DAM AND RESERVOIR

The Project reservoir will be formed by the construction of a 39 m high gravity dam with a crest length of 325 m across the Nam Theun, plus 13 small earthwork saddle dams along the west bank of the reservoir. A spillway and stilling basin have been specially designed for the purpose of reservoir level control. The Sponsors and independent consultants have extensively reviewed the underlying geology of the construction and reservoir sites. The basic geological structure of the Project areas is favourable to the undertaking of major civil works and proper completion and impounding of the reservoir.
