Neue Luppe

Neue Luppe, also called the Luppe Canal, is an artificial tributary of the White Elster in Saxony and is legally classified as a first-order watercourse. Up to its mouth, it is the main arm of the Elster-Luppe river system and carries more water than the White Elster itself.
The Neue Luppe begins at the Elsterbecken. It is a left tributary of the White Elster River, which it joins near Schkeuditz.
