The Family Forest Fish Passage Program (FFFPP) assists private forestland owners in removing culverts and other stream crossing structures that keep trout, salmon, and other fish from reaching upstream habitat. Road culverts and other structures that are aging, too small, or improperly installed can block fish from reaching their spawning grounds, and young rearing salmon from reaching the ocean. The program funds the replacement of eligible barriers with new structures. 

The program is administered jointly by the Department of Natural Resources, the Washington Department of Fish and Wildlife, and the Recreation and Conservation Office (RCO). The FFFPP is a reimbursement grant program. Project sponsors will have to incur costs upfront and provide expenditure documentation to RCO for reimbursement.
