In 1907, the Prussian state decided to canalise the Aller from above its confluence with the Leine near Schwarmstedt downstream to Celle.
In the years 1908 to 1918, the river was regulated by four barrages with locks and thus made navigable for larger inland ships.
In particular, the Aller locks in Bannetze and Oldau enabled the transportation of crude oil from the oilfields of Wietze to Celle.
Likewise, grain was shipped to Celle for milling.
