Lower Helena Pipehead Dam
The Lower Helena Pipehead Dam, also known as the Lower Helena Pumpback Dam, catchment and pipeline are a part of the Goldfields Water Supply operations at Mundaring Weir, some distance east in the same valley, in the Darling Range in Western Australia. The suburb Helena Valley, Western Australia, Helena Valley is a few kilometres downstream of the dam. The dam was first constructed in the early 1970s, on the Helena River at a location on the southern boundary of the suburb of Darlington, Western Australia. By the 1980s and 1990s, the catchment and water quality saw a number of studies and reports. Into the 2000s, further research continued, and the upper parts of the catchment area were being considered as restricted activity zones.

Goldfields Water Supply
The Goldfields Water Supply Scheme is a pipeline and dam project that delivers potable water from Mundaring Weir in Perth to communities in Western Australia's Eastern Goldfields, particularly Coolgardie and Kalgoorlie. The project was commissioned in 1896 and completed in 1903. The pipeline continues to operate today, supplying water to over 100,000 people in over 33,000 households as well as mines, farms and other enterprises. Water scarcity During the early 1890s, thousands of settlers had travelled into the barren and dry desert centre of Western Australia seeking gold, but the existing infrastructure for the supply of water was non-existent, and an urgent need arose. Prior to the scheme, water condensers, irregular rain, and water trains were part of the range of sources. Railway dams were essential for water to supply locomotives to travel to the goldfields. Origins of the scheme Throughout the 1890s, water availability issues in Coolgardie and in the Kalgoorlie-Boul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mundaring Weir
Mundaring Weir is a dam (and historically the adjoining locality) located from Perth, Western Australia in the Darling Scarp. The dam and reservoir form the boundary between the suburbs of Reservoir and Sawyers Valley. The dam impounds the Helena River. History A soldier, Ensign Robert Dale, became the first European to explore the region in 1829. European populations did not grow significantly until construction of the dam in the late 1890s. This involved the building of a Mundaring Weir railway line from Mundaring to the Mundaring Weir site. The Irish Australian engineer C. Y. O'Connor was involved in the design of a scheme that transported water to the Eastern Goldfields of Coolgardie and Kalgoorlie in the eastern part of Western Australia. The weir was completed in 1903. The lake created by the dam was known as the Helena River Reservoir, it was renamed as Lake C.Y. O'Connor in 2004. The owner of the dam, the Water Corporation, refers to the weir as Mundaring Dam on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darling Range
The Darling Scarp, also referred to as the Darling Range or Darling Ranges, is a low escarpment running north–south to the east of the Swan Coastal Plain and Perth, Western Australia. The escarpment extends generally north of Bindoon, to the south of Pemberton. The adjacent Darling Plateau goes easterly to include Mount Bakewell near York and Mount Saddleback near Boddington. It was named after the Governor of New South Wales, Lieutenant-General Ralph Darling. History The feature was first recorded as General Darling Range by Charles Fraser, Government Botanist with Captain James Stirling aboard in March 1827. Maps from the 1830s show the scarp labelled " General Darlings Range"; this later became Darling Range, a name by which the formation was still commonly known in the late 20th century despite common understanding of it being an escarpment. There is also a tendency to identify the locations on or to the east of the scarp as being in the "Perth Hills" (or simpl ...

Helena Valley, Western Australia
Helena Valley is the name of a river valley and a locality in the foothills of the Darling Scarp in Perth, Western Australia. Geology The river valley is the centre of the catchment of the Helena River and extends from the edge of the Darling Scarp where Boya, Gooseberry Hill and Helena Valley define the "mouth" of the valley that opens to the Swan Coastal Plain, east and south east past Mundaring Weir and Lake C.Y. O'Connor to its origins in the region of Mount Dale. The soils of Helena Valley are characteristic of the eastern Swan Coastal Plain, ranging from sand to loam and clay, with a neutral pH tending towards moderately acid. Locality The locality is within the Shire of Mundaring, situated just south west of Boya and Greenmount Hill, 5 kilometres from Midland. It consists of many rural houses, but also contains six estates, and a shopping centre located in one of the estates. Helena Valley Primary School is located at the base of Greenmount Hill.http://www.helena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helena River
The Helena River is a tributary of the Swan River in Western Australia. The river rises in country east of Mount Dale and flows north-west to Mundaring Weir, where it is dammed. It then flows west until it reaches the Darling Scarp. It passes through the western edge of the Darling Scarp between Gooseberry Hill, and Greenmount Hill before joining the Swan River at the southern edge of the historic town, now suburb, of Guildford. Catchment area Many of the tributaries of the Helena River are unnamed due to their seasonality and size. However, Nyaania Creek on the northern side of the catchment and Piesse Brook on the southern side are significant through moving through built up areas, which also makes them susceptible to urban environment issues. Upper Helena catchment (i.e. above Mundaring Weir) has on the north side of Lake C.Y. O'Connor (formerly the Helena River Reservoir) a range of named creeks that occur in State Forest no 71 and 13: *Manns Gully *Chinaman Gully *J ...

Darlington, Western Australia
Darlington, Western Australia, is a locality in the Shire of Mundaring on the Darling Scarp, bisected by Nyaania Creek and north of the Helena River. Location About one kilometre to the west of Darlington and lower on the Darling Scarp lies the locality of Boya. Between Darlington and Boya there are two abandoned quarries: C. Y. O'Connor's "Fremantle Harbour Works Quarry", now known as "Hudman Road Amphitheatre", and the Mountain Quarry which is also called Boya quarry.

Dams In Western Australia
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
