The Třeboň Basin is one of the mesoregions of the South Bohemian Basins (the second being the České Budějovice Basin) within the Bohemian Massif. It is further subdivided into the microregions of Lišov Threshold, Lomnice Basin and Kardašova Řečice Uplands.[1]
Relief varies across the territory. In the middle the relief is flat, in the east there is a flat hilly relief, and in the west there is an asymmetrical ridge with a rugged hilly relief.[2]
The highest part of the territory is the western part, in Lišov Threshold, where altitudes are above 500 metres (1,600 ft). There is also the highest peak of the territory, Baba at 583 metres (1,913 ft) above sea level.
The Třeboň Basin was tectonically formed during the Cretaceous. It is filled with sediments from the Late Cretaceous and Neogene periods, in the west there are sediments from the Permian period, on the edge there is a Moldanubicum.[2][3]
The Třeboň Basin has an area of 1,360 km2 (530 sq mi) and an average elevation of 457 m (1,499 ft).[2] The territory has a slightly elongated shape from north to south and stretches from the town of Soběslav in the north to the Czech-Austrian border in the south. The border passes around České Budějovice in the west and Jindřichův Hradec in the east, both cities are already outside the territory.
The area is densely interwoven with many watercourses. The largest rivers are Lužnice and Nežárka. Part of the territory also belongs to the Vltava river basin. The Vltava briefly crosses the west of the territory.[2]
Despite the area, there are no larger settlements, and the territory is sparsely populated. The largest towns in the Třeboň Basin are Třeboň, Veselí nad Lužnicí, Lišov, Suchdol nad Lužnicí and České Velenice.
Ponds
The Třeboň Basin is known for its fish ponds, which were established in the region since Middle Ages. There are the largest ponds in the Czech Republic, including Rožmberk, Horusický, Dvořiště, Velký Tisý and Záblatský. Rožmberk Pond is the largest pond in the country and the largest fish pond in the world with surface area of 489 hectares (1,210 acres). It was built between 1584 and 1590.[4]
A large part of the basin (about 700 km2 (270 sq mi)) is protected as the Třeboňsko Protected Landscape Area. Since 1977, Třeboňsko also has been one of six Czech UNESCO MAB biospheric reserves.[5]
