course

Its two source rivers are called, just like those of the not far away Ilz , Große Ohe ( GEWKZ : 176; right upper course) and Kleine Ohe (GEWKZ: 1764; left upper course) and should not be confused with those namesake. These unite at Aicha vorm Wald to form the Gaißa, which from there flows in a sinuous south-easterly direction to the Danube. It flows east of Passau-Schalding and thus a few kilometers northwest of the central city of Passau . From the confluence of the river, the Gaißa is almost 20 km long, on the main strand from the source of the highest upper course of the Große Ohe it is 46 km. It drains a catchment area of ​​around 222 km².

The lower course of the water was at times heavily polluted by the nearby motorway, meanwhile the water quality class has leveled off at II.
