The adjective lomný denoted a frequently bending river, but also a stone suitable for quarrying. This could refer to the character of the river bed, which contained gold.[1]
Characteristic
Confluence of the Lomnice (left) and Otava
The Lomnice originates in the territory of Rožmitál pod Třemšínem in the Brdy Highlands at an elevation of 745 m (2,444 ft) and flows to Oslov, where it enters the Otava River at an elevation of 349 m (1,145 ft). It is 59.3 km (36.8 mi) long. Its drainage basin has an area of 830.7 km2 (320.7 sq mi).[2]
The drainage basin is rich in fishponds, especially in the area of the Blatná Uplands. There are 241 bodies of water in the basin area larger than 1 ha. The largest of them is the Labuť pond with an area of 101 ha (250 acres), built on the Kostratecký potok. Several fishponds are built directly on the Lomnice. The large Orlík Reservoir, built on the Vltava River, extends also into the river mouth of the Otava and Lomnice.[2]
Protection of nature
Vystrkov Nature Monument
The spring and the first kilometres of the Lomnice are located within the Brdy Protected Landscape Area. The river also flows through several small-scale protected areas.
The Hořejší rybník Nature Reserve protects the area of the fishpond Hořejší rybník and its surroundings, including the mouth of the Lomnice to the pond. The nature reserve has an area of 56.6 ha (140 acres). The object of protection is a pond ecosystem with very well-preserved littoral vegetation and adjacent mesophilic meadows and waterlogged alder forests, which has high biodiversity.[4] Near Hořejší rybník is located the fishpond Dolejší rybník whose bank is protected as the Dolejší rybník Nature Reserve with an area of 6.5 ha (16 acres). It is an important site of non-forest bog vegetation.[5]
In Blatná, the river flows through the Blatná Castle park, protected as the Blatná Nature Monument with an area of 43.8 ha (108 acres). It is a site with occurrence of rare and endangered species of animals, especially the hermit beetle, which is highly endangered within the country.[6]
The Lomnice's river bed in the municipality of Smetanova Lhota is protected as the Vystrkov Nature Monument with an area of 2.8 ha (7 acres). It is a site with occurrence of rare and endangered species of plants and animals.[7] A few hundred metres further downstream, the river bed is protected as the V Obouch Nature Monument with an area of 5.1 ha (13 acres). The reasons for protection are similar to Vystrkov.[8]
History
In the Middle Ages, the banks of the Lomnice were popular for gold panning. The so-called sejpy (man-made mounds that are the remains of gold panning) in the castle park in Blatná are protected as a cultural monument.[9]
Tourism
The Lomnice is occasionally suitable for river tourism, but only in spring and after heavy rains. About 23 km (14 mi) of the river is navigable.[10]
