This artificial lake at the periphery of the city is a popular local recreation area and a favorite spot for aquatic sports.  

The Aa, Münster's local river, was dammed at this point creating an inland lake that has become a favorite place of recreation and a welcome opportunity for fans of water sports.

During the summer months, the boat "Professor Landois" cruises on the lake and stops at major attractions such as the All-Weather Zoo, the Westphalian Museum of Natural Sciences and the Mühlenhof Open-Air Museum.
