Smith River Watershed - Hydrologic Unit 103
The Smith River is an important free-flowing National Wild and Scenic river in the extreme northwestern area of the Region. This 700 square mile watershed provides substantial habitat for a variety of plant, wildlife, and fish species. The river is known for its clear waters, towering redwoods, and diverse forest community that support anadromous steelhead, salmon, and cutthroat trout.
Water Quality, Flow, and Water Rights
2012 Water Quality Assessment Report
Every six years the North Coast Water Board evaluates water quality information and identifies water bodies that do not meet water quality standards and are not supporting their beneficial uses. Those waters are placed on a list of impaired water bodies that identifies the pollutant or stressor causing impairment and establishes a schedule for developing a control plan to address the impairment.
The Smith River has the distinction of not appearing on the list.
