It has a structural volume of 560,000 m3 (732,452 cu yd) and its crest lies at an elevation of 618.5 m (2,029 ft) above sea level.

When the reservoir is at flood level, the spillway has a discharge capacity of 13,240 m3/s (467,566 cu ft/s).

The reservoir's surface area is 29 km2 (11 sq mi) and at full pool, it lies at an elevation of 612.5 m (2,010 ft).

The dam's power station is a run-of-the-river type and uses the active storage in the reservoir which can draw the lake down 30 m (98 ft) from full pool.
