The Rubicon Hydroelectric Scheme is a small run-of-the-river hydroelectric scheme located on the Rubicon and Royston Rivers, north east of Melbourne, 40 km (25 mi) south-west of Alexandra, Victoria, Australia. The scheme commenced in 1922, and was the first state-owned hydroelectric scheme to generate electricity in mainland Australia, and among the first in the world to be remotely controlled. For the first ten years of its operation it supplied on average 16.9% of electricity generated by the State Electricity Commission of Victoria. It is now owned and operated by AGL Energy and contributes approximately 0.02% of Victoria's energy supply.

The Nathpa Jhakri Dam is a concrete gravity dam on the Sutlej river in Himachal Pradesh, India. The primary purpose of the dam is hydroelectric power production and it supplies a 1,500 megawatts (2,000,000 hp) underground power station with water. Before reaching the power station, water is diverted through a 27.4 km (17 mi) headrace tunnel. Construction on the project began in 1993 and it was complete in 2004. The last two of the 250 megawatts (340,000 hp) Francis turbine-generators went online in March 2004. It is owned by SJVN Ltd
Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage. A plant without pondage is subject to seasonal river flows, thus the plant will operate as an intermittent energy source. Conventional hydro uses reservoirs, which regulate water for flood control, dispatchable electrical power, and the provision of fresh water for agriculture.
Frank D. Comerford Dam is an International Style concrete dam in the Fifteen Mile Falls of the Connecticut River, on the border between the U.S. states of New Hampshire and Vermont. The dam is near Monroe, New Hampshire and Barnet, Vermont. Construction began in 1928 and was completed in 1931. The dam and the power plant were acquired by Great River Hydro, LLC, from TransCanada Corporation in April 2017.

It is about 59 kilometres (37 mi) downstream from the Guri Dam belonging to the Central Hidroeléctrica Simón Bolívar, and about 35 kilometres (22 mi) from where the Caroni and Orinoco rivers meet at Ciudad Guayana.
The Koombooloomba Dam is a concrete gravity dam with a controlled spillway across the Tully River, located west of Tully and south, southeast of Ravenshoe in Far North Queensland, Australia. Built for the purpose of hydroelectric power generation, the dam creates the reservoir, Lake Koombooloomba.
Graham Lake in Hancock County, Maine is a eutrophic reservoir formed by the construction of a hydro-electric power dam in 1922 four miles (6 km) upstream from Ellsworth, Maine. The first dam was a hastily built earthen dam built by the Bangor Hydro Electric Company. It failed in 1923, flooding downtown Ellsworth and doing almost $8 million in property damage. The dam was rebuilt and operated by Bangor Hydro until its sale in 1999. The dam has since been acquired by Pennsylvania Power & Light which continues to use it to generate electricity.
The Jean-Lesage generating station, formerly known as Manic-2, is a dam located 22 km from Baie-Comeau built on Manicouagan River in Quebec, Canada. It was constructed between 1961 and 1967. On June 22, 2010, the dam and the generating station were renamed in honour of Jean Lesage, who was premier of Quebec during the construction of the complex.
Smith Mountain Dam is a concrete arch dam located on the Roanoke River in Virginia, creating Smith Mountain Lake. The dam was built by Appalachian Power between 1960 and 1963 for the purposes of pumped-storage hydroelectricity. The dam created Smith Mountain Lake as its reservoir, where recreation and real estate have become popular.
Richard B. Russell Dam is a concrete-gravity and embankment dam located on the Savannah River at the border of South Carolina and Georgia, creating Richard B. Russell Lake. The dam was built by the U.S. Army Corps of Engineers between 1974 and 1985 for the purposes of flood control, hydroelectricity, recreation, additional stream flow regulation, water supply, and fish and wildlife management. The concrete structure of the dam spans 1,904 feet (580 m) and rises 210 feet (64 m) above the riverbed, housing a hydro-power plant with an installed 600 megawatts (800,000 hp) capacity. The Richard B. Russell Dam is the final large dam completed by the U.S. Army Corps in the Savannah River Basin and lies 30 miles downstream from the Hartwell Dam (1962) and 37 miles (60 km) upstream from the J. Strom Thurmond Dam (1954).
Hauser Dam is a hydroelectric straight gravity dam on the Missouri River about 14 miles (23 km) northeast of Helena, Montana, in the United States. The original dam, built between 1905 and 1907, failed in 1908 and caused severe flooding and damage downstream. A second dam was built on the site in 1908 and opened in 1911 and comprises the present structure. The current Hauser Dam is 700 feet (210 m) long and 80 feet (24 m) high. The reservoir formed by the dam, Hauser Lake, is 25 miles (40 km) long, has a surface area of 3,800 acres (1,500 ha), and has a storage capacity of 98,000 acre-feet (121,000,000 m3) of water when full.
Cochrane Dam is a run-of-the river hydroelectric dam on the Missouri River, about 8 miles (13 km) northeast of Great Falls in the U.S. state of Montana. The dam has a concrete gravity design and is 59 feet (18 m) high and 753 feet (230 m) long. Its power station has two generators capable of producing 64 megawatts. Construction of the dam was finished in 1958. Montana Power Company originally built the dam, PPL Corporation purchased it in 1997 and sold it to NorthWestern Corporation in 2014.

Kyiv Hydroelectric Station is a run-of-river power plant on the Dnieper River in Vyshhorod, Ukraine. The 288 m (945 ft) long dam creates the Kyiv Reservoir with the purpose of hydroelectric power generation and navigability with the dam's associated lock. The first of 20 generators in the power station was commissioned in 1964, the last in 1968. Together with the Kyiv Pumped Storage Power Station, it creates a hydroelectricity generating complex. It is operated by the Ukrhydroenergo. Turbines for the plant were produced by the Kharkiv Factory Turboatom, and generators by the Kharkiv Factory "Elektrovazhmash".
La Trenche Generating Station is a hydroelectric power plant on the Saint-Maurice River and within La Tuque, in Upper-Mauricie, in the administrative region of Mauricie, in Quebec, in Canada. Its construction was completed in 1950. This power station was put into service immediately. It is the central 6th to block the river from its mouth. With its 302 megawatts (405,000 hp), it is the most powerful. Hydro-Québec acquired La Trenche power from the Shawinigan Water & Power Company.
The Electron Hydroelectric Project, originally known as the Puyallup Project, is a hydroelectric power plant operated by Electron Hydro LLC on the Puyallup River in Pierce County, Washington. It generates 22 megawatts (30,000 hp) of electricity and is operated and maintained by approximately 20 full-time employees.
The Brookfield Renewables Milford Dam, also known as the Milford Dam of Versant Power, is a hydroelectric power generation facility on the Penobscot River in Milford, Maine. Its main building, a handsome Romanesque structure, stands at the eastern end of the Milford Dam.
