Williams Lake River Valley Professional Review and Guide
"With its amazing diversity of plant and bird life, the valley is a naturalist's paradise. Black cottonwoods, Douglas fir and white birch are found in different areas, and the multiple habitats ranging from stream, marsh, forest, grasslands and spectacular sandy cliffs attract a great many species of birds.
Pygmy owls and goshawks make the valley their year-round home. Great blue herons inhabit the marshy areas. The more remote western end of the valley is visited by black bear, bobcat, moose and mule deer. Muskrat and mink live along the riverbank and beaver are very active, as evidenced by the chewed birch stumps along the riverbank and the abundant active and deactivated lodges. To really appreciate the varied wildlife calls for an unhurried approach with frequent side trips to view the river."
