Mills, drift wood and paper industries The hydropower of the Queich has been used to drive
mills for a very long time. From the 13th century onwards, the Queich was also used for
timber rafting. Timber rafting peaked in the middle of the 19th century. However, timber rafting required an adequate water flow;
splash dams were constructed to ensure this. However, while a splash dam is operational, the mills below it lack the water the need to run. When the timber rafting had completed, the splash dams would be torn down. Water was then abundant, but this often resulted in flooding the mill canals, and sometimes the mill canals were damaged by stuck logs. In 1881 finally managed to make the timber rafting stop altogether. Since 1881, the water is only used to drive the mills, except for one
paper mill in Sarnstall, who use the water for their manufacturing process, and release the polluted water back into the river.
Albersweiler Canal and fortress of Landau The city of Landau was expanded to a fortress by
Marshal Vauban in 1688–91, during the
War of the Palatine Succession. As part of this project, the was dug, a long navigable canal, connecting Landau to the
quarry at Albersweiler. The canal ran parallel to the Queich and was fed with water from the Queich. The canal was abandoned in 1874. However, many traces of this oldest artificial waterway in Germany remain, for example the
locks, with which the river water was diverted into the canal.
Queich Line During the
War of the Austrian Succession in the 1740s, the French forces constructed the
Queich Line, a line of fortifications between Landau and
Hördt on the left bank of the Rhine. Even today, some earthworks can be found in the Hördt Forest along the Spiegelbach.
Shift of the lower reaches Recent research results suggest that the lower reaches of the Queich near
Zeiskam were shifted to the north by about at some time in the past, perhaps already in the
Middle Ages. The reason may have been that timber rafters needed to shift the confluence with the Rhine into the town of Germersheim. == Transport ==
