The architecture of the rolled concrete dam is an attraction for engineers.

Roller-compacted concrete - (RCC) or rolled concrete is a special blend of concrete that has the same ingredients as conventional concrete but in different ratios.

The dam was constructed with rollcrete.

Roller-compacted concrete, sometimes called rollcrete, is a low-cement-content stiff concrete placed using techniques borrowed from earthmoving and paving work.

It was the first arch gravity Roller Compacted Concrete (RCC) dam in the world and comprises almost 64 600 m3 rollcrete and 14 200 m3 concrete with a gross storage capacity of 137 million m3.
