Geography
Veliko Blato is situated in the southern part of the Pančevački Rit marshland. The lake is generally heart-shaped and covers an area of 1.8 km2 (0.69 sq mi) or 2 km2 (0.77 sq mi) with the adjoining fish ponds. It is the largest body of water in the Pančevački Rit, though it is shallow, as the maximum depth is only 1.5 m (4 ft 11 in). The area of the entire protected zone which surrounds the lake, and includes four fish ponds to the north, is 3 km2 (1.2 sq mi). The lake is embedded in the depression between the reed covered wet floodplains. The lake has no inflows or outflows, though the entire northern part is encircled by the Sebeš canal and another canal closely engulfs the entire lake. Water is replenished from the Danube and through the underground springs.[1]
The name of the lake means "great mudflat" in Serbian.
Wildlife
Plants
In and around the lake there are 191 plant species, out of which 14 are protected. Since 1865, when Josif Pančić found the first specimen, 30 species of orchids have been registered on the territory of the City of Belgrade. Two of them can be found only in Veliko Blato. One is marsh helleborine (Epipactis palustris (L.) Cr.), with some 200 individual plants. It grows only up to 20 m (66 ft) from the canal which encircles the lake. It was discovered near the lake in 2012. The other, with only some 50 specimens, is Orchis palustris Jacq. It grows between the turfs of grass where the water has dug minute canals. It was spotted for the first time in Belgrade in 1896 on the Great War Island, but was never seen again there. It has been re-discovered in the Makiš area in 1955, but by 2001 it disappeared, too.[1][2][3]
Animals
One species of fish, European weatherfish, is protected. Other of the 15 species of fish include carp, northern pike, wels catfish, zander and silver carp, though they are introduced later. There are also 9 species of amphibians and 4 species of reptiles. The lake is suitable for newts, frogs, lizards, grass snakes and dice snakes.[1]
Veliko Blato is inhabited by 120 species of birds. There is a mixed colony of heron species which consists of little egrets, squacco herons, grey herons, night herons and purple herons. The colony was discovered only in June 2013 and is the only nesting heron colony on the urban territory of Belgrade, with several dozens of nesting couples. Other birds include Eurasian coot, great cormorant, pygmy cormorant, Caspian gull, black-headed gull, diving duck, common pochard, mallard, tufted duck. Largest European eagle, white-tailed eagle, nests in the other parts of Belgrade (Great War Island, Ada Huja), but feeds in the area. The lake is an internationally important area for the bird protection.[1][2]
Human interaction
"Mika Alas", carp-breeding fish pond was established in 1961, when the lake was populated with many fish species. Veliko Blato is used as a feedlot for the larger fish. Four basins (including two fry ponds ), north of the lake, are built as a part of the fish pond. The lake is used for the sports fishing and all the fish that has been caught, must be released back into the lake. Every year, after the fishing season is over, the smaller basins are being emptied.[1]
In the early 2010s, an illegal dumping created a landfill south of the lake, which hastened the procedure of placing the lake under protection. Veliko Blato is not suitable for swimming and bathing due to the large quantities of mud in it.[1]
Protection
Veliko Blato is a high valuable biotope, especially given its vicinity to the big city. It is part of an ecological area "Sava's mouth into the Danube" and due to its importance for the nesting, migration and wintering of the birds, it has been declared an Important Bird Area.[2] It has been officially protected by the city government in May 2017, in the status of the "protected habitat".[4]
