Aare scale
The Aare scale (in the local Swiss German dialect Woog ) is a vortex phenomenon in the Swiss river Aare near Aarburg , Canton Aargau . In 1996 it was included in the federal inventory of landscapes and natural monuments of national importance .
At the location of the Aare scales, the river widens into a wide natural harbor basin on the one hand and meets the rock on which the Aarburg fortress stands on the other . The large eddy, the “scales”, is created by the fact that the main current of the Aare flows past the calmer water in the basin and its water level increases cyclically, reinforced by the deflection of part of the current through the fortress rock and the tributaries of the streams Tych and Dorfbach .
The Aarewaage was endangered several times by planned construction work in its existence or in its appearance. If the Ruppoldingen power plant had not been expanded in the 1950s, the port basin would have been destroyed. In the 1970s a railway bridge was to be built at the Aarewaage, but landscape protection considerations prevailed and the railway was instead led through the Born tunnel .
In December 2013, part of the landmarked river bank in the area of the Aare weigher collapsed. The renovation took place from April to May 2014.
