Welse is a river of Brandenburg, Germany. It flows into the Hohensaaten-Friedrichsthaler Wasserstraße, a shipping canal parallel to the Oder, north of Schwedt. It is 66 km long, and has its source 2 km northwest of the centre of Friedrichswalde about 73 m above sea level. After a flow path of 5.5 km, of which about 400 m are piped, the spring creek flows into the Großer Präßnicksee.[1]
