The Lake Izvorul Muntelui, also known as Lake Bicaz, is the largest[1] artificial lake on the interior waters of Romania; it was created after the completion of a dam built on the river Bistrița. The dam is located a few kilometers north of the town of Bicaz.
The dam was built between 1950 and 1960 and is used to generate hydroelectricity at the Bicaz-Stejaru Hydroelectric Power Station. It has a height of 127 m (417 ft), a length of 435 m (1,427 ft), and a maximum width of 119 m (390 ft).
It is a gravity dam made of concrete and connects Mount Gicovanu with Obcina Horștei, located upstream of the confluence of the stream Izvorul Muntelui with Bistrița. Geologically it is located in an area with predominantly siliceous sandstones (Tarcău sandstone), the rest being packages of argillaceous shales and a layer of conglomerates. The foundation soil shows a strong cracking.
Its structure consists of 30 high blocks (plots) separated by joints sealed upstream with reinforced concrete wedges and copper sheeting. It is crossed by galleries, ventilation shafts and manholes. The construction has provided rooms that house drive and control installations, equipment for seismic monitoring and tracking the behavior of each element. At the top, there are four 11.5 m wide spillway fields for a 7 m high water blade (equipped with 6 m segment staves) and four bottom clearings equipped with flat valves (2.50 m diameter) in glasses, arranged in series.
The lake has a length of 40 km (25 mi), an area of 31 km2 (12 sq mi)[1] and a maximum volume of 1,250 billion m³.
The lake is a tourist destination in the region, especially in summertime, when visitors take the ferryboat from the Bicaz port for a short trip on the lake, and to view Mount Ceahlău on the west shore.
In the 1960s and 1970s there was regular ferry service between the Bicaz port and the villages on the lake shore.
At Potoci, a few kilometers north of the town of Bicaz, there is a biological research facility, equipped with a small submersible used for underwater exploration. The facility was visited by the marine biologist Jacques-Yves Cousteau in 1984.
