Fort Nelson River: The Fort Nelson River is in north-eastern British Columbia, Canada.  It flows 517 km generally north-westward to the Liard River, a tributary of the Mackenzie River, which empties into the Arctic Ocean.  The river drains a watershed of 55900 km2 and is formed by the confluence of the Fontas River flowing from the east, and the Sikanni Chief River flowing from the south.  These, along with the Sahtaneh and Muskwa Rivers constitute the major tributaries.  The source of the Sikanni Chief, on the eastern slope of the Rocky Mountains, is ultimately the headwater of the Fort Nelson River.

Lake Red Rock (Des Moines River): Originally the city of Red Rock, Lake Red Rock, also referred to as Red Rock Reservoir is a reservoir formed by Red Rock Dam on the Des Moines River, about 55 miles southeast of the city of Des Moines, Iowa, United States.  The dam was completed in 1969 as a flood control project by the United States Army Corps of Engineers, creating the largest lake in Iowa.  The lake is essentially confined to Marion County.  The damface is a few miles west and south of Pella, and similarly, a few miles northeast of Knoxville.

Theodore Roosevelt Lake: Theodore Roosevelt Lake (usually called Roosevelt Lake, sometimes Lake Roosevelt) is a large reservoir formed by Theodore Roosevelt Dam on the Salt River in Arizona as part of the Salt River Project (SRP).  Located roughly 80 miles (130 km) northeast of Phoenix in the Salt River Valley, Theodore Roosevelt is the largest lake or reservoir located entirely within the state of Arizona (Lake Mead and Lake Powell are larger but both are located partially within the neighboring states of Nevada and Utah respectively).  Both the reservoir and the masonry dam that created it, Roosevelt Dam, were named for U.S. President Theodore Roosevelt who dedicated the dam himself in March 1911.  Roosevelt Lake is a popular recreation destination within the Tonto National Forest, as such the facilities located at this lake are managed by that authority.

Narva River: The Narva (Estonian: "Narva jõgi" , Russian: Нарва ) (or Narova) is a river flowing into the Baltic Sea, the largest river in Estonia by discharge.  Draining Lake Peipsi, the river forms the border of Estonia and Russia and flows through the towns of Narva/Ivangorod and Narva-Jõesuu into Narva Bay.  Though the river is only 77 km long, in terms of volume discharged it is the second largest river flowing into the Gulf of Finland.  The river gives its name to the Narva culture and the city of Narva.

Cherokee Dam: Cherokee Dam is a hydroelectric dam located on the Holston River in Grainger County and Jefferson County, Tennessee, in the southeastern United States.  The dam is operated and maintained by the Tennessee Valley Authority, which built the dam in the early 1940s to help meet urgent demands for energy at the outbreak of World War II.  Cherokee Dam is 175 ft high and impounds the 28780 acre Cherokee Lake.  It has a generating capacity of 135,200 kilowatts.  The dam was named for the Cherokee, a Native American tribe that controlled much of East Tennessee when the first European settlers arrived in the mid-18th century.

Chusovaya River: The Chusovaya River (Russian: Чусова́я ) is a river flowing in Perm Krai, Sverdlovsk Oblast and Chelyabinsk Oblast of Russia.  A tributary of the Kama River, which in turn is a tributary of the Volga River, it discharges into the Chusovskoy Cove of the Kamsky Reservoir.  The river is remarkable in that it originates on the eastern slopes of the Ural Mountains in Asia, crosses the mountains, and mostly runs on their western slopes in Europe.  The Chusovaya River is widely used as a source of water.  In particular, its water is taken from the Volchikhinsky Reservoir, 37 km2 , to the Verkhneisetsky Reservoir to supply the major city of Yekaterinburg.  Fifteen smaller reservoirs are spread over about 150 tributaries of the river.
