The dam is a Шаблон:Convert tall and Шаблон:Convert long gravity dam.[2] It is composed of Шаблон:Convert of concrete, Шаблон:Convert is roller-compacted concrete. The reservoir created by the dam has a capacity of Шаблон:Convert. To release water downstream, the dam has five Шаблон:Convert x Шаблон:Convert crest openings along with three mid-level openings and one bottom flushing outlet. With these openings, the design flood discharge capacity of the dam is Шаблон:Convert while the maximum is Шаблон:Convert.[1]
