The construction of the Oker Dam was undertaken by the Harz Waterworks between 1938 and 1942.[1] For this purpose, the valley roads were first relocated to the western and northern banks and the two road bridges ("Weißwasserbrücke" and "Bramkebrücke") were built. From October 1939, prisoners of war were also employed: in January 1941, 50 free workers and 400 prisoners of war from France worked on the construction site, who were replaced by Soviet prisoners from August 1941. Due to the harsh working conditions, ten prisoners of war died by the end of 1941; their graves are located in the Altenau cemetery.[9] Further Soviet dead were buried near the barracks camp from January 1942 onwards; the burial ground on the eastern bank of the Oker downstream of the Weisswasserbrücke is now flooded. Because of the war and the resulting change in priorities, construction was interrupted in April 1942 and the workers were used to build the Eder Dam.[10]

In 1573, another raft lock, the Small Julius Dam, was built upstream in the Gemkenthal. It was of the same design (a box weir approximately 10 meters high and 57 meters wide) and dammed an approximately one-kilometer-long artificial body of water. Both dams, the Large and Small Julius Dam, were destroyed by a severe flood on June 27, 1579.[7][8]

The structure was 17 m high and 49 m wide and consisted of a two-story stone box weir made of tree trunks that protruded from each bank into the middle of the river in a triangular shape. The boxes were filled with gravel and sand and sealed with moss. An additional story was added to the rear section, making the structure the equivalent of a five-story building. Three locking panels enabled it to function as a raft lock to regulate the discharge of water from the dammed Oker River.

In 1570, Duke Julius of Brunswick-Wolfenbüttel had a box-shaped dam built on the site of the present dam wall, about 30 meters downstream, the so-called Great Julius Dam. The dam served to float timber and firewood from the Harz Mountains downstream of the Oker River to his residence, Wolfenbüttel. A small artificial flood could be created by releasing the dammed water from a reservoir up to 1,320 meters long into the Oker River. In the 16th century, it was the largest artificial dam in Germany.[6]

The reservoir supplies drinking water to the cities of Braunschweig, Wolfenbüttel, and Wolfsburg. The water is piped to the Lewerberg reservoir near Liebenburg, where drinking water from the Grane Dam also arrives. From there, a pipeline leads to the Thieder Lindenberg and further to the cities of Braunschweig and Wolfsburg. The water of the Ecker River is relatively acidic, with a pH of 4.6, due to the humic acid-rich moor streams. It is also low in nutrients and therefore well suited for drinking water treatment.[3] The dam is not used for fishing, as most fish cannot tolerate the low pH.[5] Below the dam, the water is almost neutral.

The Ecker Dam (sometimes also called the Ecker Reservoir) is a dam near Bad Harzburg in the Harz Mountains, which was commissioned in 1943[1] and impounds the Ecker River and its tributaries. Operated by Harz Waterworks, the facility serves to supply drinking water, protect against flooding, increase low water levels, and generate energy.[2] Source: https://de.wikipedia.org/wiki/Eckertalsperre
