This image taken between 1920-1930 depicts open-cut hydraulic sluicing at the Three Mile Mine, located about five kilometres south of Beechworth. Alluvial, or surface, mining began on this site in the 1850s, but was soon replaced by hydraulic sluicing methods. By the start of 1880 it is estimated that nine hundred miles of water races had been cut though soil and rock in the Beechworth district. Hydraulic sluicing employs high pressure jets of water to blast away large areas of earth and wash it down to be run through a sluice box. Gold gets caught in the sluice and the remaining slurry is washed away. Large water quantities were required for hydraulic sluicing, and the long water races and deep tailraces that were constructed were considered great engineering feats. This method of mining is extremely effective, but causes significant environmental damage and impacts to waterways and agricultural operations. Miners at Beechworth built extensive networks of races and dams to secure reliable supplies of water on a scale far greater than elsewhere in Victoria. By the 1880s Beechworth's water barons continued to hold more than half of all the water right licences on issue and undertook sluicing operations on a massive scale. The manipulation of surface and ground water via race networks was well planned and recorded in detail by local mining surveyors. The maps that were created, combined with modern geo-spatial technologies, provide a vital key in understanding the great lengths to which miners went to capture and control critical water resources. Today, Three Mile mine is called Baarmutha. The Three Mile Mine was unproductive until 1865 when John Pund and three other miners secured a fifteen year license and constructed a water race from Upper Nine Mile Creek to Three Mile Creek. In the early twentieth century Pund & Co. averaged over one thousand ounces of gold per year from the mine. After Pund's death in 1915, GSG Amalgamated Co operated the site, continuing sluicing until 1950. This image of hydraulic sluicing methods shows the extent of water-works engineering in the landscape. This photograph has historic and research potential for understanding changes to the landscape, the evolution of mining methods, and the extensive construction, manipulation and management of water networks in the Beechworth district.

As part of the push to cut electricity costs and diversify supply, the Victorian Government (circa 1930) implemented the conversion strategy from mainly brown coal supply to hydro - electricity. The Kiewa Hydroelectric Scheme became the largest scheme of its kind in the State Of Victoria and the second largest scheme in Australia. Clover Dam and Power Station were built by the State Electricity Commission of Victoria as part of the Kiewa Hydro Electric Scheme from the late 1930's to the early 1940's. This dam was constructed to supply water to feed four turbines (62 mega watts) at the West Kiewa Power Station. This was at the forefront of sustainable "Green" energy. Costs associated with power supplies is still a major incentive of governments, however environmentally friendly alternatives such as wind and nuclear have also made inroads. The Kiewa valley and its surrounding alpine catchment were looked at(Victorian State Government), from the beginning of the twentieth century as a source of alternate power for an ever-increasing demand for electricity by growing population and heavy industrial areas within Melbourne City and State regions. Construction of dams, such as Clover Dam provided the large quantity holding areas of water required to turn the turbines at the various power stations to provide the electricity needed. The impact of these controls by moderating water run-off from the alpine regions is beneficial in reducing flooding from thawing of snow on the alps. This by-product allows agriculture and grazing to be less vulnerable to seasonal flooding thereby resulting in a more stable annual production level.Black and white photograph of Clover Dam with Kiewa River in flood. .5mm white boarder on 3 sides of photo.Handwritten on back of photograph in black pen - Kiewa in flood.
