In many American communities, rivers irrigate the farms that feed families, quench people’s thirst—rivers are the source of more than two-thirds of the drinking water in the U.S.—sustain wildlife habitat, and provide an economic boost for communities. Yet only a very small portion of those waterways are protected from threats ranging from pollution to damming, which would wreck the water’s natural flow. … California’s Regional Water Quality Control Boards have authority to designate ONRWs but to date have done so for only two bodies of water: Lake Tahoe and Mono Lake. However, the state did initiate an analysis of the Smith River as an ONRW but has not completed the effort. The Smith is a Pacific salmon stronghold.
