. The dam is wide at its base and wide at its crest. The dam structure contains of concrete and the structure itself has a surface area of . The dam is slender in design and its horizontal arches are in an elliptical shape. The horizontal curvature of the dam decreases from the center of the dam towards its abutments and the curvature from the center of the arches increases from the crest down to the foundation. The thickness is constant with the exception of where the dam is received by its abutments; here it is thicker to reduce pressure on the rock. The strong rock can accept stresses of 70 kg/cm2. Vertically, the thickness of the dam increases from the crest down to the foundation and has a slight curve from the center towards the crest. This helps alleviate tensile stress for when the reservoir is not only full but empty. The dam's outlet works consist of two discharge pipes, capable of releasing up to each. One discharges into the original diversion tunnel and another is located at the base of the dam and discharges into the river valley below.
