Oredezh

The Oredezh (Russian: О́редеж) is a river in Volosovsky, Gatchinsky, and Luzhsky Districts in the south-western part of Leningrad Oblast, Russia, a right tributary of the Luga.

The source of the Oredezh is located in Lake Kyurlevsky Karyer in the eastern part of Volosovsky District.

At the eastern edge of Vyritsa it sharply turns to the south and accepts the Suyda from the left.

Urban-type settlements of Siversky, Vyritsa, and Druzhnaya Gorka lie in the basin of the Oredezh.

A part of Mshinskoye Boloto Zakaznik lies in the basin of the Oredezh, west of the river course.
