Components
The main reservoir of the scheme is the Rocky Valley Dam, which has a capacity of 28 billion litres and is situated at 1600 metres above sea level. The scheme also contains a number of smaller dams and pondages. A great deal of the water in the dams comes from melting snow, which covers much of the area during cooler months.
Linking the reservoirs and power station are 11 miles (18 km) of tunnels, and 32 km of aqueducts. The scheme consists of four power stations:

Famous quotes containing the word components:
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
