The Jeker ( French Geer , historically: Worm) is a 54 km long river in Belgium (50 km) and the Netherlands (4 km). It is a left and west tributary of the Meuse .
geography
course
The Jeker has its source in Lens-Saint-Servais in the municipality of Geer .
Although two of the three most famous places on the river, Tongeren and Maastricht, belong to the Dutch-speaking area, the greater part of the river, also between the two cities, is in French. The third city on the river, first in the direction of flow, is Waremme ( Dutch: Borgworm).
On the southern outskirts of the village of Kanne , the Jeker meets the Albert Canal . Since the river and the canal are roughly at the same height, the jeker is routed in a culvert through a system of communicating pipes under the wide canal and can then continue its way to Maastricht undisturbed.
The Jeker flows into the Meuse in Maastricht .
Catchment area
The 474 km² catchment area (Wallonia: 375 km² / Flanders: 90 km² / Netherlands: 9 km²) of the Jeker is drained into the North Sea via the Meuse and the two southern arms of the Rhine-Meuse Delta .
The slightly undulating catchment area belongs to the Hespengau and is characterized by arable land with small patches of forest interspersed. Grains, beets and vegetables are grown intensively in the arable land.
In the municipality of Bassenge ( Dutch Bitsingen) east of Tongeren, the Geer valley is cut a little deeper. There is a very small wine-growing area for white wine here.
Tributaries
The largest tributary of the Geer is the Yerne , which has its source in the municipality of Verlaine and flows into Oreye ( Dutch: Oerle).

Mills
With a height difference of 100 m in total, the river was used to operate numerous mills. In downtown Maastricht, paper mills from the 18th century have been preserved.
