Barrier structure
The barrier structure is a combination of arch dam and pier dam made of concrete (multiple arch dam with 5 arches) with a height of 65 (or 72) m and a crown length of 470 m. The top of the wall is at a height of 270 m above sea level .
The dam wall has a flood relief , through which a maximum of 5,400 or 6,000 m³ / s can be discharged.
Reservoir
With a maximum storage target of 270 m, the reservoir extends over an area of around 14.72 (or 13) km² and holds 267.7 (or 182, 200 or 300) million m³ of water. With an average storage target of 250 m, the surface is 7.7 km². The average annual inflow into the reservoir is around 150 or 174 million m³; the minimum annual inflow is 37, the maximum 853 million m³.
power plant
The Mellègue power plant has an installed capacity of 11 MW . The average annual production is 17 (or 5) million kWh .
