The Godnasee is an 18- hectare natural lake in Kehrigk , a district of the small town of Storkow in the Oder-Spree district of Brandenburg . It is located north of Alt-Schadow on the southern edge of the Dahme-Heideseen nature park and borders the Spreewald biosphere reserve . As Godnasee one also is moat called, which the south of the lake subsequent Josinsky-Luch in the Krumme Spree drained.

The stratified , eutrophic still water has a maximum depth of 6.5 meters. In the 2000s, the lake belonged to one of the seven inland waters in the North German lowlands that were experimentally stocked with eels in the catchment area of ​​the Havel as part of the EU regulation on the replenishment of the European eel population in order to obtain scientific bases for the quantification of mortality and the To develop modeling of the population dynamics of the European eel. The lake is completely surrounded by forest and designated as a nudist bathing lake.

Geography and geology

Location and transport links

The Godnasee is on the extreme southeastern district of Storkower hamlet Kehrigk . Its southwest, southern and southeastern banks form the border between the districts of Oder-Spree and Dahme-Spreewald and between the districts of Kehrigks and Alt-Schadows , a district of the Märkische Heide municipality in the Dahme-Spreewald district through which the Spree flows . The boundary line also marks the divide between the natural park and conservation area Dahme-Heide lakes in the north and the biosphere reserve Spreewald in the south. The village of Kehrigk is located around 3.9 kilometers northwest. The village center of Alt-Schadow in the southwest is much closer to the lake, at around 1.5 kilometers. The distance to the core of the city of Storkow in the north is around 13 kilometers, the city of Beeskow to the east around 20 kilometers, the city of Lübben in the south around 22.5 kilometers and to the south-east Berlin city ​​limits around 37.5 kilometers (all data refer to Beeline ). State road 42 runs parallel to the west bank at a distance of 300 meters , which connects Alt Schadow with Limsdorf and from which state road 74 branches off to Kehrigk to the west . The Godna lake can only be reached on forest paths.

Glacial channel and natural space

Central and southern part of the Scharmützelsee-Glubigseen-Rinne in the Schmettauschen map series from 1767/87 with a still recognizable channel structure and the meanwhile silted up lake Glinnitz between the Tiefen See ( Grubensee ) and Godnasee

The Godnasee is part of the Scharmützelsee - Glubigseen -Rinne, which borders the Beeskower Platte to the west. The glacial channel consists of the following topographical objects from north to south : Petersdorfer See , Wierichwiesen ( Niedermoorwiesen ), Scharmützelsee, Kleiner Glubigsee , Großer Glubigsee , Glubig-Melang-Fließ (sometimes also referred to as Grubenmühlenfließ ), Springsee , Glubig-Melang-Fließ, Melangsee , Grubensee (also: Tiefer See ), Godnasee and Josinsky-Luch . If the meltwater of the channel originally flowed south towards the Baruther Urstromtal / Spreewald, the direction of flow has reversed from Grubensee post-glacial north to the Berlin Urstromtal. The adjacent section from the Schmettauschen map series from 1767/87 shows the Glinnitz lake between the Godnasee and the Tiefen See / Grubensee. The body of water, first mentioned in writing in 1729 as Glinnitz (from Lower Sorbian glina , “loam, earth, clay”) was recorded in 1773 as Glinitz-Luch , has now silted up and is only shown on today's maps as a swampy, nameless area.

The Josinsky-Luch to the south is designated as an FFH area in the coherent ecological , Europe-wide Natura 2000 network and as a nature reserve within the Spreewald biosphere reserve. The FFH profile of the Federal Agency for Nature Conservation characterizes the 172 hectare Luch-area as follows: " fen area with wetlands , sedge vineyards , fresh meadows and pastures." The Luch drained over a ditch that begins just beyond the southern shore of Godnasees and today no Has more connection to the lake, in the Krumme Spree in Alt-Schadow. The Beeskower Platte to the east is listed as no. 824 in the natural spatial main units of Germany in the main unit group no. 82 East Brandenburg Heath and Lake District . The flat, undulating plateau is predominantly a floor moraine from the Saale Ice Age , the surface shape of which was formed by renewed glaciation in the last Ice Age . Above the 43.4 m above sea level. The water surface of Lake Godna, located at NHN , rises over a short distance to around 60 meters and reaches around 800 meters east with the Blocks Mountains, 110 meters. To the west of the lake, the area merges into the natural spatial main unit No. 822 Dahme lake area .

Hydrology and limnology

Morphometry and Trophy

The lake, which faces north to south or slightly south-west and is not very structured, has a length of around 720 and a width of around 250 meters. Its circumference is 1.985 kilometers, the area 18.55 hectares. The maximum depth of the layered lake is 6.5 meters, the average depth 5.5 meters. The depth of visibility for the month of May is given as 1.6 meters. The total phosphorus content (TP) in the 1990s was 44  µg / l . The trophy of the water is classified as eutroph1 / eutroph2 . Analyzes of samples taken from the lake between 1994 and 2002 resulted in a mean / trophic grade of 2.367 based on the diatom index from the trophic indices DI-PROF, DI-BENT and DI-LIT.

Drain, godnasee (ditch)

The Godnasee has no above-ground tributaries, but is fed from the groundwater . The body of water is described as having no outflow. Although there is no visible connection to the ditch starting a few meters behind the south bank, which drains the Josinsky-Luch to the Krummen Spree, the state surveying and geographic base information Brandenburg labels this ditch in their map as Godnasee [ditch?] (Status 2015). The Lundesumweltamt Brandenburg also has the ditch in the river register under the name Godnasee ( water code 58271352; length 2.24 kilometers). This name could indicate that water from Lake Godna got into the immediately adjacent lynx and into the ditch. In the lake directory, the State Environment Agency assigns Godna Lake to the Krummen Spree.

Flora and fauna

plants

Quarry forest on the south bank

The Godnasee is surrounded by the Kehrigker Forest, Alt-Schadower Forest and the Limsdorfer Heide. The post-glacial heaths were characterized by mixed forests of oak , beech and pine until around the year 1200 . After the medieval slash and burn , overexploitation and deforestation , the forests were specifically reforested from the middle of the 18th century and largely populated with pine trees, which grow comparatively quickly on the dry, loamy-sandy soils. In the forests, which are still dominated by pines, oaks and beeches are only scattered occasionally. Above the northeastern shore there is a pronounced birch - grove . In the swampy area on the south bank, the communities of the quarry forest predominate. The banks are largely bordered by a reed belt.

Animals

Fishing waters and fish

The Godnasee is a fishing water and is used by professional fishing . The operator and issuer of the fishing permits is the Spreewaldfischerei Richter in Alt-Schadow. Boat fishing is not allowed. Besides eels (see next section), the main fish species are perch and carp such as tench and various other white fish species . The pike is at the top of the food chain . The aggressive predatory fish eats all kinds of fish and does not shy away from its own conspecifics . Frogs, birds and small mammals also belong to its range of prey .

Project lake eel stock

European eel ( Anguilla anguilla )

In 2007 the European Parliament passed a Council Regulation on measures to restore the European eel stock . The ordinance obliged the member states to take effective measures to ensure sufficient silver eel exodus. To implement this, a research project was carried out in Germany with the aim of developing scientific “bases for the quantification of mortality and the modeling of population dynamics of the European eel in inland waters of northern Germany using the example of the Havel ”. To this end, seven project lakes with no outflow were selected and stocked with farm eels, i.e. eels reared in aquaculture , including the Godna lake. The project was financed with funds from the FIFG , an instrument of the common fisheries policy and the structural policy of the EU , and from 2009 to 2011 by the Federal Agency for Agriculture and Food .

Stocking took place with glass eels (the young fish) and pre-stretched eels . In Lake Godna, the survival rate of glass eels in 2010 was 16% and that of extended eels with 11% in the middle of the comparison lakes. Unusual accumulations of parasitization with tapeworms ( Proteosephalus spec. ) Were observed in Lake Godna and Lake Bohnenländer . The final project report from 2012 came to the conclusion that the eel stock in northern German waters will remain an indispensable instrument for the conservation of eel stocks in the short to medium term.

Fire-bellied toad, country gift to NABU

Red-bellied toads ( Bombina bombina ) were discovered around the year 2000 in a former peat cut on the shore of the lake . For the species "strictly protected" according to the Federal Nature Conservation Act (BNatSchG), "specially protected areas" are to be designated according to Annex II of the Habitats Directive . After learning of the need for protection of the frogfish , the farmer and his sister, who owned the pond, donated a two-hectare area with the water to the Lübben Regional Association of the German Nature Conservation Union (NABU). “We wanted to help preserve this idyll and the habitat of the toad .” As a thank you, NABU set up a boulder on the site with the multiline inscription: “2 hectares donated to NABU. Siblings Will 2002. "

Recreational use, nudist swimming lake and 66 lakes hiking trail

View over the lake from the south bank to the north

The Godnasee is designated as a bathing lake for naturism . On the south bank there is a larger, shaded sand lounging area and around the lake other small, partly overgrown berths. There are no sanitary or utility facilities. The lake is an insider tip among nudists. In addition to the good water quality and the idyllic surroundings, it is emphasized that the lake can be circled without a cover on a path and that the audience consists almost exclusively of nudists.

Stage 12 leads on a wide path from Wendisch Rietz to Leibsch of the 66 lakes hiking trail around Berlin past the lake. The path marked with a blue circle on a white square comes from Grubensee / Tiefen See to the north, runs parallel to the west bank of Lake Godna for a while and bends to the west towards the Tschinka forestry house on Neuendorfer See on roughly the middle of the bank . Another hiking trail runs through the hilly area above the east bank.

First mentions and etymology

The first known written mention of the water comes from the year 1514 as Gloden See in the Beeskow estate register . Under the compilation of the village of Schaadow (today Alt-Schadow), to which the lake was assigned at that time, it says:

"Matz Richter, is a lehn guth, [...] has freye fischerey with buffers and fish traps on the Gloden lake. Item also has a frey weir itself. However, in the short term he does not have to park or drive [...]. "

- Inheritance register of the Beeskow rule, 1514, in: Codex diplomaticus Brandenburgensis , A 20, p. 480

In 1772 the lake is documented as Gloden-See and one year later under its current name as Die Godna See . Since then it has stayed with this name, either in the spelling Godna See , Godna-See or Godnasee . The onomastics in the Brandenburg name books trace the name back to the Old Sorbian basic form * Glod'n- to * glod = hunger, * glod'n = hungry ( Lower Sorbian : głodny = hungry). The researchers suspect fish poverty as a motive for the naming; the Slavic name corresponds to the German Hungersee .
