The Green Schwarza (ancient: Piestinggraben ) is a small mountain stream in the Gutenstein Alps in the municipality of Rohr im Gebirge on the border between the industrial district and the Mostviertel in Lower Austria . Together with the Dürren Schwarza, it is one of the two source streams of the Schwarza .

Run and landscape

The Green Schwarza rises on the Tettenhengst  ( 958  m above sea level ), an inconspicuous mountain on the border of the district of Wr. Neustadt-Land to that of Lilienfeld , and its westernmost area. A small area of ​​the catchment area belongs to the municipality of St. Aegyd am Neuwalde to the west of the summit .

The stream initially runs eastwards, passes the Ochsattel below, then south-eastwards, with which it circles the Steinaberg  ( 950  m above sea level ) to the north. It also takes in a stream that comes from the foot of the Hegerberg near Naglreith not far from the Kalten Kuchl via Werasöd and the Werasöder meadows . The east is here the Größenberg -Stock (Large  1,102  m above sea level. A. ). These mountains belong to the Reisalpe – Hegerberg group of the Gutenstein Alps.

After four kilometers of running, the Green Schwarza merges with the Dürren Schwarza in the Tiefental to form the Schwarza. From this confluence on, the name Tiefentaler Bach is initially found for the Schwarza, with which the Schwarza only begins at Gschaiderwirt in the main valley, a name that does not fit well with the naming of the two source streams.

The valley is uninhabited and very remote and belongs to Rohr im Gebirge as an orographic exclave . Only a small road leads through the valley, the L 4056 , which in the Tiefental creates the connection to the remote locations of Trauch von Schwarzau , Neukirchen district and Hochreith von Rohr. It leads from Gschaiderwirt through the Tiefental, then up the Ochsattel. The B 21 , an important supraregional east-west connection , runs via Kalte Kuchl - Naglreith - Werasöd - Ochsattel . The direct access to Werasöd is only a forest road.

In official hydrography, the Green Schwarza has not been considered the source stream of the Schwarza for so long, originally it was called Piestinggraben , the Dürre Schwarza Finstergrundgraben , the Schwarza to Gschaiderwirt Trauchbach or Tiefentalerbach , and the sources of the Schwarza were at Gschaiderwirt, Rohr im Gebirge or even seen at the Rohrer Sattel . The name "Piestinggraben" is quite astonishing, as the Piesting goes eastwards from the Rohrersattel.
