The stretch of the river between the junction with the Oder–Havel Canal near Liebenwalde and the confluence with the Spree at Spandau is administered as part of the [[Havel–Oder–Wasserstraße]], which also includes the Oder-Havel Canal. This stretch of the river forms part of the main inland waterway route from Germany to Poland and carries significant commercial traffic. This stretch of the river is {{convert|40|km|mi}} long, and the river descends through two locks at {{ill|Lehnitz|de}} and Spandau.<ref name=bsiwg100>{{cite book | first = Barry | last = Sheffield | publisher = Imray Laurie Norie & Wilson | location = [[St Ives, Cambridgeshire|St Ives]] | title = Inland Waterways of Germany | year = 1995 | pages = 100–103 | isbn = 0-85288-283-1 }}</ref>

At [[Hennigsdorf]], {{convert|30|km|mi}} downstream of Liebenwalde, the [[Havel Canal]] joins the river on the west bank. This canal connects to [[Paretz]], on the Havel downstream, and was built in the 1950s to allow [[East German]] vessels to avoid the stretch of the river under the political control of [[West Berlin]]. Some {{convert|7|km|mi}} further downstream, the [[Berlin-Spandau Ship Canal]] joins the river on the east bank, providing a connection to central Berlin without passing through the lock at Spandau.<ref name=bsiwg100/>

A car ferry crosses the river between [[Hakenfelde]] and [[Konradshöhe]], in the Berlin boroughs of Spandau and [[Reinickendorf]] respectively.

The last {{convert|10|km|mi|0}} of this stretch of the river, from Hennigsdorf, passes through a series of interconnected lakes, including the large [[Tegeler See]]. The river enters Berlin {{convert|6|km|mi|0}} before Spandau, having formed the boundary for the previous {{convert|4|km|mi}}. During the [[partition of Germany]], this formed the border between East Germany and West Berlin, and border control points were established for vessels navigating the river.<ref name=bsiwg100/>
