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 27,000 kilowatt generators provide 233 million kilowatt-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]

The Skokomish River is a river in Mason County, Washington, United States. It is the largest river flowing into Hood Canal, a western arm of Puget Sound. From its source at the confluence of the North and South Forks the main stem Skokomish River is approximately 9 miles (14 km) long. The longer South Fork Skokomish River is 40 miles (64 km), making the length of the whole river via its longest tributary about 49 miles (79 km). The North Fork Skokomish River is approximately 34 miles (55 km) long. A significant part of the Skokomish River's watershed is within Olympic National Forest and Olympic National Park.

<span class="mw-page-title-main">Cushman Dam No. 1</span> United States historic place

Cushman Dam No. 1 is a hydroelectric dam on the North Fork of the Skokomish River in Mason County, Washington, which in derogation of the natural and treaty rights of the Native inhabitants impounded and enlarged the formerly natural Lake Cushman, leading to damage claims in excess of $5 billion and an eventual settlement agreement with the Skokomish tribe that terminates the right to operate the dam(s) after 2048. It was built by Tacoma City Light in 1924–1926. 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 February 12, 1926.

<span class="mw-page-title-main">Tieton Dam</span> Dam in Washington, USA

Tieton Dam is an earth and concrete type dam on the Tieton River in Yakima County, in the U.S. state of Washington. The dam began operation in 1925. Its reservoir, Rimrock Lake, has a total capacity of 203,600 acre-feet (0.2511 km3) with a normal operating capacity of 198,000 acre-feet (0.244 km3) to provides water for agricultural irrigation. This dam is a component of the Yakima Project. Tieton Dam also produces electricity for Burbank Water and Power and Glendale Water and Power, near Los Angeles. The Southern California Public Power Agency installed two 7 megawatt generators in a project started in 2010. The power is transmitted over the DC Intertie that runs from Celilo, Oregon to Sylmar, California. Upstream from the dam, the river is impounded by Clear Creek Dam, another element of the Yakima Project. About 8 miles (13 km) downstream from the dam, the Tieton River is tapped for the Tieton Main Canal.
