Right next to the restaurant Český Krumlov bar The Strojovna, you can find the hydropower plant. The river rises in southwestern Bohemia from two headstreams in the Bohemian Forest, the Tepla Vltava and the Studena Vltava. It flows first southeast, then north across Bohemia, and empties into the Elbe (Czech: Labe) River at Melnik, 18 miles (29 km) north of Prague.
