The construction of the reservoir near Česká Skalice was considered as early as 1923. In 1939, a general project was drawn up, according to which preparations took place in the years 1946–1950. The building of the reservoir dam began in 1951, however after one year of construction, further works were halted. The construction of the dam was resumed in 1965 and completed in 1972. Permission for permanent operation was granted by the Ministry of Forestry and Water Management on 1 January 1976.[2]

A small hydroelectric power plant with installed capacity 675 kW is located on the main dam. The reservoir is also an important ornithological site with more than 270 species of birds, of which more than 120 species nest here.[2]
