Albury Sports Ground: Albury Sports Ground (also known as "Albury Oval") is a sporting ground located close to the central business district of Albury, Australia.  The oval is near the NSW bank of the Murray River, with a historic grandstand on the north-western flank, and a members' club with a grandstand and changing rooms on the eastern wing.  The venue also incorporates a netball court in the north-eastern corner, while the Albury Swim Centre is adjacent to the west.  The ground is part of a string of parks and gardens between the Murray River and Wodonga Place that include the Albury Botanic Gardens, Hovell Tree Park, Noreuil Park, Australia Park, and Oddies Creek Park.

Bonegilla Migrant Reception and Training Centre: The Bonegilla Migrant Reception and Training Centre was a camp set up for receiving and training migrants to Australia during the post World War II immigration boom.  The camp was set on 130 ha near the small town of Bonegilla in north east Victoria, between the Hume Dam and the city of Wodonga.  The site was a former World War II Australian Army base, and is adjacent to the current Latchford Barracks.  The camp opened in 1947 and operated until 1971, over which period it received over 300,000 migrants.  It is estimated that over 1.5 million Australians are descended from migrants who spent time at Bonegilla.

Hume Dam: Hume Dam, formerly the Hume Weir, is a major dam across the Murray River downstream of its junction with the Mitta River in the Riverina region of New South Wales, Australia.  The dam's purpose includes flood mitigation, hydro-power, irrigation, water supply and conservation.  The impounded reservoir is called Lake Hume, formerly the Hume Reservoir.  It is a gated concrete gravity dam with four earth embankments and twenty-nine vertical undershot gated concrete overflow spillways.

Holcomb Rock Dam: The Holcomb Rock Dam is a concrete dam across the James River near Lynchburg, Virginia.  The project consists of a concrete dam across the river, an earthen embankment canal on the right bank, and a power house where water is discharged to generate electricity.  Per the 2008 annual generation report, the project generated 6,089,209 KW-hours.

Gateway Island, Victoria: Gateway Island is an unpopulated suburb of the City of Wodonga local government area in northeast Victoria, Australia, adjacent to the Murray River and bounded in the south by the Wodonga Creek.

Albury–Wodonga: Albury–Wodonga is the broad settlement incorporating the twin Australian cities of Albury and Wodonga, which are separated geographically by the Murray River and politically by a state border: Albury on the north of the river is part of New South Wales while Wodonga on the south bank is in Victoria.

Murray River Queen: Murray River Queen is an Australian paddle ship built at Hindmarsh Island in 1974 as a luxury passenger cruise boat.  She was a tourist boat carrying passengers on the Murray River in South Australia.  For many years, her home port was Goolwa where she offered week-long cruises operated by her builders, the Veenstra family.  She was the first of several large boats built by the Veenstras for the Murray River, they later also built the M.V. Murray Explorer and PS Murray Princess.

Murray River Flag: The Murray River Flag is flown from paddle steamers and other vessels in the Australian States of New South Wales, Victoria and South Australia that ply the waters of the Murray-Darling river system.  Little is known about the flag's early history but it may have originated as far back as 1850 when the formation of the Murray River League was announced.  R. W. Beddome, founder of the League, enthused "Up with the Murray flag."  No fragments of the original Murray River Flag are known to exist and three variants have passed down to the present day.

Deep Creek Dam: The Deep Creek Dam located about 8 miles north of Oakland, Maryland, consists of an earth and rockwall dam across a tributary of the Youghiogheny River that was completed in 1925 by the Pennsylvania Electric Company.  Construction of the dam created the Deep Creek Lake.  The twin water turbine 20 MW hydroelectric plant, acquired by Brookfield Renewable Power, Inc., in 2005, became operational in 1928.  The Federal Energy Regulatory Commission licensed the dam and hydroelectric plant in 1968, but released the licensing to Maryland effective 1994.  Under a 1994 agreement with the Maryland Department of Natural Resources, the dam is operated to control waterflows to maintain the river temperature and dissolved oxygen levels to assist downstream fisheries with the intent of increasing the number of trout as well as to enable recreational whitewater activities (kayaking, canoeing, and commercial rafting) on the Upper Youghiogheny River into which the dam releases.  The Maryland Department of the Environment water appropriations permit under which the dam operates, which is renewable, will expire on January 1, 2018.
