The National Fish Passage Program (NFPP) provides technical and financial assistance to partners to remove instream barriers and restore aquatic connectivity, improve community safety, and support local economies. Fish passage projects benefit communities by reducing flood risk, improving recreational opportunities, and improving roads while supporting native fish populations and aquatic ecosystems. NFPP project examples include obsolete and dangerous infrastructure removals, culvert replacements, floodplain restoration, and the installation of fishways. It is estimated that for every $1 million invested by the program, $1.5 million in value is added to the economy.The program is delivered through U.S. Fish and Wildlife Service (Service) field offices nationwide. Local Service staff work with partners to identify and implement projects. Projects are based on sound science, advance the Service mission, and promote aquatic connectivity.
