Upper Baker Dam is a dam spanning the Baker River in northern Washington in the United States of America. It is one of two dams on the river, the other one being the Lower Baker Dam a few miles downstream. The dam is used to generate hydroelectricity and provide flood control.[3]

Construction of the dam was finished in 1959 by Puget Sound Energy as part of a power generating scheme, the Baker River Hydroelectric Project. The dam is a concrete gravity structure 312 feet (95 m) high and 1,200 feet (370 m) long, and is capable of producing 91 MW. Its reservoir stretches 9 miles (14 km) upstream and contains 285,000 acre feet (352,000,000 m3) of water.[4]
