The location where Irpin' enters the Dnieper river falls into the Kyiv Reservoir which the Dnieper forms because of the Kyiv Hydro-Electric Power Plant dam. Thus, the Dnieper water level at this location is lifted artificially by about 6.5–7 meters above the natural level. Therefore, the water of Irpin' is pumped into the Kyiv Reservoir by powerful electrical pumps, making Irpin' the river that literally flows upwards.

The lands around Irpen' were the heartland of Kyivan Rus and the chronicles mention the river in connection with several important historic events, such as the Battle on the Irpen' River of 1321 in which the Grand Duke of Lithuania Gediminas (Gedemin) gained control over the lands of what is now central Ukraine.
