Švihov Reservoir, Major water reservoir in Zruč nad Sázavou, Czech Republic.

The Švihov Reservoir, also called Želivka, is a drinking-water reservoir on the Želivka River in central Bohemia, held by a 58-metre-high earth dam with an 860-metre crest. Its 14.3 km² surface fills the narrow valleys of the Želivka and its tributaries, and a road bridge on State Road 150 crosses an arm between Brzotice and Bezděkov.

Construction began in the 1960s and led to the relocation of thousands of residents from several villages. The facility was created to meet the growing water needs of the capital.

The visitor center in Hulice shows how drinking water is treated for millions of people. Visitors can use interactive stations that explain the journey of water from the reservoir to households.

Visitors can walk along the shore roads and view the water from several lookout points. Access to the water itself is restricted to protect its quality.

Above the water near Borovsko stands the unfinished concrete arch bridge of the never-completed Prague–Jihlava motorway, begun in 1939 and abandoned in 1942 after the attack on Reinhard Heydrich; work resumed in 1948–1950 but the south side was never finished. Locals call it the Hitler Bridge, and it now rises about 36 metres above the reservoir.
