The Demer and its tributaries in the south of the province of Limburg

The most important towns along the Demer are (starting from the source) Bilzen, Hasselt, Diest and Aarschot. Tributaries of the Demer are the rivers Herk, Gete and Velp (all three in Halen).

The name "Demer" comes from the Celtic language words "tam" (dark coloured) and "ara" (water) giving rise to a name meaning "dark coloured river". The Winter brook (Beringen) is a tributary of the Demer River.
