The concrete dam "Presa Valle Grande" backs up the reservoir "Embalse Valle Grande" (Rio Atuel). The dam is 115 m tall, the crest is 300 m long, the flood spillway has a capacity of 512 m³/s. The hydro power plant "Nihuil IV" opened in 1997. - If the spillway goes in operation, the camping site is not recommendable ;-) - scanned slide, Minolta X700

Hoover Dam is protected against an uncontrolled overflow by two flood spillways, one on the Nevada side and the other one the Arizona side. The spillways are controlled by drum gates and the overflow goes into side channels and huge 15 m wide tunnels to the tailwater. The total capacity is 11000 m³/s. The large spillway tunnels have only been used twice, for testing in 1941 and because of flooding in 1983.
