Ammersee (English: Lake Ammer) is a Zungenbecken lake in Upper Bavaria, Germany, southwest of Munich between the towns of Herrsching and Dießen am Ammersee. With a surface area of approximately , it is the sixth largest lake in Germany. The lake is at an elevation of , and has a maximum depth of . Like other Bavarian lakes, Ammersee developed as a result of the ice age glaciers melting. Ammersee is fed by the River Ammer, which flows as the Amper out of the lake. Like neighbouring Lake Starnberg, which is similar in size and shape, it is a popular location for watersports. Ammersee and the Amper are part of the ancient Celtic amber trading route leading to the Brenner Pass. The word ''Ammer'' is a 13th-century form of ''Amper'', the Celtic '' *ambra'', deriving from the Indo-European '' *ombh-, *mbh-'' "wet, Water".〔Dieter Berger: ''Duden - Geographische Namen in Deutschland.'' 2nd ed., Dudenverlag, 1999, ISBN 978-3-411-06252-2.〕 Passenger services have operated on the lake since 1879. Today they are operated by the Bayerische Seenschifffahrt company, using a mixture of historic paddle steamers and motor ships. ==Ecology== The lake's water generally is of very good quality since a circular sewerage system has been introduced in the 1960s collecting all wastewater from around the lake and transporting it to a treatment plant below the lake's outlet at Eching. The Ammersee abound on fish and is the home of the vulnerable species of deepwater char ''Salvelinus evasus''.〔(Revue Suisse de Zoologie - Salvelinus evasus )〕 Deepwater char are highly sensitive to changes in the quality of the water and some species such as ''Salvelinus neocomensis'' and ''Salvelinus profundus'' were driven recently to extinction in other European lakes.〔(Red List - Volume 1: Vertebrates (2009) - General assessment for the vertebrate groups )〕 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「Ammersee」の詳細全文を読む スポンサード リンク
