[1] North of Prieros the Dahme flows through a number of lakes, including the Dolgenzee, Krüpelsee and Krimnicksee before reaching the city of Königs Wusterhausen.

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.

[1][2] The Dahme is navigable as far upstream as Märkisch Buchholz, although the reach above Prieros is shallow and generally only used by leisure craft.

Canoes and similar craft can by-pass a weir near Märkisch Buchholz and enter the Dahme Flood Relief Canal which is then navigable to its junction with the upper Spree.

The Gosen Canal also links the Sedinsee with the Spree, and thus provides a shorter route to the Müggelsee, Woltersdorf and Rüdersdorf for traffic coming downstream.
