Hase
The Hase is a river of Lower Saxony, Germany. It is a right tributary of the Ems, but part of its flow goes to the Else, that is part of the Weser basin. Its source is in the Teutoburg Forest, south-east of Osnabrück, on the north slope of the Hankenüll hill.
Weser-Ems watershed
After about, near Gesmold and about west of Melle, the Hase encounters an anomaly of terrain and bifurcates such that each branch flows into a different drainage system:- One third of its water flows along the south side of the Wiehengebirge hills eastward from Gesmold into the Else, which begins there, and flows into the Werre at Kirchlengern. The Werre is a tributary of the Weser.
- Two thirds of its water flows northwest from Gesmold toward Osnabrück, past the towns listed below, and toward Meppen, where the Ems receives its flow.
