Koppenwinkel lacquer that fell dry in December 2013

The Koppenwinkellacke is a karst body of water in the Koppenwinkel near the Koppenrast in the municipality of Obertraun in the Upper Austrian Salzkammergut .

The lake, actually a lacquer (pond) , located in the middle of alluvial forest , is about 200 meters long and divided by bays, as well as one larger and several smaller islands. The water depth is a maximum of half a meter. The water supply is exclusively underground. The water comes from the 840 km² Dachstein plateau , where it seeps through ponors and is only pushed into the lake by the impermeable rock layer through the gravel layer. If there are meter-high snow covers on the Dachstein massif in winter, the lake can dry out due to the lack of water supply. The lake last fell completely dry in autumn 2009. The overflow drains over the small Koppenwinklbach to the nearby Koppentraun .

The Koppenwinkellacke is about a 10 to 15 minute walk from the Obertraun-Koppenbrüllerhöhle train station and can be easily reached on foot or by bike.

The body of water, like the entire Koppenwinkel, has been under nature protection since 1978 and European protection since 2005 ( Dachstein nature reserve in the municipalities of Gosau, Hallstatt and Obertraun ,  N098 ; Dachstein European protection area ( FFH / BSG ,  AT3101000 / EU02 )) and has been part of the Core zone of the UNESCO World Heritage Site of the Hallstatt – Dachstein / Salzkammergut cultural landscape ( WHS 806 ).
