National Culvert Removal, Replacement, and Restoration (Culvert Aquatic Organism Passage)

The purpose of the Culvert AOP Competitive Grant Program is to provide funding to eligible entities for the replacement, removal, and repair of culverts or weirs that meaningfully improve or restore fish passage for anadromous fish.
