Dak Chaliou Dams Hydropower info by Hobo Maps- Go to Hydropower Projects Page - - Home

Dak Chaliou 1 & 2 Hydropower projects are still in planning and precise locations are not available so we are using a single location for both projects at coordinates 15°24'26.9"N 107°24'25.9"E (15.407466, 107.407204) as seen in image below.

The Dak Chaliou 1 & 2 projects have a big problem with the diversion of upriver waters away from their locations by the Xekaman 3 HPP which has a 7 km tunnel that takes water from the Nam Pagnou (river) and reservoir southeast to their powerhouse downriver from the Dak Chaliou proposed sites. This diversion takes most of the Nam Pagnou flow and bypasses the Dak Chaliou proposed sites as shown on satellite image map below:

Not sure who the owners of the two projects will be.

Vientiane Automation and Solution Engineering (VASE) is involved with this project in the planning stage.

Dak Chaliou stats chart below for both projects.
