Cushman Dam
The 227th tallest dam in the world
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 (now Tacoma Power) 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 (69,000 m3) of concrete, covering a whole 6,244 feet (1,903 m) of water. Construction of the development began by May 23, 1923, with the construction of an incline tram under the commissioner Ira S. Davisson. It has a top width of eight feet (2.4 m) and a base width of 50 feet (15 m), at 275 feet (84 m) high and 1,111 feet (339 m) long. The transmission of electricity to Tacoma, over lines crossing Tacoma Narrows, was dedicated on May 24, 1926, with the push of a button by President Calvin Coolidge in a ceremony at the White House. Although there was a fanciful claim by Davisson later that U.S. President Coolidge "touched the key" that "sent current pulsing from Washington, D.C. into the Olympic Mountains and set the huge turbines whirring", the
