing rivers, the river ecosystem supports a unique biodiversity and is home to millions of people from many different ethnic groups. The Weigyi dam is a hydropower project proposed on the Salween River in Karen and Karenni state. It has provoked large civil society concerns over social and environmental impacts as well as potential human rights abuses [1,2,3,4]. The dam is part of a series of hydropower projects planned on the Salween River in Myanmar  (see related conflicts, below).

Project Details and Actors
Project DetailsAccording to the Burma Rivers Network [1], and a report by KDRG [3], the dam specifications are as follows:

Height: 168 meters (maximum height of water level of 220 meters)

Installed capacity: 4,540 to 5,600 MW (see also [4])

Reservoir size: 64,000 ha [see 3 for how estimates were calculated by KDRG]

Companies involved: Myanmar Electric Power Enterprise (Myanmar); Electricity Generating Authority of Thailand (EGAT); possibly also Chinese companies Sinohydro Corporation; China Southern Power Grid Company and China Three Gorges Project Corporation [see 1].

In an article from 2003, the World Rainforest Movement reported an estimated construction cost of USD 6 billion [6].

Environmental ImpactsPotential: Biodiversity loss (wildlife, agro-diversity), Floods (river, coastal, mudflow), Food insecurity (crop damage), Loss of landscape/aesthetic degradation, Deforestation and loss of vegetation cover, Surface water pollution / Decreasing water (physico-chemical, biological) quality, Large-scale disturbance of hydro and geological systems, Reduced ecological / hydrological connectivity, Groundwater pollution or depletion
Health ImpactsPotential: Malnutrition, Mental problems including stress, depression and suicide, Violence related health impacts (homicides, rape, etc..) , Other Health impacts
OtherEthnic groups will lose access to traditional medicine and herbal plants through flooding of the area [3]
Socio-economic ImpactsPotential: Displacement, Increase in violence and crime, Loss of livelihood, Loss of traditional knowledge/practices/cultures, Militarization and increased police presence, Specific impacts on women, Violations of human rights, Land dispossession, Loss of landscape/sense of place, Other socio-economic impacts
OtherLoss of traditional river trade routes, used by ethnic groups [3] Dam construction in Myanmar comes often with militarization of regions, which in turn has frequently caused human rights abuses, including sexual violence against women [3,4].
Project StatusProposed (exploration phase)
Pathways for conflict outcome / responseStrengthening of participation
Do you consider this as a success?No
Why? Explain briefly.The plans for the dams are still there. So far it only has been delayed, but not cancelled.
