Downstream of Königs Wusterhausen the river is linked to the Möllenzugsee on the right bank, and shortly thereafter by the linked Grosser Zug and Krossinsee on the same bank. The Dahme then flows into the Zeuthener See, which links to the Seddinsee and Langer See at the outer Berlin suburb of Schmöckwitz. The Dahme flows out of the Langer See at its north-western end, shortly before it confluence with the River Spree at Köpenick, a historic town that is now a suburb of Berlin.
