Hali Dam, Gravity dam in Makkah Province, Saudi Arabia

Hali Dam is a gravity dam spanning Wadi Hali with substantial dimensions that create a large water storage basin for the region. The structure holds water year-round and supplies the surrounding area with resources for farming, drinking water, and groundwater management.

Construction of the dam began in the early 2000s under the Ministry of Water and Electricity, completing a major infrastructure project for the region. This work represented a modern advancement in water management for the western part of Saudi Arabia.

The dam has been central to agriculture and settlement in the Al-Qunfudhah Governorate, helping communities develop while protecting villages from seasonal flooding. Local farmers and residents depend on the water supply for their daily work and livelihoods.

The dam lies about 14 km east of Keyad in Mecca Province, reached from the road serving Wadi Hali. The crest carries a concrete bridge built from pre-stressed slabs, and the 168 m spillway runs along the top of the structure. The surrounding area is hot and arid, so carry water and sun protection.

The spillway at the dam crest is 168 m long and carries a concrete bridge built from pre-stressed slabs, so the overflow channel doubles as a road across the top of the dam. The dam itself is 384 m long and 95 m high.
