In the northeastern United States several guidance, protection, and conveyance methods have been employed to assist downstream migrating fish. Overlay racks, standard bar racks with close spacing, louvers, curtain walls, guide walls, netting, and other means have been used to guide and protect fish from entrainment. The design process of these facilities comprises consideration of various factors, including flow approach, attraction flow, guidance and protection devices, bypass location, conveyance mechanism, and plunge pool conditions. This paper presents the status of the design criteria for downstream fish passage facilities at hydroelectric sites in the northeast part of the United States. Examples of existing facilities are given.
