Hněvkovice Reservoir, reservoir in the Czech Republic

Hněvkovice Reservoir is a large water basin on the Vltava River between Hluboká nad Vltavou and Týn nad Vltavou. The lake spans several kilometers with dikes along its edges that contain the water for power generation and flood control.

Built between 1980 and 2010, the Hněvkovice water works is one of the newest steps of the Vltava cascade, together with Kořensko. Work on the concrete dam itself ran from 1986 to 1991, and the lock was finished in 2010. The reservoir was created mainly to supply cooling water to the Temelín nuclear power plant; the hamlets of Jaroslavice and Buzkov and part of Purkarec were demolished and flooded.

The dam crown carries road III/12220 and cycle route 1079, part of the Vltava cycling path between Hluboká nad Vltavou and Týn nad Vltavou. The lock on the right bank, finished in 2010, handles boats up to 300 tonnes. The reservoir level is kept above 365 m above sea level for the Temelín plant.

Before the reservoir filled, the settlements of Jaroslavice and Buzkov, part of Purkarec, and the hamlets Pardovice and U Bočků were evacuated and demolished. The reservoir's backwater reaches 16.2 km up the Vltava, and water is drawn from it through two 1.6 m pipes running 6.2 km to the Temelín plant.
