Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over 100 lives. It was referred to as the Hoover Dam after President Herbert Hoover in bills passed by Congress during its construction; it was named the Boulder Dam by the Roosevelt administration. The Hoover Dam name was restored by Congress in 1947.

The majority of it is owned by the U.S. Bureau of Reclamation and is managed by the California Department of Parks and Recreation. It is located near the city of Folsom, California, about 25 miles (40 km) east of Sacramento.
A kettle is a depression or hole in an outwash plain formed by retreating glaciers or draining floodwaters. The kettles are formed as a result of blocks of dead ice left behind by retreating glaciers, which become surrounded by sediment deposited by meltwater streams as there is increased friction. The ice becomes buried in the sediment and when the ice melts, a depression is left called a kettle hole, creating a dimpled appearance on the outwash plain. Lakes often fill these kettles; these are called kettle hole lakes. Another source is the sudden drainage of an ice-dammed lake and when the block melts, the hole it leaves behind is a kettle. As the ice melts, ramparts can form around the edge of the kettle hole. The lakes that fill these holes are seldom more than 10 m (33 ft) deep and eventually fill with sediment. In acid conditions, a kettle bog may form but in alkaline conditions, it will be kettle peatland.
Fort Peck Lake, or Lake Fort Peck, is a major reservoir in Montana, formed by the Fort Peck Dam on the Missouri River.

Part of its 193-square-mile (500 km2) watershed is in Putnam County to the south. Sprout Creek, the county's third-longest creek, is its most significant tributary. Whaley and Sylvan lakes and Beacon Reservoir, its largest, deepest and highest lakes, are among the bodies of water within the watershed.

The park primarily consists of woodlands south of the Long Island Expressway and meadowlands north of the expressway. It is run and operated by the New York City Department of Parks and Recreation.
Ridgewood Reservoir is a decommissioned 19th century reservoir and freshwater wetland on the border between the New York City boroughs of Brooklyn and Queens, within what is now Highland Park. Although the reservoir was originally built to secure a reliable water supply for the City of Brooklyn, it is positioned on the Queens side of the border in the neighborhood of Glendale. The reservoir and park are bounded on the north by the Jackie Robinson Parkway, on the south by Highland Boulevard, on the west by Vermont Place and on the east by Cypress Hills National Cemetery.
The Ramble and Lake are two geographic features of Central Park in Manhattan, New York City. Part of Frederick Law Olmsted and Calvert Vaux's 1857 Greensward Plan for Central Park, the features are located on the west side of the park between the 66th and 79th Street transverses.
Lake Cochituate is a body of water in Natick, Wayland, and Framingham, Massachusetts, United States. Originally a reservoir serving Boston, it no longer serves that function, and is now a local recreational resource and home to Cochituate State Park.
The Mousam River is a 29.7-mile-long (47.8 km) river in York County, Maine, United States. Its primary source is Mousam Lake, located between the towns of Shapleigh and Acton, and it flows into the Atlantic Ocean just west of Kennebunk Beach. It flows through the towns of Shapleigh, Sanford and Kennebunk.
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.
Lake Innisfree is a man-made lake and former reservoir in the city of New Rochelle and the town of Eastchetser, in Westchester County, New York. Its eastern end abuts the Hutchinson River Parkway. The lake takes its name from the poem Lake Isle of Innisfree by W. B. Yeats.
Oil sands tailings ponds are engineered dam and dyke systems used to capture oil sand tailings. Oil sand tailings contain a mixture of salts, suspended solids and other dissolvable chemical compounds such as acids, benzene, hydrocarbons residual bitumen, fine silts and water. Large volumes of tailings are a byproduct of bitumen extraction from the oil sands and managing these tailings is one of the most difficult environmental challenges facing the oil sands industry. An October 2021 Alberta Energy Regulator (AER) report said that in 2020 the tailings ponds increased by another 90 million cubic meters and contained 1.36 billion cubic metres of fluids.
The H.F. Lee Energy Complex, formerly the Goldsboro Plant, is an electrical power generating complex operated by Duke Energy. The power complex was originally owned by the Carolina Power & Light Company, which inaugurated a coal-fired power plant in 1951. Two more coal plants were added in 1952 and 1962, and then oil-fueled turbines were added in 1967–71. In 2012 these units were shut down and replaced by four gas-fired units. The Quaker Neck Lake was built as a cooling pond for the coal-fired power stations, and is still used to supply cooling water. It was originally impounded by a low dam on the Neuse River, but in 1998 the dam was removed, while the lake remained contained in an earthen wall. This change allowed fish to migrate further upstream for spawning. Ash ponds near the lake hold toxic coal ash. There are plans to remove and recycle or bury the ash.
The Barton Dam is a hydroelectric barrage dam crossing the Huron River. It is located in the city of Ann Arbor in Washtenaw County in the U.S. state of Michigan. It began operating in 1912 and currently provides hydroelectricity to city of Ann Arbor, which owns and maintains the dam and power station.
