Bear River

The Bear River is a tributary of the Feather River in the Sierra Nevada, winding through four California counties: Yuba, Sutter, Placer, and Nevada. About 73 miles (117 km) long, the river flows generally southwest through the Sierra then west through the Central Valley, draining a narrow, rugged watershed of 295 square miles (760 km2).
The California Office of Environmental Health Hazard Assessment has issued a safe advisory for any fish caught in Bear River due to elevated levels of mercury.
