Stone and Edwin S. Webster in 1889. In the early 20th century, Stone & Webster was known for operating streetcar systems in many cities across the United States including Dallas, Houston and Seattle. The company grew to provide engineering, construction, environmental, and plant operation and maintenance services, and it has long been involved in power generation projects, starting with hydroelectric plants of the late 19th-century; and with most American nuclear power plants.
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. In December 2009 PSE sold the reservoir to the Cascade Water Alliance, a municipal corporation whose members are five King County cities and two water and sewer districts. Cascade provides drinking water to more than 350,000 residents and more than 20,000 businesses. It plans to eventually use Lake Tapps as a municipal water supply source for customers of its members.

The steamboat Monticello (2) operated in the early 1900s as part of the Puget Sound Mosquito Fleet. The vessel went through several reconstructions and remained in service until 1962, when she was lost in Alaska waters. Her later names were Penaco and Sea Venture. (This Puget Sound steamer should not be confused with the smaller Monticello, which also ran on Puget Sound, but was built in 1895 for Captain Z.J. Hatch of the Monticello Steamship Company.

The Enloe Dam, also known as the Similkameen Dam, and its powerplant are located on the Similkameen River about 4 miles (6.4 km) west-northwest of Oroville, Washington. Located just above Similkameen (Coyote) Falls, the concrete arch-gravity dam stands about 54 feet (16 m) high, with a crest length of about 290 feet (88 m), built between 1916 and 1923. The dam was named after the president of the Okanogan Valley Power Company, Eugene Enloe. The dam was operated to generate power at its powerplant, located about 850 feet (260 m) downstream from the dam. Lacking fish ladders, Enloe Dam blocks fish passage and completely extirpated anadromous fish migration into the upper reaches of the Similkameen River and its tributaries in Canada.
Long Lake Dam is a concrete gravity dam on the Spokane River, between Lincoln County and Stevens County about 30 miles (48 km) northwest of Spokane in eastern Washington.

The dam was built by Washington Water Power, which operates five other dams along the Spokane.
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 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.
