. The dam's crest is wide with a base width of while the volume of concrete in the dam structure is. The dam sits at the head of a catchment area and creates a reservoir with a capacity. The reservoir's surface area is and its length. The dam has a main and auxiliary spillway. The main spillway is controlled by two radial gates and has a maximum discharge capacity of. The auxiliary spillway is uncontrolled and has a discharge capacity of.
