The Aue is a left, southwestern, tributary of the Oste in northern Lower Saxony, Germany. It is about long. Geography Before the construction of the the Aue was the natural outlet of the lake in the southwest part of the parish of Wingst on the southern edge of the collective municipality of Am Dobrock. The Balksee is, in turn, fed by several streams. The Aue today no longer has any direct link with the Balksee and rises on its northern edge. The Aue, as a former sea creek, has no natural gradient. The water level is artificially held below sea level by dyke sluices and a pumping station.
