Family Forest Fish Passage Program (FFFPP)


The Family Forest Fish Passage Program is a funding program through the Washington State Department of Natural Resources for small forest landowners to improve fish passage, by replacing impassible culverts with engineered bridges.

Culverts can be fish barriers
Culverts can be fish barriers

What makes a culvert a fish barrier?

  • Outfall drop from a culvert may create a barrier for both adult and juvenile fish, especially Chum Salmon who are not great jumpers.
  • Undersized culverts create high water velocity and this can be a barrier to fish, especially juvenile fish.
  • Culverts can become plugged, blocking passage for fish.

Who’s eligible for funding?

  • If you are a private, small forest landowner harvesting less than 2 million board feet of timber each year from lands you own in Washington
  • The culvert is on forestland and associated with a road. The land is capable of supporting a merchantable stand of timber and is not being used for anything incompatible with growing timber.
  • The culvert is on a fish-bearing stream wider than 2 feet and on a gradient less than 20%.
