Lake Skadar
Lake in Albania and Montenegro From Wikipedia, the free encyclopedia
Lake Skadar (Albanian: Liqeni i Shkodrës, pronounced [liˈcɛni i ˈʃkɔdrəs]; Montenegrin: Скадарско језеро, Skadarsko jezero, pronounced [skâdarskɔː jɛ̂zɛrɔ]) – also called Lake Scutari, Lake Shkodër and Lake Shkodra – lies on the border of Albania and Montenegro, and is the largest lake in Southern Europe. It is named after the Albanian city of Shkodër which lies at its southeastern coast. It is a karst lake.

The Montenegrin section of the lake and surrounding land have been designated as a national park, while the Albanian part constitutes a nature reserve and a Ramsar site.
Lake Skadar is the largest lake in the Balkan Peninsula with a surface area that seasonally fluctuates between 370 km2 (140 sq mi) and 530 km2 (200 sq mi).[1] Lake Skadar itself is located in the western Balkan region.
The lake is located in the border area between Montenegro and Albania, the Montenegrin share of the area of the lake is larger than the Albanian one. The lake's water level also varies seasonally from 4.7 to 9.8 metres (15 to 32 ft) above sea level. The lake extends northwest to southeast, and it is approximately 44 km (27 miles) long.[1]
The Buna River connects the lake with the Adriatic Sea, and the Drin River provides a link with Lake Ohrid.[1] The lake is a cryptodepression, filled by the river Morača and drained into the Adriatic by the 41 km (25 mi) long Buna (Serbo-Croatian: Bojana), which forms the international border on the lower half of its length. The largest inflow is from the Morača, which provides about 62% of the lake's water.[1] Total drainage area is 5,490 km2 (2,120 sq mi).[1]

There are additionally some fresh water sources at the lake bottom. A characteristic feature of Lake Skadar's water balance is the high inflow from a number of temporary and permanent karst springs, some of which are sublacustrine in cryptodepressions (known as an oko).[1] The southern and southwestern sides of the lake are rocky, barren and steep, having bays in which the sublacustrine springs are usually to be found.[1] On the northern side there is an enormous inundated area, the boundaries of which change as water levels fluctuate.[1]
Some small islands like Beška, with two churches on it and Grmožur, a former fortress and prison can be found on the southwestern side of the lake.
The climate type is hot-summer Mediterranean climate with dry summers (Csa), under Köppen climate classification.[1]
The Montenegrin part of the lake and its surrounding area were declared a national park in 1983. The Albanian part has been designated as a Managed Nature Reserve. In 1996, by Ramsar Convention on Wetlands, it was included in the Ramsar list of wetlands of international importance.[4] Near the mouth of Rijeka Crnojevića, 11 m (36 ft) below the surface of the water there is a well-preserved wreck of the steamboat Skanderbeg sunk by partisans in 1942, during the Second World War.[5]

Lake Skadar is presumably an ancient lake, although it is a relatively young ancient lake.[1]
Most authors agree that the Lake Skadar basin is of tectonic origin which had been formed due to the complex folding and faulting within north eastern wing of Old Montenegro anticlinorium (High Karst Zone).[1] These movements took place during the Cenozoic period. The lake basin has been formed as the result of sinking of blocks in the Neogene period or even in Paleogene.[1] In the Miocene and the Pliocene marine conditions prevailed in the Zeta Plain, which was sunk at the beginning of the upper Miocene, and that the sea inundated this plain up to Podgorica during the Pliocene.[1] Radoman (1985)[6] pointed out that sea must have destroyed all the freshwater populations on this plane and in the Lake Skadar area.[1] The connection of Lake Skadar with the sea was interrupted during the younger Pliocene.[1] The question of the origin of its water is of particular interest for biologists as these waters may have provided its first species and been the basis for its present high degree of endemism.[1]
The Lake Skadar system is a well-known hotspot of freshwater biodiversity and harbors a highly diverse mollusc fauna.[1]
Lake Skadar is one of the largest bird reserves in Europe, having 270 bird species, among which are some of the last pelicans in Europe, and thus popular with birders. The lake also contains habitats of seagulls and herons. It has been recognised as an Important Bird Area (IBA) by BirdLife International.[7][8]
It is abundant in fish, especially in carp, bleak and eel. Of the 34 native fish species, 7 are endemic to Lake Skadar.[9]
At the scale of Lake Skadar, about 31% of freshwater snails (12 out of 39 species sampled in the lake) are endemic.[1] At the scale of the Lake Skadar basin, 38% (19 species) of the total freshwater gastropod fauna appear to be endemic.[1] There were reliably recorded 50 species of freshwater snails from the Lake Skadar basin.[1] The index of freshwater gastropod endemism is 0.478.[1] With this relatively high value, Lake Skadar exceeds such famous lakes as Lake Malawi and Lake Titicaca.[1] Lake Skadar is inhabited by five species of Bithynia and it is a hot spot of Bithynia evolution.[1]
There are 17 amphipod species for the Lake Skadar watershed, 10 of them being endemic (mainly from the subterranean habitat).[1]
The small range of many endemic species living in the Lake Skadar system together with ever increasing human pressure make its fauna particularly vulnerable.[1] This becomes even more important in light of ongoing eutrophication, water pollution and sand and gravel exploration activities in the lake and its basin.[1] Research of the phytoplankton community and chlorophyll-based trophic state indices show that the lake is on a betamesosaprobic level of saprobity, which means moderately polluted with organic compounds.[1] Effects of human-induced environmental changes are especially evident for sublacustrine springs, with eutrophication and use for water supply (e.g., sublacustrine spring Karuč) being the most serious threats.[1]
The 2011 IUCN Red List of Threatened Species includes 21 endemic species from the Lake Skadar basin.[1]
Radio Skadar, a radio station based in Podgorica, is named after Lake Skadar.
