Gaißa
The Gaißa is a river in Bavaria, southeastern Germany, tributary of the Danube. It flows through the Bavarian Forest from North to South, crosses Aicha vorm Wald and joins the Danube northwest of Passau. Thereby the river reaches a length of approximately 25 kilometres. Due to the nearby motorway much dirt was flushed into the water from time to time. Meanwhile its grade is B quality.
