Oder Reservoir

The Oder is a 56-kilometre-long (35 mi) river in Lower Saxony, Germany, and a right tributary of the Rhume. Its source is in the Harz mountains, near Sankt Andreasberg. It flows southwest through Bad Lauterberg, Pöhlde and Hattorf am Harz. The Oder flows into the Rhume in Katlenburg-Lindau.

Course

The Oder rises in the district of Goslar in the heart of the Harz Mountains. Its source is located in the southern part of the Brockenfeld about 1.3 km (0.81 mi) north of the Achtermannshöhe. The river's source is called the Odersprung or "Oder Leap."

On the Brockenfeld, which is close to the Odersprung, the rivers Abbe,

Große Bode, Ecker and Kalte Bode also have their respective origins. On its perimeter is the ancient Dreieckiger Pfahl

boundary stone.

After the Oder passed under the B 4 federal highway in Oderbrück [de] in east-west direction, it is impounded for the first time west of the village in the Oderteich, where it bends to the south. A few kilometres further downstream, the river is impounded for the second time not far southwest of Oder Valley Sawmill (Odertaler Sägemühle) by the barrage of the Oder Dam. Thereafter the river flows through Bad Lauterberg and leaves the Harz.

In Bad Lauterberg the Oder swings west, running through

from the east.
