Box Canyon Dam is a gravity-type hydroelectric dam on the Pend Oreille River, in northeastern Washington state in the United States.

It has a capacity of 90 MW and an average expected production of 60 MW. The reservoir extends 55 miles (89 km). The dam is 160 feet (49 m) wide and 62.4 feet (19.0 m) high at the top of the gates. The maximum head of water is 46 feet (14 m). It produces power using four Kaplan turbines. An upgrade completed in 2015 brought the dam's rated capacity up to 90 MW from the original 69 MW.[1]
