In addition to water-carrying ditches and ponds, there are also long-abandoned ditches and dry pond beds. The Lower Harz Pond and Ditch System ((ドイツ語:Unterharzer Teich- und Grabensystem)), which forms the major part of these old water management facilities, lies in the central Lower Harz, almost entirely within the borough of the present-day town of Harzgerode. == Extent == In the central Lower Harz between the villages of Neudorf, Silberhütte, Straßberg, Großem Auerberg and the upper Lude river is the only, historical, mine water management system in the Lower Harz. Sheltered by the geographical-climatic conditions of the Lower Harz, the system never reached the scale of comparable systems in the Upper Harz and the Ore Mountains. The river catchment areas affected are primarily the source regions and upper reaches of small mountain streams. Parts of the water management system can be dated back as far as 1320. This network of ditches (''Kunstgraben''), trenches (''Rösche'') and ponds (''Kunstteiche'') has been called the Lower Harz Pond and Ditch System. There are about 300 ponds in the Lower Harz as a whole. Of these, 36 were mining ponds that had a combined retention capacity of 2.6 million m³.〔Wilfried Ließmann: ''Historischer Bergbau im Harz'', p. 324〕 The ponds of the Lower Harz Pond and Ditch System thus held about 40% of the capacity of all Lower Harz ponds. This amounts to some 26 ponds,〔The figures in the literature vary, so the figure may be higher if pre-dammed reservoirs are included.〕 most of which are covered today. They currently serve mainly as drinking water reservoirs. All elements of the mine water management system, regardless of condition, were placed under conservation orders in 1991 as a heritage area (''Flächendenkmal''). In doing so, the name of "Lower Harz Pond and Ditch System", which was already in use no later than 1986 for the system of the central Lower Harz, was broadened by the Saxony-Anhalt Department of Heritage Conservation and Archaeology (''Landesamt für Denkmalpflege und Archäologie Sachsen-Anhalt'') to cover the whole of the Harz Mountains lying in Anhalt, although this step was not followed by the literature that appeared later. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lower Harz Pond and Ditch System」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
