The canal is 47.2 kilometres (29.3 mi) long and has two locks, at Hamm and Werries, with a total rise of 6.8 metres (22 ft). In Hamm a water exchange facility of the Wasserverband Westdeutsche Kanäle is located that feeds the waterway with water out of the river Lippe to compensate evaporation, infiltration and operation of locks.
