The Schwarza , in the middle and upper reaches of Schönau and Hasel and in the Haselbach headwaters , is a 30 km long right tributary of the Hasel and at the same time its main hydrological arm in the Schmalkalden-Meiningen district in southern Thuringia . The Schwarza by name is 6.7 km long and is created by the merging of the Schönau with the Lichtenau coming from the right , which is also one of the main branches of the fan of the Hasel .

course

Spring run

The Haselbach rises at an altitude of almost 800  m , west-southwest of Oberhof in the west of the 904  m high Schützenberg in the Thuringian Forest . The source of the water in the valley axis is just over 785 m above sea level, and after 200 m the Haselborn comes at 790 meters above sea level on the left flank of the valley.

The stream then flows through the Kanzlersgrund , which separates the 900  m high main ridge of the Thuringian Forest (with the Rennsteig ) in the north from the more southerly mountain range, which is more separated into individual mountains. The stream runs at the foot of the north and north-west slopes of the Burned Stone ( 897  m ), the north slope of the Ruppberg ( 866  m ) and the north-east slope of the Großer Hermannsberg ( 867  m ).

Upper course

Once you have reached Oberschönau and Unterschönau , the name Schönau is common, but the river is still mostly referred to as Hasel on maps . The stream changes its direction from west-southwest to south and leaves the (actual) Thuringian Forest.

Middle course

In Steinbach-Hallenberg the river reaches the red sandstone foothills of the Thuringian Forest. The Herges district and finally the core municipality of Viernau are flowed through. Below flows from the left (= east) the Häselbach , 6.4 km, with its tributary Landwehr or Bermbach even 7.0 km long, with a catchment area of ​​13.1 km².

Lower course

In Schwarza the Schönau (so far 22.5 km long with 76.3 km² catchment area) almost doubles its water volume. First the Christeser Wasser (8.5 km, 23.8 km²) flows to the north of the town from the right , then, 800 m south of the town center, the Lichtenau (20.7 km, 49.4 km²).

The river, now called Schwarza, flows a further 6.7 km to the south and unites in monastery Rohr with the hazel coming from the east .
