The Waldnaab is the left or eastern source river of the Naab in the Upper Palatinate ( Bavaria , Germany ). It is in turn formed by the union of two source rivers, the longer Tirschenreuther Waldnaab from the Upper Palatinate Forest and the more water-rich Fichtelnaab from the Fichtelgebirge . With the Tirschenreuther Waldnaab, it is 99 km long and thus the longer of the Naab source rivers. The Naab reaches a total length of 197 km via this flow path.
Surname
The Waldnaab got its name to distinguish it from the other Naab spring rivers . It is derived from the former large forest areas of the Upper Palatinate Forest.
Course and valley landscape
The hydrological data of the two source rivers of the Waldnaab differ only slightly. With an average discharge of 3.7 m³ / s at the mouth, the Fichtelnaab is a little larger than the longer Tirschenreuther Waldnaab.

Tirschenreuther Waldnaab
The left, eastern source river rises at 816 m above sea level. NN on the German- Czech border in the Upper Palatinate Forest near the 901 m high Entenbühl or its smaller brother, the Naabberg ( 853 m above sea level ). The source , also known as the “Kreuzbrunnen”, is in the Tirschenreuth district , near Silberhütte . The water flows from the spring catchment only three meters on German soil before it touches western Bohemia for two kilometers as Lesní Nába and, flowing to the northwest, crosses the German border again and reaches Bärnau .
Due to the weather, the water often only emerges a few meters below the disintegrating source, on the Czech side. During the Cold War , the spring at the then strictly guarded border was heavily frequented by walkers or to pick blueberries between the border posts , often under the eyes of border guards on both sides.
After it has left the forest, it is the first village on its course to flow through the Naab of the same name . In Bärnau the Waldnaab bends to the west and flows through the approximately 88 hectare large flood reservoir Liebenstein a little below Bärnau-Thanhausen or north of Plößberg . Then it turns north and reaches Tirschenreuth , where it bends back to the west and flows in numerous meanders through the lake-rich Waldnaabaue.
Past the castle Falkenberg in Falkenberg it reaches now to the southwest flowing, the approximately 12-kilometer-long wooded Waldnaabtal with many granite rock formations on or in the river, such as the Chamber of cars , the table stone or churn , and the former castle places Altneuhaus , Herrnstein and Black surge . To the south of Falkenberg, a section about 6 kilometers long is designated as the Waldnaabtal nature reserve.
Fichtelnaab
The source of Fichtelnaab is located on the southeast slope of the Ochsenkopf ( 1024 m above sea level. NN ) about 800 meters southeast of the source of the White Main and about two kilometers northwest of Fichtelberg or the 10.5 hectares large Ficht Kochel (752 m above sea level. NN). From then on it flows in a broad Muldental generally south-eastwards via the villages of Fichtelberg and Mehlmeisel into the Tirschenreuth district . There the Fichtelnaab arrives via Brand , Ebnath , Neusorg and Erbendorf to Windischeschenbach , where it merges with the Tirschenreuther Waldnaab.
Waldnaab below the confluence
Below the confluence of the Fichtelnaab and Tirschenreuther Waldnaab near Neuhaus near Windischeschenbach , the Waldnaab flows southwards through a wide meadow valley, not far from the A 93 and the B 15 , via Neustadt and Altenstadt to Weiden , where it takes in the Schweinnaab from the west . At Unterwildenau it joins the Haidenaab to form the Naab , which flows into the Danube at Regensburg - Mariaort .
