Cushman Dam No. 2 is a hydroelectric dam on the North Fork of the Skokomish River in Mason County, Washington, United States, forming Lake Kokanee. Built in 1930, its three 27-megawatt generators provide 233 thousand megawatt-hours annually to the Tacoma Power system. Along with Cushman Dam No. 1, it is part of Tacoma Power's Cushman Project.

Construction began in 1929 and power production began in December 1930. The dam is 575 feet (175 m) long, 8 feet (2.4 m) wide at the top and 40 feet (12 m) at the base. It is 235 feet tall. Its reservoir, Lake Kokanee, is 2 miles (3.2 km) long.[3]
