Cache Creek possesses extraordinary scenic, recreational, fish, and wildlife values of statewide significance. Prior to state designation, the BLM conducted a federal wild and scenic study of the river and found it to be free flowing and to possess outstandingly remarkable scenic, recreational, wildlife, historical/cultural, and ecological values.
Cache Creek flows through unique geological formations in the Coast Range. Its rugged canyon is clothed in oak woodlands, grasslands, and chaparral, with a lush band of riparian habitat along the creek. The diverse habitat along Cache Creek supports some the largest populations of wintering bald eagles and tule elk in California. Numerous bears forage for fish and other food along the creek. The stream provides a wide variety of outdoor recreation opportunities, including whitewater boating (including a remote 19 mile run through the wilderness), tubing along the highway, hunting, camping, picnicking, and other day use activities. Much of the creek is rich in prehistoric values.
