Ecker Dam

The Eckertalsperre is a dam near Bad Harzburg in the resin, which was taken in 1942 in operation and Ecker and its tributaries dammed. It is used primarily for drinking water supply, flood control and power generation.

Technology

The dam has a gravity dam made ​​of concrete as a shut-off. It was used with a supplement of up to 300 mm grain size for the first time in Germany Rüttelgrobbeton. The storage space uses a section of the valley, which was carved out basin- like beneath a clear valley terrace of a glacial glacier. The Eckertalsperre has a mean annual discharge of 16 million cubic meters.

History and boundary layer

After Söse reservoir lake and the dam or the dam Ecker was the third modern dam building in the resin. In the upper catchment area of ​​the plug on the Brocken field annual precipitation of 1372 mm will be registered in the long-term average, reaching peak values ​​of 1700 mm. The reservoir thus receives the highest rainfall of all resin dams.

A low water levels made ​​by the dam barely because their catchment area covers only half of the springing in the resin flows.

The dam was planned for the increasing demand for drinking water in the region. This rose in the 1930s by the planned construction of the city of Wolfsburg and the growing population of the city of Braunschweig. The construction of the dam was the middle of World War II. That time several hundred foreign workers and prisoners of war were used for the construction work.

Currently, the division of Germany the German-German border ran right through the dam, the dam was accessible only about two-thirds of the west. The rest of the dam from the West separated by a wall with barbed wire. The dam is operated by the resin and water works whose access rights have been regulated to the dam and the waters during the division of the bilateral treaties. The frontier post on the barrier wall is still present.

Drinking water supply

The reservoir supplies drinking water to the cities of Braunschweig, Wolfenbüttel and Wolfsburg. The water is directed to the elevated tank Lewerberg in love Castle, where the drinking water arrives from the Grane. From there a line for Thieder Lindenberg and continues to the cities of Braunschweig and Wolfsburg.

The water of the plug is caused by the relatively huminsäurehältigen bog streams with a pH of 4.6 acidic. Also, it is low in nutrients and thus well suited for drinking water treatment. Below the dam the water is close to neutral.

Hydropower

The output of the plant below the dam is between 120 and 250 kilowatts, the annual work reached up to 900,000 kWh. In addition, the water force is at Lewerberg used and creates an electrical work years up to 500,000 kWh.

Tourism

The shut-off of the reservoir is included as No. 1 ( Ecker Dam Dam ) in the system of stamp locations of the Harz hiking pin. Lake and barrage are not accessible by car.
