Kalflack

The Kalflack is a tributary that winds about 35 kilometers through the Wesel and Kleve region, connecting several towns and villages. The water collects from a large drainage area before flowing into the Rhine.

The Kalflack is a former branch of the Rhine, maintaining its original path for centuries. It formed when the river once split into multiple channels across this landscape.

The Kalflack provides living space for birds that are rare elsewhere in the region. You can spot kingfishers hunting along the banks and see swans arrive in winter to stay for several months.

At the Hürdendeich dam you will find a fish ladder where fish can move between this river and the Rhine. The best time for observation is during the warmer months when fish are most active.

This river flows through ten distinct former waterways in the Lower Rhine region, each with its own vegetation of floating plants and reed zones. This network of old channels creates a complex mosaic of different habitats.
