	The permission to withdraw up to 25 m³/second from the Lippe still today is limited to a remaining discharge in the Lippe of 10 m³/second. If the water level in the river falls below that flow rate the Lippe receives up to 4,5 m³/second out of the canal system for low water replenishment. For example in the 12 months period from November 2014 to October 2015 the Lippe discharged on 257 days water into the Datteln-Hamm Canal and on 102 days canal water was pumped into the Lippe.
