History
editThe reservoir was built in 1949–1955. Filling began unplanned in 1954 due to a flood that filled the reservoir within a few days. The construction of a lock was planned, but due to time and financial reasons, it was not implemented.[1]
Purpose
editThe main purpose of the reservoir is to improve the river flow for water transport and for water use, and provision of water for energy use. The reservoir also partially protects the area under the dam (especially the city of Prague) from floods. The dam is also used for fish farming, sports and recreation.[1][3]
The hydroelectric power station is situated at the base of the dam body. It is equipped with three Kaplan turbines.[1]
