What the grant funds
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. Anadromous fish are born in freshwater and spend most of their lives in saltwater, returning to freshwater to spawn. Salmon are a well-known example of anadromous fish.
