The Samina (or Saminabach ) is a white water river that has formed the Saminatal , the westernmost valley in the Rätikon and the side valley of the Walgau . The Samina valley with its side valleys takes up about a third of the area of Liechtenstein , but is hardly populated. The river is ten kilometers long, two kilometers in Liechtenstein and eight kilometers in Vorarlberg , Austria . With the source rivers Stägerbach (and its source rivers Valünerbach and Malbunerbach) and Valorschbach, the Samina is the second longest river in the Principality of Liechtenstein after the Alpine Rhine .

Source and history

The Samina arises at Ölersegg (border point between Triesenberg , an exclave of Schaan (Brandegg) and an exclave of Balzers ), where Stägerbach and Valorschbach flow together. It flows through the eastern part of Liechtenstein from south to north and changes to 873  m above sea level. M. the limit. In the local area of Frastanz it flows into the Ill .

use

The water is used intensively to generate electricity on the one hand, and to supply drinking water to the Liechtenstein communities on the other hand, and has quality classes I to II.

Liechtenstein

In connection with the conversion of the Samina power plant into a pumped storage power plant in 2011–2015 , the government of the Principality of Liechtenstein authorized the Liechtenstein power plants on March 2, 2011 in accordance with the Liechtenstein Water Protection Act, according to which, when water is withdrawn from rivers, residual water is channeled into the water all year round to fulfill its ecological functions is to be guaranteed, obliged to deliver certain amounts of water to the Samina from the 1st of January 2013 at the water catchments at Malbunbach, Valünabach and Saminabach .

According to this decision by the Liechtenstein government, the following amounts of water are to be delivered to the Samina:

  • at least 20 l / s for the water intake on the Malbunbach
  • at the Steg reservoir, at least 25 l / s all year round
  • at the Rieter pumping station, a seasonal residual water volume of 50–120 l / s

This measure serves the ecological improvement of the water system of the Samina, but is also partly regarded as insufficient.

Austria

On the lower course of the Samina, the E-Werke Frastanz generate electrical energy from the Samina’s hydropower in three power plants.

The water is popular with athletes as a rafting river.

In the middle part of the valley on the border between Liechtenstein and Austria there is the European protected area Spirkenwälder Saminatal .
