The dam will be approximately 1780 m long and 160 m high and will have a concrete volume of 10.5 Mm3, creating a reservoir of about 75 billion m3. The dam has left and right banks with a central low block housing an ungated spillway.
• The Saddle Dam raises the watershed from e. 600 m a.s.l. up to 646 m a.s.l.. The dam follows the morphology of the watershed with a crest length of approximately 5 km and an ungated emergency spillway on the right bank. The maximum dam height is 50 m.
• The two powerhouses of the open air type are situated immediately downstream of the dam on the left and right banks of the river.
