Department of Climate Change, Energy, the Environment and Water / Bourkes Gorge No 2 - Major Rehabilitation Works - DECC-573-2009

Location & Access

The site is situated within Kosciuszko National Park in the Upper Murray area of the Snowy Mountains Region. Bourkes Gorge runs parallel to the Bogong Creek, between Scammels Ridge and Grey Mare Range.

Access to the site is via Alpine Way and Bourkes Gorge Road. Bourkes Gorge Road (unsealed) ends 11.7km from the Alpine Way at Bourkes Gorge No. 1 Spoil Dump. Access to Bourkes Gorge No.2 Spoil Dump is along a minor track that runs across the top section of the spoil dump and heads in a southerly direction through for about 800m. This track follows the course of the former railway track to Spoil Dump No. 2

Site description

The site is a spoil dump that fills the steep valley of a tributary creek flowing to Bogong Creek.  The slope is estimated to have a height of 60m and is at and angle of approximately 38 degrees.  It is approximately 150m wide across the valley and extends about 250m upstream along the tributary creek that has been blocked by the dump.

The tributary creek now runs on top of the spoil dump and sediment has been deposited on the upstream section of the spoil dump creating a wetland condition.  An 8m washout scar has been left in the southern side of the spoil dump and erosion of this area down the creek continues during peak flows.

In addition to the rock spoil, small quantities of scrap metal, timber and concrete may be present at this site.

Contract Objectives

The objectives of the rehabilitation works are:

Ø       Re-shape the spoil dump to a more stable slope.

Ø       Construct an environment that favours re-vegetation and habitation of the endemic species.

Ø       Integrate the site into the surrounding environment.

Ø       Construct a channel through which high flow events can be transported across the site without scouring, or rendering the site unsafe.

Ø       Slow any high flow events to limit the scour effects on the downstream environment.

Ø       Record and capture any significant heritage items found at the site.

Ø       Assess any contamination or general construction waste found at the site, and if appropriate, remove to an approved disposal site. 

Ø       Improvement in the visual amenity of the site and over time.

Ø        Retention of any cultural heritage values identified during construction.
