The Smith River is a 104-mile long river located in northwest California. It flows through Del Norte and Siskiyou counties and eventually empties into the Pacific Ocean. The river has a rich history and was once home to various Native American tribes. Today, it is known for its recreational activities, including fishing, boating, and camping. The river's hydrology is influenced by the Klamath Mountains and its numerous tributaries. There are no major dams along the Smith River, but there are several small reservoirs that provide water for agricultural purposes. The river is also used for irrigation and livestock watering. The Smith River is considered one of the cleanest rivers in the United States, and efforts are being made to preserve its unique ecosystem.
