State and federal agencies have collaborated on watershed restoration work, including the removal of man-made barriers to fish migration, decommissioning of old logging roads and installation of culverts to reduce erosion. In September 2014, the Hammer Dam on the South Fork of Cottonwood Creek was removed, opening up of habitat for spring-run Chinook and steelhead. As of 2009, the U.S. Fish and Wildlife Service has allocated $10 million for watershed restoration projects.
