The Liechtenstein Inner Canal is a body of water that was artificially created between 1931 and 1943, an inland canal in the Principality of Liechtenstein .

The inland canal runs parallel to the Alpine Rhine and receives the water from twelve Alpine streams. In Ruggell ( 47.2642 °  N , 9.531 °  O ) the internal channel opens out into the Rhine . The inland canal has a length of 23 km and a catchment area of ​​115 square kilometers. The inland canal is used for flood protection and drainage of Liechtenstein. After completion, large areas along the Rhine could be used intensively and profitably. Industrial areas emerged along the Rhine. At the beginning of the 1990s the canal was renatured and now serves as a breeding area and a. for the kingfisher .

history

Considerations to create an inland canal had already existed since 1894. The Liechtenstein parliament dealt with the matter. Between 1898 and 1902 further proposals were made to the state parliament. Due to the enormous cost, none of these were realized. Construction did not begin until 1931 and the ash and eleven other streams were fed into the canal. As a result of massive gravel extraction from the bed of the Rhine in the 1940s, there was a height difference of five meters from the inland canal. The gravel extraction led to a massive lowering of the groundwater level . At the confluence of the inland canal into the Rhine, there was a 4.5 meter high drop into the Rhine. This meant that fish could no longer enter the channel. A fish ladder built in 1982 did nothing to change that. Since 1984 the Liechtenstein government has started several revitalization projects.
