Lake Suviana

Lake Suviana (Italian: Lago di Suviana) is an artificial lake located in metropolitan city of Bologna, Italy in the Bolognese Apennines, formed following the construction of a 91.5 m (300 ft) high dam, begun in 1928 and completed in 1932.

[4] The lake is used for production of hydroelectric energy but also for bathing activities, water sports and carp fishing.

The lake is equipped with various refreshment points and bathing facilities which make it a holiday destination during the summer season.

Enel built in 1975 the Bargi hydroelectric power station upstream, which is also powered by the waters of the nearby and overlying Brasimone basin, which is connected to Lake Suviana by a pipeline that exploits the difference in height between the two reservoirs, approximately 384 m (1,260 ft).

This connection, however, is not functional for production, but for "peak-shaving", that is, it is used in production during the hours of maximum demand, while in the hours of minimum load the turbines of the Bargi power plant, being reversible, pump the water back to the Brasimone basin, reconstituting the reserve.
