Diyala Weir

Diyala Weir is a diversion dam spanning the Diyala River that controls water flow for regional irrigation needs. The structure directs flow into two main canal systems that serve agricultural areas downstream.

This structure was designed and built between 1966 and 1969 by international engineers to modernize regional water management. It emerged as part of a larger agricultural development initiative across Iraq.

The Diyala Weir received recognition through its appearance on Iraqi postage stamps, marking its position as a central element of regional infrastructure.

Visiting this site works best during daylight hours when the structure and surrounding landscape are clearly visible. Early morning offers the clearest light for observing both the weir and the canal systems extending from it.

The weir includes specially engineered road bridges capable of supporting heavy vehicles such as tanks. This dual-purpose design reflects how the infrastructure was planned to serve both civilian and military needs.
