The Derbendikhan Dam is a critical multi-purpose dam located on the Diyala River in the Sulaymaniyah Governorate of northeastern Iraq. Constructed between 1956 and 1961, it is designed as a rock-fill dam with a central clay core. The primary functions of the dam include regulating water for agricultural irrigation, generating hydroelectric power, and providing flood protection for downstream communities. Lake Derbendikhan, created by the dam, serves as a vital water reservoir and a significant recreational area for the surrounding region. The integrated hydroelectric station provides renewable energy to the Kurdish power grid. In recent years, the dam has faced substantial challenges, most notably a powerful earthquake in 2017 that caused structural damage and necessitated extensive emergency repairs. Despite these setbacks, the dam remains an indispensable component of Iraq's national infrastructure, particularly for the water security of the Diyala Governorate. Water management at Derbendikhan is also a key topic in cross-border negotiations with neighboring Iran, as the headwaters of the Diyala River originate across the border.
