Dirt fill dam on the river Ardon. The maximum height of the dam 39 m, length 300 m, the volume of the mound 1, 586 million cubic meters of soil. Dam slept from gravel and gravelly soils, has a core of impervious loams. During the construction of the initial draft of the dam has been changed - to reduce the height of the dam (the initial project it was supposed to be 79 m at a volume of 3,726,000 m³ mound of soil), a mound of gravel and gravelly soils in persistent prisms was partially replaced by a mound of raw stone from the mountain scree, which significantly increased the reliability of the dam. A feature of the dam is raised with respect to the normal podpopnomu water level in the reservoir (NPU) dam crest elevation (1708 m elevation at NEC 1690, 6 m, so that grfignya dam above the normal water level in the reservoir 17, 4 m), which provides dam safety in the event of a collapse in the reservoir of a large landslide or collapse. In addition, the construction of the dam allows increasing its height in the case of such a decision.



Main HPP building - open-shore.
