Update 23 January 2018

No doubt some readers will have been watching the slow march of the pipeline up the hill from William Hovell Drive towards the souther boundary of the Reserve (see photo below for progress as at 22nd January).

We heard today that preparatory work will start on the Reserve next Wednesday (30th January). This will comprise erection of fencing along the pipeline corridor and around the two storage areas along the route (indicated in yellow on the map below), tree protection measures, erosion sediment controls and tree pruning to allow machinery access. No doubt there will be some minor disruption while this takes place and before the cross-pipeline pedestrian walkways (indicated in green on the map below) are in place.

As soon as we know what the likely hours of disruption to those pedestrian walkways will be when the pipeline construction is in progress that information will be added to this web page.

Work commenced on the William Hovel Drive end of the pipeline last week. The photo below shows what we can expect in terms of disturbance in the fenced-off corridor.

14 November 2018

Preparatory work for the pipeline has commenced at the William Hovell end and the date for erection of the fences along its corridor through the Reserve is getting closer (though no firm date is available yet).

We'll provide an update as soon as information is available.


18 August 2018

We have been advised by the pipeline contractors that the erection of the fence along the pipeline corridor though the Reserve is still a few weeks away. They also advised us that the pipeline installation will commence down at William Hovell Drive and work its way up through Bottom Pinnacle to the Reserve. Among other things, this allows them to leave the Reserve corridor unfenced for longer.

Themeda (kangaroo grass) Rescue

A small group is currently trying to rescue as much Themeda as possible from the pipeline corridor and transplant it to a regeneration area in the Weetangera paddock. This usually takes place on Saturday mornings.

If you can spare some time to assist to get as much as possible rescued before the fencing goes up then please contact Len ( and he will let you know the details each week. Any time you that you can spare to assist will be gratefully appreciated. Establishing a strong colony of Themeda in an area currently dominated by exotic grasses will enhance the natural value of the Reserve. As we control many of the invasive broadleaf species in the Reserve and now that kangaroo numbers have been reduced we are finding Themeda becoming more prevalent and dense, so anything we can do to encourage its spread will be worthwhile.


24 July 2018

Preparation has been underway since mid-2016 for the construction of the pipeline running from the Weetangera water tanks through the Pinnacle Nature Reserve to the new suburb of Whitlam between William Hovell Drive and the Molonglo River.

The fotpin Coordinating Committee has been kept informed and consulted throughout the planning stages and has updated members from time to time. The most comprehensive update can be found in fotpin Update #21 [pdf398 kB].

[ Note that the pipeline has been, and continues to be, referred to by various names: Whitlam Pipeline, Whitlam Water Main, Molonglo Water Main, Molonglo 3 Water Supply Main, etc.]

This page will attempt to keep members and Reserve users up to date with developments, especially those that may affect their access to certain parts of the Reserve.

If you have any questions or comments from a Reserve users perspective, don't hesitate to email these to us at

July 2018

Since early July 2018, signs of the construction project have started to appear on the Reserve, with the fencing of some of the construction areas. A notice and map explaining what is happening has been displayed adjacent to the fences; copies are included below.

Molonglo 3 Water Supply Main – Weetangera Reservoir to
William Hovell Drive Project

Works will be undertaken from July 2018 until February 2019 in the Pinnacle Nature Reserve and adjoining land to construct a bulk supply watermain to provide water to the new Molonglo 3 Precinct.

Some of the Reserve will be fenced off to maintain public safety. There will be designated walkways around and through the fenced site. A secure site will be required to be maintained for the duration of the works. More fencing will be installed soon after commencement of the project.

Please refer to attached sketch for fencing and access arrangements.
