Contra Dam (Switzerland)
First on my list of fascinating dams would have to be the Contra Dam or most commonly known as the Verzasca Dam in Ticino, Switzerland. It is perhaps most famous for its 1995 epic appearance in the opening scene of the James Bond movie GoldenEye.
Contra Dam is a slender concrete arch dam standing at a height of 220 m with a crest length of 380 m. Because of the dam's slender design, the volume of concrete required to construct it was reduced and consequently cutting down the cost of the infrastructure. The dam's base is 28 m in width and gradually tapers up to 7 m at the crest. Two spillways were incorporated at each side of the structure, which has a maximum discharge capacity of 1,300 cubic meters per second. Contra Dam also produces power through its 105 MW power station with 3x35 MW Francis turbinesthat generates an average of 234 GWh per year.
Lago di Vogorno is a reservoir that was created and now impounded by the dam when it was constructed between 1961-1965. This reservoir has a maximum capacity of 105,000,000 cubic meters of water and a surface area of 400 acres.
