Egå Engsø is an artificial lake and wetland site located in the north of the town of Aarhus between Vejlby, Risskov and Lystrup. Engsø means 'meadow lake' and Egå means 'oak stream', referring to the stream that drains the lake into the Aarhus bay. The lake area is bordered by the Djursland motorway to the north and the Aarhus-Grenaa railway and the municipal heating pipes from Studstrup Power Station to the south and east. == Background == Egå Engsø was created by re-flooding meadows on land previously drained in the 1950s for agricultural use. By the 1990s the water quality and natural ecosystem in and around the Egå river into which the site drained had declined due to the effect of nitrate fertilizer (eutrophication) use, through intensive farming in the area. Aarhus Municipality, Aarhus County and the Danish Forest and Nature Agency resolved to construct the lake as part of Vandmiljøplan II (English: ''Action Plan for the Aquatic Environment II'') from 1998 to reduce this effect through bacterial denitrification .〔(【引用サイトリンク】 title=Implementation of the Nitrates directive in Denmark )〕 Another major reason for initiating the project, have been the need for a strengthened defence against increasing rainfalls. The lake was created alongside work on the new Djursland motorway, and completed in 2006. Aarhus municipality is single owner. 〔(【引用サイトリンク】 title=Egå Engsø - a water treatment plant with a recreational profile )〕 〔(Wetlands reduce flood risks in Aarhus ) Task Force on Climate Change Adaptation〕 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「Egå Engsø」の詳細全文を読む スポンサード リンク
