The 30-kilometre (19 mi) long section of the Aller from the mouth of the Oker to Celle is referred to as the Middle Aller (Mittelaller).
After passing Wienhausen, it is navigable as far as Celle.
Here, the river has so much water that there are barrages and the water power is extracted from the river using weirs.
