The Rheinsberg Lake Region ( German : Rheinsberger Seengebiet ) with its many great and small lakes, lies in the richly-varied, gently rolling, forested countryside between the villages of Rheinsberg , Menz and Fürstenberg/Havel in the north German state of Brandenburg . It lies just to the south of the Neustrelitz Little Lakes Region , but has no natural link to the waterbodies to the north. However, the Rheinsberg Lake Region is linked to the Neustrelitz lakes via the Wolfsbruch Canal and Lock, the Müritz-Havel Waterway and the Upper Havel Waterway . It drains southwards to the River Havel through the Rhin and is bounded by Ruppin Switzerland to the south. The overwhelming part of the region belongs to the Stechlin-Ruppiner Land Nature Park . The Stechlin Nature Reserve, created in 1938, is well known.
20-735: The best-known lake in the Rheinsberg Lake Region is Lake Stechlin ( Stechlinsee ). Other large lakes in the region are the: Braminsee , Nehmitzsee , Großer Prebelowsee , Rheinsberger See , Roofensee , Schwarzer See , Tietzowsee , Großer Wummsee , Großer Zechliner See and Zootzensee . 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 21 kilometres (13 mi), were made navigable and connected to
40-532: A LIFE project was undertaken for the restoration of clear water lakes, mires and swamp forests of the Lake Stechlin. On 22 March 2012 The Global Nature Fund announced Lake Stechlin as the "Living Lake of the Year 2012". This Brandenburg location article is a stub . You can help Misplaced Pages by expanding it . Kettle bog A kettle (also known as a kettle hole , kettlehole , or pothole )
60-447: A dimpled appearance on the outwash plain. Lakes often fill these kettles; these are called kettle hole lakes. Another source is the sudden drainage of an ice-dammed lake and when the block melts, the hole it leaves behind is a kettle. As the ice melts, ramparts can form around the edge of the kettle hole. The lakes that fill these holes are seldom more than 10 m (33 ft) deep and eventually fill with sediment. In acidic conditions,
80-431: A kettle bog may form but in alkaline conditions, it will be kettle peatland . Kettles are fluvioglacial landforms occurring as the result of blocks of ice calving from the front of a receding glacier and becoming partially to wholly buried by glacial outwash. Glacial outwash is generated when streams of meltwater flow away from the glacier and deposit sediment to form broad outwash plains called sandurs . When
100-418: Is a depression or hole in an outwash plain formed by retreating glaciers or draining floodwaters . The kettles are formed as a result of blocks of dead ice left behind by retreating glaciers, which become surrounded by sediment deposited by meltwater streams as there is increased friction. The ice becomes buried in the sediment and when the ice melts, a depression is left called a kettle hole, creating
120-410: Is less than ten meters. In most cases, kettle holes eventually fill with water, sediment, or vegetation. If the kettle is fed by surface or underground rivers or streams, it becomes a kettle lake . If the kettle receives its water from precipitation , the groundwater table, or a combination of the two, it is termed a kettle pond or kettle wetland , if vegetated. Kettle ponds that are not affected by
140-858: 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 900-metre (3,000 ft) long Hütten Canal (also called the Jagow Canal), the Schlabornsee and the 1.5 kilometre long Schlaborn Canal, the Große Rheinsberger See and the 800-metre (2,600 ft) long Rheinsberg Canal as well as
160-558: 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 1.5-kilometre (0.93 mi) 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
180-739: 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 3 kilometres (2 mi) long, begins with the Wolfsbruch Lock (known in GDR days as
200-748: The Tietzowsee towards the west with the short Zootzen Canal, the Zootzensee lake, the 1.8-kilometre (1.1 mi) long Repent Canal, the Großer Zechliner See, the short Zechlin Canal and the Schwarzer See (also Kleiner Zechliner See) to its southwestern end after 8.49 kilometres (5.28 mi). The Rheinsberg and Zechlin Waters were Prussian waterbodies; only from 1921 to 1924 were they Reich Waterways. From 1990 they are Federal Waterways ( Bundeswasserstraßen ) and have belonged since 1998 to
220-468: The climate. The forests in this region are very varied. Its natural vegetation would be beech and beech- sessile oak woods. Today however it is dominated by Scots Pine and mixed pine woods. In smaller depressions and hollows today there are kettle bogs . The region became well-known through its coverage in the book Wanderungen durch die Mark Brandenburg ("Walks through the March of Brandenburg") by

At an elevation of 60 m, its surface area is 4.52 km . The Stechlin cisco , a dwarfed fish, is found only in this lake. Theodor Fontane 's last novel, Der Stechlin ,
260-595: The groundwater table will usually become dry during the warm summer months, in which case they are deemed ephemeral . If water in a kettle becomes acidic due to decomposing organic plant matter, it becomes a kettle bog ; or, if underlying soils are lime -based and neutralize the acidic conditions somewhat, it becomes a kettle peatland . Kettle bogs are closed ecosystems because they have no water source other than precipitation. Acidic kettle bogs and fresh water kettles are important ecological niches for some symbiotic species of flora and fauna. The Kettle Moraine ,
280-499: The ice blocks melt, kettle holes are left in the sandur. When the development of numerous kettle holes disrupt sandur surfaces, a jumbled array of ridges and mounds form, resembling kame and kettle topography. Kettle holes can also occur in ridge shaped deposits of loose rock fragments called till . Kettle holes can form as the result of floods caused by the sudden drainage of an ice-dammed lake. These floods, called jökulhlaups , often rapidly deposit large quantities of sediment onto
300-547: The melted ice block and on how deeply the block was buried by sediment. Most kettle holes are less than two kilometres in diameter, although some in the U.S. Midwest exceed ten kilometres. Puslinch Lake in Ontario, Canada, is the largest kettle lake in Canada spanning 160 hectares (400 acres). Fish Lake in the north-central Cascade Mountains of the U.S. state of Washington is 200 hectares (490 acres). The depth of most kettles
320-433: The region differs from the surrounding area due to its relief and its many lakes. There are many pockets of cold air ( Kaltluftinseln ). The cold air collects in hollows and is generally colder than that of the surrounding area. There are frequent early and late frosts. The average precipitation is relatively high at 563 millimetres (22.2 in) (Rheinsberg). A high humidity and low average summer temperatures characterise
340-427: The sandur surface. The kettle holes are formed by the melting blocks of sediment-rich ice that were transported and consequently buried by the jökulhlaups. It was found in field observations and laboratory simulations done by Maizels in 1992 that ramparts form around the edge of kettle holes generated by jökulhlaups. The development of distinct types of ramparts depends on the concentration of rock fragments contained in
360-737: The so-called special inland waterways of the Federation. The Eberswalde Water and Shipping Authority ( Wasser- und Schifffahrtsamt Eberswalde ) is responsible for them. The Rheinsberg Lake Region belongs, in terms of its historical formation, to the Mecklenburg Lake District . The region lies between the moraines of the Frankfurt Series and the Pomeranian Stage of the Weichselian glaciation and
380-505: Was formed during that ice age about 12,000 years ago in the meltwater valleys and sandurs of the Pomeranian. It has relatively high levels of relief for Brandenburg . There are flat sandur areas, undulating ground moraines and elongated end moraines . In between them lie the tunnel valley lakes and kettle lakes . These lakes do not generally have natural surface head and tailwaters. They were later linked by canals. Climatically
400-561: Was set in its vicinity. Stechlinsee has a maximum depth of 69.5 metres, making it the deepest lake in the State of Brandenburg. It is also one of the clearest with a visual depth of up to 11 metres (average 6 metres). The water is of drinking quality. It is home to the Leibniz Institute of Freshwater Ecology and Inland Fisheries . The Stechlin district is still one of the most important oligotrophic landscapes of Central Europe and
