About: Navarro River

The Navarro River is a 28.3-mile-long (45.5 km) river in Mendocino County, California, United States. It flows northwest through the Coastal Range to the Pacific Ocean. The main stem of the Navarro River begins less than 1 mile (2 km) south of the town of Philo at the confluence of Rancheria Creek and Anderson Creek. The mouth of the Navarro is 10 miles (16 km) south of the city of Mendocino. State Route 128 starts from the intersection of State Route 1 at the mouth of the Navarro River, and follows the river valley upstream to Philo. The river is close to the highway through the lower canyon but is some distance south of the highway as the Anderson Valley widens upstream of Wendling.
