The Giegel Aa is a left tributary of the Große Aa and belongs to the river system of the Ems . The course of the Giegel Aa flows from the division of the Hopstener Aa south of Hopsten and flows into the Große Aa at Beesten. So it is a river without a source.
course
It was created in 1565 after the construction of the Flootwerk in Hopsten, which was supposed to regulate the water of the Hopstener Aa. After 1.8 km through the Hopsten farmers' association Börnebrinck, they leave North Rhine-Westphalia and move to Schapen in Lower Saxony . The brooks Waldwiesengraben, Bahnhofsgraben, Kohlbrandgraben and Schapengraben are included between Schapen and Beesten , before the Giegel Aa flows into the Große Aa after 11.8 km south of Beesten.
Flootwerk
The Flootwerk was located in Hopsten on the street of the same name until it was demolished on October 24, 1962. It was a weir system that divided the water between the Hopstener Aa and the Giegel Aa. Since the water that flowed over the weir down to the Giegel Aa bypassed the watermill on Rheiner Straße, the Giegel Aa was also called Möllenumflut (Mühlenumflut).
The Flootwerk was built in 1565 and marked on a map from 1616 as Hopster Mollen Omfloed . In 1747 the stone floot plant was rebuilt. After the Flootwerk was torn down in 1962, the Hopstener Heimatverein secured a stone with an inscription to build from the Flootwerk.
The course of the Giegel Aa was shortened by relocating the branch by several hundred meters to its current location. The old river bed was filled in and partially built on.
Others
The Giegel Aa has found its way into the coat of arms of the municipality of Schapen alongside the Moosbeeke. Both rivers together form the two silver wavy bars in the coat of arms.
