[7] The dam is also the subject of protest due to the forced relocations and ecological/cultural impact its reservoir will have.

[8] The Darian Dam project was planned through studies to have a reservoir volume of one billion cubic meters, But in order to preserve the village of Hajij, respect the religious beliefs of the people, and preserve the historical monuments of the region, especially Imamzade Obaidullah Hajij, the height of the Darian Dam was reduced by 50 meters.

[9] One of the goals of building the Darian Dam was to reduce the inequality in the water consumption of the Sirwan and Diyala River in Iraq and Iran.

The decrease in the reservoir volume of the Darian dam in Iran caused the total reservoir volume of Iran's dams on this river to reach 440 million cubic meters, which is much less than the water consumption on the Iraqi side of this river.

[11] This issue has several times led to Iraqi officials blaming the Iranian side for the reduced flow of this river during the dry seasons of the year.
