Oker Dam

The dam is in the shape of an arch . It is 75 m high, 260 m long, can impound up to 47 million m³ of water and provides hydropower, flood protection and water regulation at times of low water. It is also used indirectly for the production of drinking water. Its average annual discharge is 75 million m³. The hydro-electric power station at Romkerhalle is fed by the Oker Reservoir.

The construction of the Oker Dam was begun by Hr. Press in the years 1938 to 1942 and then completed between 1949 and 1956. Its completion became pressing following the devastating floods in Wolfenbüttel and Brunswick in the winter of 1946/47 when there were heavy falls of snow. Before work started the small hamlet of Schulenberg in the valley had to be abandoned; it was rebuilt above the reservoir.
