The dam wall is a double curvature arch dam with an uncontrolled ogee
spillway in the river section. An apron is provided at the toe of the spillway. A gallery system of two interconnected galleries in the dam body itself as well as five galleries into the foundation (two on the left and three on the right flank) provide drainage and pressure relief to the dam.
The main outlet works of the dam consists of an inlet structure on the left bank upstream of the dam wall. The inlet is controlled by a service gate. From the inlet a 1 890 mm diameter tunnel leads to a control room 91.44 m downstream of the inlet. The control room is accessed by a tunnel from the left bank downstream of the dam wall. In the control room the water flows through a 1 219 mm steel pipe.
