The Demer is a river in Belgium that flows through the province of Flemish Brabant and into the city of Leuven, ultimately joining the River Maas. It spans approximately 90 kilometers and is known for its pleasant natural surroundings, especially in rural areas. The water temperature in the Demer fluctuates throughout the year.

Swimming in the Demer is possible, but not always recommended, especially in urban areas. The water quality can be affected by various environmental factors such as agricultural runoff, urban development, and occasional pollution events. The river is mostly shallow in many areas, with water depths that can make swimming more challenging, especially after periods of heavy rainfall when the water levels may fluctuate.
