Hagener Au
The Hagener Au is a stream, roughly long, in the district of Plön in the north German state of Schleswig-Holstein. It is an outlet of the Passader See. From the lake's southwestern bay the stream flows in a northerly direction and discharges between Laboe and Stein in the Baltic Sea.
Sections of the Hagener Au are very natural and surrounded by wetlands. In addition the stream is a habitat for the rare spined loach. The stream has been straightened near its mouth and the last runs through a pipe.
Together with the Passader See the Hagener Au is a protected Special Area of Conservation.
