Klíčava water reservoir, reservoir in Zbečno, Czech Republic
Údolní nádrž Klíčava is a water reservoir in the Křivoklátsko region near Zbečno, surrounded by forests and fed by the Klíčava River and several small streams. The concrete dam stands about 50 meters high and nearly 180 meters long, with a walkable crest offering views over the water and surrounding woodland.
The dam was built between 1948 and 1955 to supply drinking water to Kladno and its surroundings; young religious brothers interned under the Action K campaign were used as labour. The water treatment plant below the dam opened in May 1952 and was rebuilt between 1996 and 1999 to a capacity of 180 litres per second. The reservoir is operated by Povodí Vltavy.
Visitors can walk along the dam crest and explore the surrounding area via marked hiking trails starting from Zbečno or nearby Křivoklát, with red or green trail markers showing the way. The site is accessible by car or on foot, though the inner water protection zone remains restricted to preserve the water source.
The forested island rises where the Klíčava valley meets the valley of the Lánský potok, at the reservoir's widest point. The ruins of Jivno stand on a spur above the water, not on the island itself. The reservoir lies entirely within the Lánská obora game reserve.
