Discharges of dredged or fill material into waters of the United States and structures and work in navigable waters of the United States for activities that restore or enhance the ability of fish and other aquatic organisms to move through aquatic ecosystems. Examples of activities that may be authorized by this NWP include, but are not limited to: the construction, maintenance, modification, or expansion of conventional/technical and nature-like fishways; the construction, maintenance, modification, or expansion of fish bypass channels around existing in-stream structures; the replacement of existing structures (e.g., culverts, low-water crossings) with structures planned, designed, and constructed to restore or enhance passage of fish and other aquatic organisms; the installation of fish screens and other devices to minimize entrainment and entrapment of fish and other aquatic organisms in irrigation ditches and other features; devices to guide fish and other aquatic organisms through passage features; fish lifts and fish by-pass pipes; the modification of existing in-stream structures, such as dams or weirs, to improve the ability of fish and other aquatic organisms to move past those structures.
