The Lake, the dam, the company

The Lake Izvorul Muntelui, also known as Lake Bicaz, was created after the completion of a dam built on

the Bistria River has - on average - a length of 35 km, a perimeter of 71 km, a surface area of 32.6 km

and a maximum volume of 1,250 million cubic meters of water and is also - in size - the second artificial

lake in Romania and the third in height . The powerhouse has four large generating units. Each unit hasa capacity of 130000 kW. The dam is located a few kilometers north of the town of Bicaz. The general

direction of the lake is from northwest to southeast.The lake is a popular tourist destination in the

region, especially in summertime, when visitors can take the ferryboat from the Bicaz port for a short

trip on the lake, enjoying the magnificent view of Mount Ceahlu on the west shore.

The dam was built between 1950 and 1960 and was used to generate hydroelectricity at the Bicaz-

Stejaru hydro-plant until GEG S.A. bought it and upgrade it to a real hydroelectric plant.

GEG.S.A. is a private company with a enviromental vision

How it works

The dam stores lots of water behind it in the reservoir. Near the bottom of the dam wall there is the

water intake. Gravity causes it to fall through the penstock inside the dam. At the end of the penstock

there is a turbine propeller, which is turned by the moving water. The shaft from the turbine goes up

into the generator, which produces the power. Power lines are connected to the generator that carry

electricity to your home and mine. The water continues past the propeller through the tailrace into the

river past the dam.
