In 1876-1881 the chains of lakes within the Rheinsberg Lake Region known as the Rheinsberg and Zechlin Waters (
Rheinsberger Gewässer and
Zechliner Gewässer), stretching for about , were made navigable and connected to the Müritz-Havel Waterway via the Wolfsbruch Lock. The Rheinsberg Waters branch into the lake of Kleiner Pälitzsee from the Müritz-Havel Waterway. At the Pälitz Bridge – the former border between Mecklenburg-Strelitz and Prussia, the present border between the states of Mecklenburg-Vorpommern and Brandenburg – a lock canal, not quite long, begins with the
Wolfsbruch Lock (known in GDR days as the
Hütten Canal, but from 1998 as the Wolfsbruch Canal (
Wolfsbrucher Kanal).) After that com the Großer Prebelowsee lake, the short Prebelow Canal, the Tietzowsee lake, the long Hütten Canal (also called the Jagow Canal), the Schlabornsee and the 1.5 kilometre long Schlaborn Canal, the Große Rheinsberger See and the long Rheinsberg Canal as well as the Grienericksee before reaching its southern end at kilometre marker 13.25. The Rheinsberg Waters also include the 3 kilometre long Dollgow Canal and Dollgowsee that branch off the Schlabornsee towards the southwest. Until 1990 the long Bikow Canal and Bikowsee that branched off the Schlabornsee towards the east were also counted as part of the Rheinsberg Waters. The Zechlin Waters lead from the Tietzowsee towards the west with the short Zootzen Canal, the Zootzensee lake, the long Repent Canal, the Großer Zechliner See, the short Zechlin Canal and the Schwarzer See (also Kleiner Zechliner See) to its southwestern end after . The Eberswalde Water and Shipping Authority (
Wasser- und Schifffahrtsamt Eberswalde) is responsible for them. == Geology ==
