The fishing industry is centred at Trebon on the Luznice River and dates back to the Middle Ages. Modern dams with their reservoirs have enlarged the industry; the Lipno Dam on the Vltava, in the Sumava Mountains, impounds a 12,350-acre (5,000-hectare) reservoir, provides hydroelectric energy, and helps regulate water levels on the Vltava for navigation and in the fishponds as well. The main lumbering and paper-milling centres are: Cesk udejovice, Vetrn Loucovice, P k, T r, Sobeslav, Pelhrimov, Lisov, and Suchdol nad Luznic The kraj 's relatively few mineral resources include graphite, mined at Vysn-Lazec, Domoradice, Kolodeje, and Blizn peat, extracted at Lenora, Trebon, Pr az, and along the Luznice River; limestone, quarried at Cesk Krumlov and Chnov; asbestos at Borovany; feldspar at Pisek and Halamky; and brick and fire-retardant clays, extracted along the riverbanks. Cesk udejovice is the kraj 's chief industrial centre; it has steelworks and electronics, transport-equi! pment, furniture, pencil, and food-processing plants, as well as several breweries. Tourism is concentrated on water sports, particularly on the reservoir lakes behind the Lipno and Orl dams, and the Svet fishpond; on boat tours along the Vltava and Luznice rivers; and on tours of numerous towns and memorials of the Hussite religious reform movement, which arose in this region. T r, the seat of the Hussite movement (1420), is the site of the Museum of the Hussite Revolutionary Movement; another museum in Kotnov Castle is devoted to T r's history. Trocnov, 19 miles (31 km) southeast of Cesk udejovice, is the birthplace of Jan Zizka, the charismatic military leader of the Hussite army. Hlubok ad Vltavou, 6 miles (10 km) northwest of Cesk udejovice, is the site of the Ales South Bohemian Gallery, exhibiting Gothic and Baroque art.
