NavigableFrom the transition of the Oste-Hamme Canal into the Kollbeck (this is also where the kilometre marking begins) to the confluence with the Lesum.[4] The main limiting factors are the locks and the nature conservation regulations.

The Hamme (in its upper reaches Giehler Bach) is a 48 km (30 mi) long river in Germany, Lower Saxony, north-east of Bremen. Its source is north of Osterholz-Scharmbeck. It flows through the moors north-east of Bremen called Teufelsmoor, and meets the river Wümme in Ritterhude. From this junction, the river is called Lesum. The Lesum flows into the river Weser in Bremen-Vegesack.

On the river Hamme there are many water-sport clubs, for example the Wassersportclub Hamme e.V. (watersports-club Hamme), the Ruder-Verein Osterholz-Scharmbeck von 1901 e.V. (Rowing Club Osterholz-Scharmbeck since 1901) and the Segel Club Hamme e.V. (Sailing Club Hamme).
