A fish screen is designed to prevent fish from swimming or being drawn into an aqueduct, cooling water intake, dam or other diversion on a river, lake or waterway where water is taken for human use. They are intended to supply debris-free water without harming aquatic life. Fish screens are typically installed to protect endangered species of fishes that would otherwise be harmed or killed when passing through industrial facilities such as steam electric power plants, hydroelectric generators, petroleum refineries, chemical plants, farm irrigation water and municipal drinking water treatment plants. However, many fish are killed or injured on screens or elsewhere in the intake structures.

Famous quotes containing the words fish and/or screen:
“Let a man get up and say, “Behold, this is the truth,” and instantly I perceive a sandy cat filching a piece of fish in the background. Look, you have forgotten the cat, I say.”
—Virginia Woolf (1882–1941)
“She was custom built for the pictures—teeny tiny, one inch less than five foot, and a perfectly enormous head. Her face went right from one side of the screen to the other. Gloria Swanson was like that, as well. Joan Crawford, too. You need the big face, for the closeups.”
—Angela Carter (1940–1992)
