Parts of the Oudegracht follow the original flow of the river Rhine, but there is some disagreement on what parts. The northern part is most likely an early canal (app. 1000) connecting the Rhine section to the river Vecht.
The Oudegracht's layout mirrors the original Rhine River course in certain sections, but there is some contention over which parts. The northern part is likely a primitive canal (approximately 1000) that links the Rhine section to the Vecht River.
