Nine Mile Falls Dam is a dam on the Spokane River, in the unincorporated community of Nine Mile Falls, Washington. It was built on the site of the falls in 1908, creating Nine Mile Reservoir. The dam was designed by the New York engineering firm of Sanderson & Porter, and originally constructed to satisfy the power needs of the Spokane and Inland Empire Railroad interurban trolley lines. [2]
Washington Water Power (now the power company Avista) purchased the site in 1925, and continues to operate it as one of its six hydroelectric generating plants on the Spokane River. The 58-foot-high cyclopean masonry dam and its powerhouse, storehouse, ten cottages and other structures were placed on the National Register of Historic Places in 1990. [3]
The dam, powerhouse and ten adjacent cottages were added to the National Register of Historic Places in 1990. [4]
The cottages were built in 1928 and 1929 by Washington Water Power as housing for the dam's employees. At the time, the Nine Mile area was remote relative to the residential areas of Spokane, though by the 1990s when the district was added to the NRHP, suburban development had reached the area. The cottages are one-story buildings with large front porches. Each cottage is constructed with brick and features a low-pitched side-gabled roof. Architecturally, the cottages are split between Craftsman and English Cottage styles. In the interior, each cottage consists of three bedrooms, a kitchen, bathroom and living room. Each cottage features a small garage in the back yard. They sit along a tree-line<d road which connects them to the powerhouse in the southwest. They are located on the downstream side of the dam, on a basalt bluff which rises above the river. [4]
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.
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.
Spokane Falls is the name of a waterfall and dam on the Spokane River, located in the central business district in downtown Spokane, Washington. The city of Spokane was also initially named "Spokane Falls".
Nine Mile Falls is an unincorporated community in Spokane County, Washington and Stevens County, Washington, United States. The community straddles the Spokane River 9 miles (14 km) away from downtown Spokane, at the location of a former falls that has been the site of Nine Mile Dam since 1908. Following the river, the community is located 16 miles (26 km) downstream from downtown.
Lake Tapps is a reservoir in Pierce County, Washington. It was created in 1911 by Puget Sound Power & Light and operated for hydroelectric power until it ceased power production in 2004. The reservoir was sold to the Cascade Water Alliance, a collective of municipalities in King County, to provide drinking water to 350,000 residents and 20,000 businesses.
The Skagit River Hydroelectric Project is a series of dams with hydroelectric power-generating stations on the Skagit River in northern Washington State. The project is owned and operated by Seattle City Light to provide electric power for the City of Seattle and surrounding communities.
Diablo Dam is one of three dams along the upper Skagit River in Whatcom County, Washington and part of the Skagit River Hydroelectric Project that supplies Seattle with some of its power needs. The dam was built in Diablo Canyon, a gorge of solid granite with vertical walls rising 160 feet (49 m) from the river bed, yet were less than 100 feet (30 m) apart. Construction began in 1927, and was completed in 1930. The dam began generating electricity in 1936.
Hungry Horse Dam is an arch dam in the Western United States, on the South Fork Flathead River in the Rocky Mountains of northwest Montana. It is located in Flathead National Forest in Flathead County, about fifteen miles (24 km) south of the west entrance to Glacier National Park, nine miles (14 km) southeast of Columbia Falls, and twenty miles (32 km) northeast of Kalispell. The Hungry Horse project, dam, and powerplant are operated by the U.S. Bureau of Reclamation. The entrance road leading to the dam is located in Hungry Horse.
Cabinet Gorge Dam is a concrete gravity-arch hydroelectric dam in the northwest United States, on the Clark Fork River in northern Idaho. The dam is located just west of the Montana border and the Cabinet Gorge Reservoir extends into Montana, nearly to Noxon Rapids Dam. The purpose of the dam is for hydroelectricity.
Noxon Rapids Dam is an earthfill gravity-type hydroelectric dam on the Clark Fork river, in the northwest part of the U.S. state of Montana.
Swan Falls Dam is a concrete gravity type hydroelectric dam in the western United States, on the Snake River in southwestern Idaho, United States. At the dam, the river is the border of Ada and Owyhee counties; it is approximately five miles (8 km) east of Murphy, the seat of Owyhee County.
Rainbow Dam is a hydroelectric dam on the Missouri River, 29 feet (8.8 m) high and 1,055 feet (322 m) long, located six miles northeast of Great Falls in the U.S. state of Montana.
Ryan Dam is a hydroelectric dam on the Missouri River, 10 miles (16 km) downstream from the city of Great Falls in the U.S. state of Montana. The dam is 1,336 feet (407 m) long and 61 feet (19 m) high; its reservoir is 7 miles (11 km) long and has a storage capacity of 5,000 acre-feet (6,200,000 m3). It is a run-of-river dam. The dam is built on the largest of the five Great Falls of the Missouri, the "Big Falls", also sometimes called "Great Falls". Since 1915, the six-unit powerhouse on the left side of the dam has occupied a significant portion of the 87-foot (27 m) high waterfall.
Hardy Dam is an earth-filled embankment dam and powerplant complex on the Muskegon River in Big Prairie Township, Newaygo County, Michigan. At the time of its completion, it was the largest earthen dam in North America east of the Mississippi. Its impoundment forms a lake with over 50 miles of shoreline. The dam impounds a reservoir with a surface area of 4,000 acres and its power plant has an installed capacity of 31.5 MW.

The Big Creek Hydroelectric Project is an extensive hydroelectric power scheme on the upper San Joaquin River system, in the Sierra Nevada of central California. The project is owned and operated by Southern California Edison (SCE). The use and reuse of the waters of the San Joaquin River, its South Fork, and the namesake of the project, Big Creek – over a vertical drop of 6,200 ft (1,900 m) – have over the years inspired a nickname, "The Hardest Working Water in the World".
The Snoqualmie Falls Hydroelectric Plant is located just north of Snoqualmie in King County, Washington state, US. It is situated about 22 mi (35 km) east of Seattle. Located just below the Snoqualmie Falls, the power plant consists of two power houses, Plant 1 and Plant 2. Plant 1 was completed in 1899 and is located underground. It is the first completely underground hydroelectric power plant ever built in the world. Plant 2 was built in 1910 and is located along the right bank of the Snoqualmie River. Both plants receive water from a small reservoir created by a weir atop the falls. Plant 1 has an installed capacity of 13.7 MW and Plant 2 a capacity of 40.2 MW for a total installed capacity of 53.9 MW, enough to power 40,000 homes.
Seattle Municipal Light and Power Plant, also known as Cedar Falls Historic District, is a public hydroelectric plant near North Bend, Washington operated by Seattle City Light. The plant was the first publicly-owned electrical generating plant for Seattle and one of the earliest in the country for a municipality of its size. It was listed on the National Register of Historic Places in 1997.
