The river springs as Weeser Aa southeast of the Ankum Heights and east of Merzen in Lower Saxony.[2] After crossing the boundary between Lower Saxony and North Rhine-Westphalia, it changes it name into Halverder Aa[3] and near Halverde [ar; de] (a district of Hopsten) into Halverder-Schaler Aa.[4] Near Schale [ar; de] (a district of Hopsten), it changes its name again into Schaler Aa.[5] Finally, it discharges into the Große Aa south of Freren.[6]
