The original confluence of the Irpin and the Dnieper is beneath the surface of the Kyiv Reservoir, which was formed by the dam for the Kyiv Hydroelectric Power Plant in the mid-1960s.

Ukrainian troops also opened the Kozarovychi dam on the second day of the invasion, to flood the Irpin basin, including houses in Demydiv.

Ecologists argue that the dams should not be rebuilt and that the wetland should be protected and restored.
