The Löcknitz is a right tributary of the Spree in the state of Brandenburg with a length of a good 33 km. The Löcknitz spring area lies in the Märkisch-Oderland district west of Müncheberg.
The Löcknitz rises with a small pond at the Bienenwerder forest house between Müncheberg and its district Hoppegarten. The upper course to the Maxsee is also called Hoppegartener Fließ. After flowing out of the Maxsee, the Stöbberbach flows from the right to 1.5 km, and half a kilometer further at Kienbaum is the Lichtenower Mühlenfließ, which previously flowed through four lakes, most recently Liebenberger See.
From Kienbaum to the Fangschleuse district of Grünheid, the Löcknitz flows freely meandering and has retained natural bank structures for more than 20 kilometers, especially in the Löcknitztal nature reserve.
At the catch lock, the Löcknitz merges with the tributary Neue Löcknitz. From here, the current course of the river consists of the Löcknitz Canal created between Werlsee and Flakensee at the beginning of the 20th century. The old river bed is only preserved in remains here. The Rüdersdorfer Mühlenfließ also flows into the Flakensee. The lowest part of the Löcknitz from Flakensee to the confluence with the Dämeritzsee Spree is also called Flakenfließ. The water from the Löcknitz reaches the North Sea via the Spree, Havel and Elbe.
