Where is mundaring weir

This can be combined with a walk to the site of No 2. He surveyed several possible sites in the hills outside Perth. One of his reasons for recommending this site was what appeared to be foundations of solid granite.

There were no gaugings to determine inflow but he was confident the large hilly and rocky catchment would fill the reservoir every year. Thomas Hodgson wrote in his recommendation of the chosen reservoir site that A concrete dam might be made ft. Unless it is closed for operational reasons, you can walk across the wall during the day.

A channel, lined with stone, was excavated in the riverbed to carry the water clear of the dam. Work on the first two steam pumping stations and the pipeline near the weir was delayed in case the site had to be abandoned. What was thought to be bedrock, turned out to be an enormous boulder. Its removal revealed an extensive fault in the underlying granite.

The rift was excavated to 90 ft below the riverbed where the material filling it was compact. On such site visits he stayed at a hotel near the weir — you can do the same today. All material for the wall except stone had to be brought to the site. A spurline from the existing railway line 10 kilometres north was built for this purpose. The dam and reservoir form the boundary between the suburbs of Reservoir and Sawyers Valley.

The dam impounds the Helena River. European populations did not grow significantly until construction of the dam in the late s. This involved the building of a railway line from Mundaring to the Mundaring Weir site. The Irish Australian engineer C. 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 lake created by the dam was known as the Helena River Reservoir , however it is now known as Lake C. The owner of the dam, the Water Corporation, refers to the weir as Mundaring Dam on its website, but no other authority, such as Geographic Names, or Geosciences Australia uses this term. The Mundaring Shire uses an image of the Mundaring Weir in its logo. In the early s the downstream dam from the weir —the Lower Helena Pumpback Dam—was constructed.

Like any structure of its age and design, the weir requires monitoring and repairs and maintenance. On the original structure the central small building was used for aspects of monitoring the weir's internal status — it was rebuilt on the heightening of the dam, although it was no longer used for its original purpose.

The pathogens can be difficult to remove, putting our drinking water at risk and potentially making people sick. There are also restrictions on other activities such as off-road driving, camping, lighting fires and littering. Failure to comply with these rules may result in an infringement or prosecution. Access is not permitted on the reservoirs or in the streams flowing into it.

Failure to comply may result in prosecution. Please report unmarked safety hazards, suspicious behaviour or pollution to 13 13 For additional information about any of our dams, please call us on 13 13 Capacity — Parkland at Mundaring Weir.
