The
Swabian Rezat is a 27-kilometre-long
river in southern
Germany (
Bavaria). It is the southern, right source river of the
Rednitz. It rises in the
Franconian Jura hills, near
Weißenburg in Bayern. It flows generally north through the towns Weißenburg in Bayern,
Ellingen and
Pleinfeld. Together with the
Franconian Rezat, it forms the Rednitz in
Georgensgmünd. In its upper course the Rezat is close to the continental water shed between Rhine and Danube. In the 8th century Charlemagne tried to built a canal between Rezat and Altmühl which were only 3 km away from each other. Its not clear if it was finished and used for a short period or not. Its remains can be seen as "
Fossa Carolina" or "Karlsgraben" near
Treuchtlingen.
