Corpsmembers work with Department of Fish and Game biologists to restore the environment to a more balanced state by adding structures that mimic nature. Made primarily of wood and rock, these structures provide shelter for fish, help reduce water temperatures and add complexity to the stream channel ensuring that adult salmon have the habitat they need to spawn and juvenile salmon have a healthy environment in which to grow.

Corpsmembers set up complex "grips" or pulls for giant redwood logs using pulleys, wire cable, grip hoists, teamwork and field know-how.

After maneuvering the heavy logs into place, corpsmembers secure them using rebar.

The installed "digger logs" create hydrological forces that will deepen the stream channel and create a pool.

The resulting pool created by corpsmembers, digger logs and mother nature, provides habitat and cover for spawning salmon as well as shade to cool water temperatures.
