🏛️ Cushman Dam No. 1

Cushman Dam No. 1 is a hydroelectric dam on the North Fork of the Skokomish River in Mason County, Washington, which impounds and enlarges the naturally occurring Lake Cushman. Built by Tacoma City Light between 1923 –1926 as Tacoma's demand for electricity grew rapidly after World War I. Tacoma City Light's Nisqually River Hydroelectric Project, built in 1912, could not meet the demand and the utility decided to build a new hydroelectric project on the North Fork Skokomish River. The dam and powerhouse first began to deliver electricity on March 23, 1926. It has a concrete arch design and includes 90,000 cubic yards of concrete, covering a whole 6,244 feet (1,903 m) of water.
