The Kristeinbach is a brook in the communities of Anras and Assling ( Lienz district ). The brook has its source in the Villgraten Mountains and flows into the Drau at Mittewald .
history
The Kristeinbach was already in a document from Duke Tassilo III. Mentioned from 769 in favor of the establishment of San Candido Abbey as "rivolum montis Anarasi" (literally "Bach des Anraser Berg") and for centuries it formed the fluctuating eastern border of the San Candido monastery area.
course
The Kristeinbach rises on the southwest slope of the connecting ridge between the mountains Beim Kreuz and Hochegg in the Villgraten mountains. It then flows in an arc to the southeast and then in a southeast direction through the Kristeiner Tal. On its way it passes the districts of Vergein , St. Justina and Mittewald of the municipality of Assling in the lower reaches and flows into the Drau on the left at Mittewald. Almost the entire course of the stream forms the border between the communities of Assling and Anras.
Energy use
There are two power plants on the Kristeinbach. The larger of the two power plants was built by the municipality in 1973. It is a diversion power plant with an output of 2,550 kW. The penstock is 4980 meters long and overcomes a height difference of 540 meters. In 1980 the power plant was supplemented by a daytime peak storage facility in the form of a round silo with a diameter of 18 m and a height of 10 m. Due to the capacity of around 2000 m², larger daily peaks can be compensated. As early as 1980 and between 2000 and 2003, the pressure pipeline had to be renovated or replaced. The average annual production is 16.5 million kWh.
A second, private power plant originally only served to cover the electricity needs of the farmer Erwin Lukasser. When he expanded his operations in 1989, the power plant was also rebuilt. With the support of the State of Tyrol, the power plant was revitalized in 2014 and a fish pass was built. The power plant has an annual production of around 2 million kWh.
