Chief Joseph Dam - Type

Type

Chief Joseph Dam is a run-of-the-river dam which means the lake behind the dam is not able to store large amounts of water. Water flowing to Chief Joseph Dam from Grand Coulee Dam must be passed on to Wells Dam at approximately the same rate. With 27 main generators in the powerhouse, it has the hydraulic capacity of 6,030 m3/s (213,000 cu ft/s).

In the event more water flows to Chief Joseph Dam than could be used for power generation, the spillway gates would be opened to pass the excess water. With an average annual flow rate of 3,058 m3/s (107,992 cu ft/s), the Columbia River seldom exceeds the powerplant’s capability to pass water, and spilling of water is infrequent at Chief Joseph Dam.

Famous quotes containing the word type:

    The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.
    Freda Adler (b. 1934)

    The Republican form of government is the highest form of government; but because of this it requires the highest type of human nature—a type nowhere at present existing.
    Herbert Spencer (1820–1903)

    Under the species of Syndicalism and Fascism there appears for the first time in Europe a type of man who does not want to give reasons or to be right, but simply shows himself resolved to impose his opinions.
