Bear River Dam (National ID # CA00379, also known as the Upper Bear River Dam) is a dam in Amador County, California,[1] due east of Sacramento.

The rockfill dam was constructed in 1900 (124 years ago) (1900) with a height of 83 feet (25 m), and a length of 748 feet (228 m) at its crest.[2] It impounds the Bear River for hydroelectric power generation and municipal water supply. It is owned and operated by Pacific Gas and Electric Company, the largest private owner of hydroelectric facilities in the United States, making it one of the company's 174 dams.

The reservoir it creates, Bear River Reservoir, has a normal water surface of 149 acres (60 ha) and has a maximum capacity of 6,818 acre-feet (8,410,000 m3).[3] Recreation includes fishing, swimming, and camping,[4] however the Upper Bear River Reservoir can only be accessed by foot, and is mostly unused by the public.

The Lower Bear River Reservoir and its own dam lie immediately downstream and to the west, also owned by PG&E.

The dam is being examined as the upper pool in a 380–1,140 MW pumped-storage project with the Salt Springs Reservoir as the lower pool.[5]
