There are six inspection corridors in the dam that monitor the dam. The dam wall has both a bottom outlet and a flood relief . A maximum of 9,000 m³ / s can be discharged via the flood relief.
Reservoir
When fully blocked , the reservoir extends over an area of around 15 km² and holds around 250 million m³ of water; This makes it the second largest reservoir in terms of volume in Saudi Arabia (after the reservoir of the König Fahd Dam ). The catchment area of the wadi up to the dam is 4,843 km².
