fish screen
A fish screen is a barrier to prevent fish from swimming or being drawn into an aqueduct, cooling water intake, dam intake tower, or other diversion on a river, lake, reservoir, or waterway where water is taken for human use. It supplies debris-free water with limited harm to aquatic life. Fish screens are typically installed to protect endangered species 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.
