According to its function, the old Danube in Straubing is the approximately two and a half kilometers long Straubing lock canal of the federal waterway Danube . This canal used to be an oxbow river of the Danube.
location
The Old Danube in Straubing is located in the Gäuboden in the area of the independent city of Straubing . It runs from west to east and is now over three kilometers long. Neighboring residents are the Hornstorf district in the north and the village of Gstütt on the inner island of the same name. The Agnes-Bernauer-Brücke crosses the canal.
Emergence
The Old Danube was originally created around 1480 by diverting the Danube into its current river bed, which runs further south. An artificial dam, the Sossauer Bschlacht , over 300 meters long , led the water into its new river bed dug by humans. The diversion turned the previously continuous section of the Danube into an artificially created oxbow lake , which only flowed through during high water when it flooded the dam. The aim of the relocation was that in future shipping should take the route directly past the city.
Sossauer Bschlacht
The dam near Sossau that closes off the oxbow lake was named differently, as the Sossauer Beschlächt , as the Sossauer Bschlacht or as Beschlacht . The basic word describes the hydraulic structure battle .
The dam ran from the tip of the inland island of Gstütt at the Wundermühle to the left bank of the Danube, west of today's mouth of the Kößnach . Size and construction were described around 1838 as follows: 328 meters long, between 12 and 15 meters wide. About nine rows of stakes 0.8 to 1.4 meters apart were filled with stones in the spaces between them. The stones weighed up to 2 tons. The length of the piles was between 12 and 16 meters. The posts were connected to one another with iron fittings. The top of the dam towered over the low water level by about 1.7 meters and was arched at the top. There was a level pavement between pegged cross connections that formed square fields.
Canal construction in the 20th century
When the Danube was expanded in the 1980s, the Old Danube was expanded as a canal and the federal waterway was moved into it. The Sossauer Bschlacht was dismantled in 1984 and a new separating dam was built up to the new Straubing barrage . Here the water of the Danube is now directed through the Straubing run-of-river power plant into the southern branch of the Danube, the branch of water to the right of the Trenndamm. Inland shipping uses the Old Danube , as the lower head of the Straubing lock is connected to the arm of the water to the left of the Tremmdamm.
After about two and a half kilometers, the Old Danube reunites with the Danube at river kilometer 2319.31.
