Wendefurth Dam
The dam Wendefurth in the resin is a built in 1957-1964, from the dam, hydropower plant and dam existing dam at Wendefurth in the district of Harz, in Saxony- Anhalt, which is downstream of the main dam Rappbodetalsperre.
Your 43.5 m high dam dams especially the Bode and their inflow Rappbode on for about 78 ha large reservoir Wendefurth. With additional storage facilities, such as the Rappbodetalsperre, the dam serves Rappbode reservoir system for flood protection in the eastern Harz, where it protects the lying below their dam especially in Bode villages. It also serves as a reservoir for the pumped storage plant Wendefurth. In addition, her dam is used for bathing and fish breeding.

Geographical location
The Wendefurth Dam is located in the Lower Harz Harz nature park / Saxony- Anhalt. At the Bode it is located between the respective somewhat distant villages Elbingerode the west-northwest, Blankenburg in the north- northeast, east-northeast in the valley and Hasselfelde in the southwest.
Dam
Location
The shut-off of the dam stands as a gravity dam just west of the hamlet Thaler Wendefurth. On top of the wall in an incipient Wendefurth infrastructure which may be entered by visitors passes.
History
The construction of the dam Wendefurth began in April 1957 and were suspended in November 1957 because the first Pohl dam ( 1958-1964; during Poehl, Vogtland, Saxony ) and had to be completed then the Rappbodetalsperre (especially 1952-1959 ). Work continued in October 1959 and completed in December 1964. The impounding did not begin until 1967, there's ongoing work on the dam connected to the pumped storage plant Wendefurth did not permit earlier impounding.
Data
The curved gravity dam that impounds by their own weight Bode, is about 230 m long and 3 m at its crown and at the base about 30 meters wide. About the valley floor is 33.8 m and 43.5 m above the foundation level high. The mural crown is at 355.63 m above sea level. NN. The building volume contains approximately 115,000 m³ of reinforced concrete. The wall consists of 16 segments, which are sealed to the water side by inlaid into the concrete, copper sheets. In addition, the joints are sealed with tar and hemp. At the spillway wall with a free crown overflow is provided, which is 55.2 m long. At the bottom 2 bottom outlets are installed, you can leave with 4.2 m diameter up to 75 cubic meters of water per second, whose ring piston valve.
The adjacent rocks are not particularly waterproof manganese slate. This does not raise the wall from the bottom fitting sole water pressure, the sole is relieved by about 40 bells with risers. The building up of water pressure is measured it at intervals. Based on a tunnel dead long-term behavior of mountain rock is studied. In addition, the walls of several inspection tours crossed for revision purposes.
Hydroelectric power station
Between 2007 and 2009, a Kaplan turbine ( double regulated turbine spiral ) was installed in the dam of the dam Wendefurth that generates since in the context of a small hydropower plant with an installed capacity of 837 kW of electricity. Add to that the generation of an associated pumped storage power plant Wendefurth.
Reservoir
Location
The reservoir Wendefurth located in the village Wendefurth mostly in the area of the town Thale; only be near the dam of the reservoir adjacent Rappbode befindlicher part and its western foothills in the direction of the influence of Bode belongs to the city of Upper am Brocken. It is located between the near national highway 81 ( Wendefurth - Hasselfelde ) in the southeast and the somewhat distant State Road 27 ( Blankenburg - Elbingerode ) in the northwest, where the country road 96 (about Wendefurth - Rübeland ) in the southwest and the L 94 ( Almsfeld - Hüttenrode ) in the Northeast running between two major roads. The jammed river is the Bode, a tributary of the Saale in the catchment area of the Elbe; also lead Rappbode that previously flows through the Rappbodestausee, and a few small streams in the reservoir. Lie downstream along the now dammed water Bode valley left side of the tree- forest reservoir of Schieferberg ( 456.2 m above sea level. NN ), the somewhat distant Cow Mountain ( 469.2 m above sea level. NN ) and the turning Further Berg ( 446.1 m above sea. NN ) and right sides of the nickel mountain ( 488.2 m above sea level. NN ), Kohlberg (about 495 m above sea level. NN ) and the cemetery hill ( 452.3 m above sea level. NN ).
Data
The lake is about 78 hectares (0.78 km ²) in size. It extends approximately in the east-west direction at about 3.5 km in length and is located near the dam about 200 m wide. He has about 8.54 million m³ storage space and 9.22 million m³ total storage space. Its water level is at 351.9 m above sea level. NN. The catchment area is 309.20 km ². The flood control space is in the cold season 5.67 million m³. The average inflow is 5.02 m³ / s and the design flood at 191.7 m³ / s
Tourism and hiking
The operator, the dam operating Saxony- Anhalt, is the dam Wendefurth also for inspection by visitors. In a subsequent machine park visitors can see worn-out components.
A properties under forest near the dam of the reservoir above view point (approx. 370 m above sea level, . ⊙ 51.74316666666710.919333333333 ) is included as number 62 with name Wendefurth Dam ( mountain side ) into the system of stamp locations of the Harz hiking pin.
