Goulburn Weir is a weir built between 1887 and early 1891 across the Goulburn River near Nagambie, Victoria, Australia.It was the first major diversion structure built for irrigation development in Australia. The weir also forms Lake Nagambie where rowing regattas and waterskiing tournaments are held.
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. There are many designs of weir, but commonly water flows freely over the top of the weir crest before cascading down to a lower level.
The Goulburn River, a major inland perennial river of the Goulburn Broken catchment, part of the Murray-Darling basin, is located in the alpine, Northern Country/North Central, and Southern Riverina regions of the Australian state of Victoria. The headwaters of the Goulburn River rise in the western end of the Victorian Alps, below the peak of Corn Hill before descending to flow into the Murray River near Echuca, making it the longest river in Victoria at 654 kilometres (406 mi). The river is impounded by the Eildon Dam to create Lake Eildon, the Eildon Pondage, the Goulburn Weir and Waranga Basin.
Irrigation is a widespread practice required in many areas of Australia, the driest inhabited continent, to supplement low rainfall with water from other sources to assist in growing crops and pasture. Overuse or poor management of irrigation is held responsible by some for environmental problems such as soil salinity and loss of habitat for native flora and fauna.
The Goulburn Weir allows water to be diverted by gravity via the Stuart Murray Canal and Cattanach Canal for off-river storage in the Waranga basin, for later use in irrigation.
The weir is 209 metres long by about 16 metres high. Its design was considered very advanced for its time, so much so that it featured on the back of half-sovereign and ten-shilling notes from 1913 to 1933. The structure also contained one of the first hydro-electric turbines in the southern hemisphere, used to supply power for lifting and lighting.
After more than 90 years of continuous service, many of the weir's components were in urgent need of replacement. Stabilisation works were done in 1983 and in 1987.
The weir raises the level of the Goulburn River so that water can be diverted, by gravity, along the main irrigation supply channels: Stuart Murray Canal, Cattanach Canal, East Goulburn Main Channel. The weir services nearby farming of crops including wheat, stock and domestic supplies.
Approval for the construction of the Goulburn Weir was granted on the 16th of December 1886, by the passing of The River Goulburn Weir Act 1886. This act allowed the treasury of Victoria to issue up to £20,000 for the construction of the weir and related works. A further £75,000 was approved under The Water Supply Loans Act 1887.
The construction of the weir began with the construction of six tunnels designed to pass the normal river flow. These would allow the construction of the masonry section of the weir to proceed with the river flows passing through the tunnels underneath. The tunnels were fitted with sluice gates that could be closed once the weir was completed allowing structure to raise the height of the river upstream.
The main body of the weir is constructed from concrete masonry, that is large concrete blocks that were bedded and jointed in cement mortar. It is backed with steps of granite blocks, each to the height of a course (2 feet).
The stone and sand for the concrete was sourced locally, the stone was quarried from a hill two miles (3.2 km) to the north and the sand was obtained from various pits within four miles (6.4 km) of the weir. The granite for the weir was sourced from Mount Black, 15 miles (24 km) to the south west.
The weir was completed, the tunnel sluices closed down and the river allowed to flow over the weir in the early part of December 1890. The water level upstream was slowly raised and storage reached its full supply level towards the end of July 1891.
The final cost of the weir works was £106,262.
The Murray River is Australia's longest river, at 2,508 kilometres (1,558 mi) in length. The Murray rises in the Australian Alps, draining the western side of Australia's highest mountains, and then meanders across Australia's inland plains, forming the border between the states of New South Wales and Victoria as it flows to the northwest into South Australia. It turns south at Morgan for its final 315 kilometres (196 mi), reaching the ocean at Lake Alexandrina.
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.
The Eildon Dam or Eildon Weir, a rock and earth-fill embankment dam with a controlled spillway across the Goulburn River, is located between the regional towns of Mansfield and Eildon within Lake Eildon National Park, in the Alpine region of Victoria, Australia.

Lake Nagambie is a 170-hectare (420-acre) man–made reservoir located in the Goldfields region of Victoria, Australia. The lake was formed by the damming of the Goulburn River by the Goulburn Weir. The town of Nagambie is on its shores.
Tahbilk Winery is an Australian winery located 120 km (75 mi) north of Melbourne between the townships of Seymour and Nagambie in the Nagambie Lakes a sub region of Goulburn Valley Wine Region. It was established in 1860, and claims to be the oldest family-owned winery in Victoria. The winery is part of Australia's First Families of Wine, a prominent Australian wine alliance.
The North–South Pipeline, also known as the Sugarloaf Pipeline, is a water pipeline in Central Victoria, Australia, northeast of Melbourne that is part of Victoria's water system, acting as a link between Melbourne's water grid and the Murray-Goulburn water grid, supplying water via a series of existing and proposed pipelines. The 70-kilometre pipeline was connected to Melbourne in February 2010 to carry water from the Goulburn River to Melbourne’s Sugarloaf Reservoir. It is the government's policy that it only be used in times of critical human need: when Melbourne’s total water storages are less than 30% full on 30 November of any year. The pipeline can transfer a portion of Lake Eildon’s water that is set aside for Melbourne, called the critical water reserve. This was 38,400 megalitres at 2 June 2014, and any changes are based on Goulburn-Murray Water’s advice.
The Mulwala Canal is an irrigation canal in the southern Riverina region of New South Wales, Australia. It is the largest irrigation canal in the Southern Hemisphere. The canal, starting at Lake Mulwala, diverts water from the Murray River across the southern Riverina plain to the Edward River at Deniliquin. The channel has an offtake capacity of 10,000 megalitres (ML) per day and annually supplies over 1,000,000 ML to 700,000 hectares in the Murray Irrigation Area.
Vaalharts Storage Weir is a dam in South Africa. It was established in 1936.
