Ecker Dam

Found decommissioned, Found developer, Found licence_expires,

The Ecker Dam (German: Eckertalsperre) is a dam near Bad Harzburg in the Harz mountains of Germany that went into service in 1942. It impounds primarily the waters of the river Ecker.

Operation

The dam is operated by the Harzwasserwerke. It is used for the supply of drinking water, flood protection, raising water levels during times of low rainfall and electricity generation through hydropower. Its power generation capacity is 270 kW. The Ecker Dam has an average discharge of 16 million m³ per year.

Construction

The facility comprises a gravity dam made of concrete. For the first time in Germany coarse-grained concrete (Rüttelgrobbeton) with an aggregate of up to 300 mm grain size was used. The reservoir uses a section of the valley which, below a prominent trough end, was dug out in the shape of a basin by an ice age glacier.

Purpose

The reservoir provides drinking water to the cities of Brunswick and Wolfsburg.

History

Dam

A dam is a barrier that impounds water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for such activities as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions.

The word dam can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities.

History

Ancient dams

Early dam building took place in Mesopotamia and the Middle East. Dams were used to control the water level, for Mesopotamia's weather affected the Tigris and Euphrates rivers, and could be quite unpredictable.

The earliest known dam is the Jawa Dam in Jordan, 100 kilometres (62 mi) northeast of the capital Amman. This gravity dam featured an originally 9-metre-high (30 ft) and 1 m-wide (3.3 ft) stone wall, supported by a 50 m-wide (160 ft) earth rampart. The structure is dated to 3000 BC.
