Negative - Photograph, Opening of St. Andrews Battery, Queenstown, 29 Aug. 1919
Reproduced on p31 of 'Pioneers & Painters' Was destroyed in 1962 bushfire. Now Peter Franks Reserve, St Andrews On Friday 29th (August 1919) …, the Hon. S. Barnes, M. L. A., Minister of Mines, accompanied by Mr W. Everard, M.L.A., Mr. V. Dickson, secretary for Mines, and Mr. Merrin, Chief Mining Inspector, visited Smith's Gully for the purpose of opening, the new Government battery which has recently been erected. The party arrived punctually at 12.30, and was received by an assemblage of about 200 residents, including, those representing local prospecting and mining interests. At the mill house the Minister wished prosperity to mining on the old Queenstown field, and, in a few appropriate remarks, gave the battery the name of St. Andrew's. Then, as the stamps began to fall, three hearty cheers were given by the gathering. ….. The Queenstown field, dating back to the early sixties, might be regarded as a link that took them back to the Augustine age of gold mining in Victoria…From 1868 to 1918 the total yield of gold from the field was 274,606 fine oz. It might be that here, as elsewhere, deeper prospecting would give new life to the Queenstown goldfield. The miners of Queenstown, who through long year's had never lost faith in the possibilities of the field, felt that the purpose for which they were that day marked the beginning of a new era in the history of local reefing. …. The new mill is situated on the bank of the creek opposite the Queenstown Cemetery, and consists of a five head battery (Berdan pan) and 12 h.p. portable steam engine housed in a spacious structure of wood and iron. A concrete weir across the creek provides a good water supply, and all the necessary pumps, settling dams, etc., have been installed. Later on, should circumstances warrant it, it is pro-posed to erect Wilfley tables for concentrates. Eltham and Whittlesea Shires Advertiser and Diamond Creek Valley Advocate, Friday 5 September 1919, page 3This photo forms part of a collection of photographs gathered by the Shire of Eltham for their centenary project book,"Pioneers and Painters: 100 years of the Shire of Eltham" by Alan Marshall (1971). The collection of over 500 images is held in partnership between Eltham District Historical Society and Yarra Plenty Regional Library (Eltham Library) and is now formally known as the 'The Shire of Eltham Pioneers Photograph Collection.'

Photographs: The Maroondah Dam Wall Under Construction, 1921-1922
The Maroondah System was first and foremost developed as a functional component of Melbourne's Water Supply System. In addition to functionality, the Melbourne and Metropolitan Board of Works (MMBW) envisioned the Maroondah Reserve to be enjoyed aesthetically and recreationally by the public. This souvenir illustrates the realisation of the Maroondah System as a local recreational and tourist attraction in the early 20th century. The Maroondah Reserve gardens were landscaped with English-style ornamental stonework, exotic trees, flower beds and rose gardens. All features of the water supply system became widely celebrated as beauty spots that continue to be very popular to this day with tourists and locals alike. This souvenir is a product of that flourishing tourist trade. These water supply sites continue to enhance Melbourne’s charm and liveability and are now recognised as places of cultural and historic significanceThese photographs are invaluable in providing insight into many aspects of the Maroondah Reservoir’s early development. The dam wall is a distinctive example of early engineering techniques, with its gravity arch design and concrete construction. The construction of the dam wall represents an important advancement in the technology of dam-building.These images are part of a series of eight photographs which document the construction of the Maroondah Dam in the 1920s.melbourne metropolitan board of works, mmbw, melbourne water, photograph, water, maroondah dam, construction, wall -

Album - Hume Reservoir Australia Album - Detail plan and explanation, Department of Public Works, N.S.W, 1927
This set of photos is from a leather bound album bearing the inscription "HUME RESERVOIR AUSTRALIA" plus 'The Rt. Hon. L. C. M. S. Amery, P. C., M .P.' all inscribed in gold. It was presented to The Rt. Hon. L. C. M. S. Amery, P. C., M. P, Secretary of State for Dominion Affairs on the occasion of his visit to the Hume Reservoir on 2nd November 1927. This album is of local and national significance as it documents the planning and development of the Hume Reservoir up to 1927. It was the largest water reservoir in the British Empire. The album records the pioneering engineering work that went into its construction.2. Detail Plan and Section. Starting from the New South Wales and there will be an earthen embankment 430 feet 6 inches long which is retained by the North Wing Wall. Then come the sluice section 284 feet 3 inches long, the spillway 720 feet long and the South Wing Wall, making a total length of 1,042 feet 6 inches of concrete wall. Beyond the South Wing Wall is earth embankment again to a length of 3,827 feet. The Full Supply Level is R.L.626.00 and allowance has been made for a surcharge of 9 feet. A road will run along the top of the dam at R.L.642.00. The sluice section contains seven offlets, the three nearest the north wing wall being 13 feet in diameter for hydro-electric purposes and the other four 9 feet in diameter for regulation purposes only. There are to be stony sluice gates on the upstream ends of the outlets and needle valves on the downstream ends. The shock of the discharged water will be taken by a stilling pool. Trash racks will protect the intake ends of the outlets. Next comes the spillway section, which is curved on the downstream face, and carried up to within 15 feet of the full supply level. Above that will be a series of piers between which will be the flood gates and on top of which the roadway will be carried. The gates will be 20 feet wide and 15 feet high and will be 29 in number. They will slide down the face of the wall when opened for the escape of the water. The investigation of the control of this cascade of water was made by means of a model and as a result the form of “bucket” or energy dissipater shown on the section of the spillway was decided upon. The earth embankment in Victoria is being constructed by the State Rivers and Water Supply Commission of Victoria who are the Constructing Authority for that State under the River Murray Waters Agreement. The core of the embankment is of concrete 6 feet wide at the base tapering to 2 feet at the top end and is reinforced with steel rods from the level of the decomposed rock upwards. On the downstream side, at about natural surface level, is a tunnel for drainage and inspection purposes. Above the tunnel is a vertical layer of large stones to drain any seepage to the tunnel. Against the core wall is packed selected material of as impervious a character as can be got locally and beyond that the bank is carefully built up in horizontal layers by means of horses and wheel scoops. The upstream slope is 3-to-1 hardening to 2½-to-1 at the top and the downstream slope is 2½-to-1 hardening to 2.07-to-1 at the top. The thrust of the upstream toe is taken by a mass of granite blocks, and this face is protected by concrete laid in situ. The width of the bank at base is 650 feet and at top 32 feet.hume reservoir australia, river murray waters scheme, hume weir diagrams, hume plan details -

The first stage in the construction of the Dam foundations was carried out inside the levee bank which was at a sufficient height to protect from floods the work going on inside. A length of 300 feet of the Dam was left at a low elevation to allow of the river flowing over it in the second stage of the operations and at the ends of the concrete was brought up above flood level. To divert the river, a Coffer Dam was built across the old bed above and below the Dam site and tying into the end of the concrete wall built inside the levee bank.

Note the steam navvy at the end of the bit of curved work ready to take out the foundations for the energy dissipater. The tall concrete pillar is a portion of the work at the intersection of the main and south wing walls which was built in advance of the rest of the work to accommodate the tail tower of the cableway. The Tail Tower for the first stages of the work stood on the ground. Part of it is seen erected on the pillar while part of it is still in its original position. To command the concreting of the pillar end of the south wing wall a twin hoist tower of steel construction was erected at the end of the belt conveyor. This hoist is 160 feet high. The belt conveyor will at a later stage be raised for the concreting of the upper portion of the dam and the trestles are now being built up for that purpose. A drag line excavator with a 2 cubic yard capacity bucket is at work near the tail tower on the foundations for the south wing wall.

Great care is taken in cleaning the surface of the concrete before placing the next layer. A hose applies a jet of water with a pressure of about 150 pounds to remove laitance and all dirt, which is swept off with brooms. (Laitance is the weak, milky or powdery layer of cement dust, lime and sand fines that appear on the surface of concrete. ) The square block of concrete in the foreground is poured at the same time as the concrete surrounding it and acts as a key for the next layer. Usually large granite “plums” or displacers weighing from 2 tons to 8 tons are used for this purpose and are placed in position by the cableway, but while the cableway is out of action the other method has been adopted. In this view may also be seen some of the timber piles and sheeting which form the inner side of the coffer dam. The outer side is formed of steel sheet piling. The space between the two lines of piles is 20 feet wide and is filled with earth after the steel and timber lines have been bound together by steel tie rods.

Photograph
Taken between 1928 and 1930, depicted is the Bethanga Bridge under construction. The Bridge was completed in 1930 and was built to assist residents of the Bethanga district to travel to Albury. Other bridges would become submerged by the backed-up water of the Murray and Mitta Rivers so the Bethanga bridge was built two miles above the Mitta Weir. The Bethanga Bridge was built north of the future Hume Dam which would be completed in 1936. At 2430 feet long, Bethanga Bridge was the longest road bridge in Australia at the time of its completion. The Bridge is 20 feet wide and made up of nine 270 feet long spans. Materials used include ten tons of paint for the steel works; 1600 tons of steel; 900 tons of timber for the decking; and reinforced concrete for the piers. The tender for the construction was awarded to C. Ruwolt Pty. Ltd., engineers who were located on Victoria Street, West Richmond. The contract was awarded for £71,890. It was predicted between 250 and 300 men would find employment on the project. The news was well received by trade unions at the time as there had been a drop in available engineering work.This photograph is historically significant as it depicts the progress of the Bethanga Bridge construction, which was important infrastructure for the area. It is also a good example of methods used in the area to assist in travel over the river prior to the construction of the Hume Dam.Black and white rectangular photo printed on matte photographic paper.Reverse: 1997 3186 / 84-19-3 / This is the bridge. / It is not yet open to traffic / yet. will not be completed / until May next / It is a wonderful bridge the / pillars are 100 feet high. / KODAK PRINT Envelope Obverse: Peterson PHOTO / Hume Weir Envelope Reverse: BMM 84-20-1,2+3. bethanga bridge, lake hume, hume dam, hume weir, murray river, bridge, bethanga, albury -

Photograph, Unknown c.1930s
This image shows Bethanga Bridge, which was constructed between 1927 and 1930 in Albury, NSW. The bridge was a necessity due to the building of the Hume Dam (Wier), 1919-1936. Bethanga Bridge is a long, nine-span, riveted-steel, variable depth, Pratt Truss road bridge of nine principal spans of 82 metres and a total length of 752 metres over the flooded valley of the Murray River, now part of Hume Reservoir. Because of its unique location, over the waters of a dam with the border running down the centre of the body of water, the Bethanga bridge is the only built structure shared by both New South Wales and Victoria. It was built 1.6 kilometres upstream of the dam and in 1961 was raised 300mm, with a concrete deck replacing the original wooden deck. The State Rivers and Water Supply Commission of Victoria and the New South Wales Department of Public Works were responsible for the construction works for the Hume Weir under the River Murray Waters Agreement. It is apparent that a similar joint arrangement was made for the construction of the Bethanga Bridge as part of the Hume Weir works.This photograph of the Bethanga Bridge is of historical significance as it showcases the architectural skills of Percy Allen and Vincent Packer. Additionally, it reveals the environmental landscape of the 1920s-1930s, is linked to the Hume Dam and both New South Wales and Victorian heritage. Unmounted black and white rectangular photograph.

Photograph - Bethanga Bridge
The Bethanga Bridge was built between 1927 and 1930 as a joint venture between Victoria and New South Wales as part of the Hume Dam project as a key element of the River Murray Waters Agreement. It consists of nine spans of 82 metres long. Each span is supported between double reinforced concrete pylons and a riveted steel camel back Pratt truss. The overall span of the bridge is a length of 752 metres. It was completed in 1929 at a cost of £194,000. The road deck was initially constructed from timber but was replaced in 1961 with a concrete waffle slab deck 7.7metres wide. In 1961 the bridge deck and truss structure were raised 300 millimetres to allow for the enlargement of the lake. The bridge was designed in NSW by road engineer Percy Alan and the trusses were built by the Charles Ruwolt Pty. Ltd. Charles Ruwolt Pty. Ltd. was originally established by Charles Ruwolt as a foundry at Wangaratta in 1902 and transferred its operations to Richmond, Melbourne in 1914. By 1938 it had become one of the biggest engineering companies in Australia. After Charles Ruwolt’s death in 1946, Vickers Ltd. acquired the company and in 1948 the firm became known as Vickers Ruwolt Pty. Ltd. Because of the Bethanga Bridge’s unique location, over the waters of a dam with the border running down the centre of the body of water, the Bethanga Bridge is the only built structure shared by both Victoria and New South Wales. As the border of New South Wales aligns with the southern bank of the Murray River all of the other bridges along its length are deemed to be in New South Wales. The Bethanga Bridge is listed on both the New South Wales State Heritage Register and the Victorian Heritage Database. In 2015 the Bethanga Bridge was nominated for a heritage award by the Institution of Engineering Australia.These images are significant because they document the construction of a bridge which links Victoria and New South Wales and has been recognised for its historical, technical and engineering significance.A collection of photos documenting the construction of the Bethanga Bridge which links the States of Victoria and New South Wales as part of the construction of the Hume Dam .bethanga bridge, hume dam constuction, charles ruwolt, percy allan engineer
