Log placement in the West Fork Millicoma creates in-stream habitat for spawning Chinook.

Breeding Coho are actively monitored through weekly spawning surveys.

Oxbow restoration means improved fish passage, reopening over 16 miles of spawning habitat!

Road sediment monitoring, culvert replacement, and bridge building all improve our watershed's accessibility.

Bank stabilization and reduced stream temperatures are some of the benefits of riparian planting.
